Title: Multi-edge oscillating saw blade

Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation-in-part of U.S. patent application Ser. No. 29/797,192 (Attorney Docket No.: WARD-0001-D01), filed Jun. 29, 2021, and titled “MULTI-BLADE OSCILLATING TOOL”, and which is hereby incorporated by reference in its entirety. 
    
    
     BACKGROUND 
     Any discussion of the related art throughout this specification should in no way be considered as an admission that such art is widely known or forms part of the common general knowledge in the field. 
     Oscillating tools are used in a variety of applications for sawing, cutting, sanding, polishing, and grinding. Oscillating tools (sometimes called multi-tools) are configured to oscillate various accessory attachments that can be used to saw, cut, sand, polish, or grind a work piece. These accessory attachments are fitted to the oscillating tool by a mechanism that allows the attachment to be moved rapidly (i.e., oscillated) back and forth about an axis of oscillation. For example, an oscillating tool fitted with an offset blade can be used to cut nails or screws flush with a surface. Some oscillating tools allow the accessory attachment to be rotated into different orientations when attached to the tool, allowing, for example, an oscillating blade edge to reach cutting areas that would be unreachable using a rotating or reciprocating saw. 
     One significant issue with working with oscillating tools is that blade attachments tend to wear out or break during use. When this happens, a blade attachment must be removed from the tool and discarded, then replaced with a new blade attachment before work can continue. Further, the user may continue to use the worn or damaged blade to delay replacement, which may result in substandard work being performed with the worn or damaged tool. The replacement process can result in wasted time as work must be stopped, the blade attachment removed from the oscillating tool, a new blade attachment procured, and then secured to the tool. Such a system can also result in wasted monetary and material resources as the entire blade attachment must be discarded whenever the blade edge is worn out or damaged. 
     SUMMARY

     DETAILED DESCRIPTION 
     The present disclosure teaches a multi-edge blade accessory attachment for use with an oscillating tool (or multi-tool) that includes multiple cutting edges arranged sequentially from the distal end of the blade. Within aspects of the present disclosure, these multiple cutting edges are formed such that when a first cutting edge becomes worn out or damaged, it can be broken away from the multi-edge blade in such a way that reveals an additional cutting edge. Under certain aspects of the present disclosure, the multi-edge blade includes a first row of cutting teeth situated across the distal edge of the blade, which realize a first cutting edge. Under aspects of the present disclosure, the multi-edge blade further includes a row of perforations across the distal end of the blade, a spaced distance behind the first row of cutting teeth. Under some aspects of the present disclosure the multi-edge blade further includes at least one additional row of perforations across the distal edge of the blade, with each row of perforations situated a spaced distance behind the row in front of it. Under aspects of the present disclosure the perforations are selectively sized and shaped such as to form a breakaway line. This breakaway line allows the cutting edge in front of a row of perforations to be snapped free of the multi-edge blade by applying a twisting force orthogonal to the plane of the multi-edge blade. Under these aspects of the present disclosure the perforations are selectively sized and shaped such that a new row of cutting teeth will be formed along the new distal edge of the multi-edge blade after a cut-away edge is broken away. In this way, a single multi-edge blade can be attached to an oscillating tool and provide multiple cutting edges, which can be used sequentially without ever removing the blade from the tool. 
     In some aspects of the present disclosure, the first row of cutting teeth and the one or more rows of perforations are oriented in straight lines substantially perpendicular to an intended axis of oscillation of the multi-edge blade, forming a “flat” blade as shown in  FIGS.  1 A,  1 B,  2 A, and  3 A . In other aspects of the present disclosure, the first row of cutting teeth and the one or more rows of perforations are oriented in a semi-circular arrangements, forming a “rounded” blade as shown in  FIGS.  2 B and  3 D . In other aspects of the present disclosure, the first row of cutting teeth and the one or more rows of perforations are oriented in a diagonal line with respect to the axis of oscillation, forming an “angled” blade as shown in  FIGS.  2 C and  3 G . Within certain aspects of the present disclosure, the axis of oscillation of the multi-edge blade is oriented along the centerline of the multi-edge blade. 
     Under certain aspects of the present disclosure, the multi-edge blade further includes an attachment socket on the proximal end of the blade that is configured to mate with an oscillating tool. Certain aspects of the present disclosure further include a cutting edge removal tool, as shown in  FIGS.  4 A- 4 D  which can be used, in certain applications, to break away worn out or damaged cutting edges from the multi-edge blade. In other aspects of the present disclosure, cutting edges can be removed from the multi-edge blade using a conventional tool (e.g., gripping the cutting edge with a pair of plyers and twisting orthogonal to plane of the blade). It should be noted that within the present disclosure the terms “multi-edge blade,” “multi-edge saw blade,” “multi-edge oscillating saw blade” are used interchangeably to refer the multi-edge blade accessory attachment of the present disclosure. The use of these terms is for ease of explanation, and no limitations should be read into any aspect of the present disclosure with respect to the use of one term over another. 
     Looking now to  FIG.  1 A , a first example multi-edge oscillating saw blade  101  for use with an oscillating saw with a flat edge and including three breakaway cutting edges ( 110   a ,  120   a ,  130   a ) and four cutting edges total is depicted. As shown in  FIG.  1 A , the multi-edge blade  101  is formed generally in a plane and includes a first row of cutting teeth  115   a  along the distal edge of the blade. Situated a spaced distance behind first row of cutting teeth  115   a  is a first row of perforations  125   a . Similarly, a second row of perforations  135   a  is situated behind first row of perforations  125   a , and a third row of perforations  145   a  is situated behind second row of perforations  135   a . As multi-edge blade  101  is designed to provide a flat cutting edge, first row of teeth  115   a  and first, second, and third rows of perforations ( 125   a ,  135   a , and  145   a , respectively) are all oriented in straight lines substantially perpendicular to the axis of oscillation  170   a.    
     One of skill in the art will appreciate that the spacing distance between rows of perforations should be selected to provide sufficient room for the teeth to be fully formed in each row, sufficient remaining material to provide sufficient strength for the blade to perform without inadvertent separation of rows of cutting teeth, and to provide sufficient stiffness for the blade to perform the associated task (e.g., cutting on a surface of a suitable material). Certain considerations to determine the spacing distance include: the depth and orientation of the teeth in a cutting row, the material utilized to fabricate the blade, the fabricated thickness of the blade, the material intended for cutting with the blade, the forces applied to the blade during cutting (e.g., down force by the operator, oscillating speed and amplitude, etc.), the intended cutting technique utilized with the blade (e.g., whether torsion forces, perpendicular forces, etc., are expected to be experienced by the blade in use), the total number of connecting portions of the blade between rows of cutting teeth, and/or the number and arrangement of perforations utilized to make sequential rows of cutting teeth easy to remove. It will be understood that the spacing distance between each row of cutting teeth may be the same, or may be varied. For example, where the thickness of the blade material tapers (e.g., thicker at the base toward the attachment socket  160   a , and thinner toward the distal edge of the blade), the spacing distance may be varied appropriately (e.g., a longer spacing distance to provide additional securing material, and/or a shorter spacing distance to reduce the lever arm applied by incidental forces or strikes on the blade that may tend to cause an inadvertent separation). In another example, the total lever arm and vibration profile of the blade may vary according to which of the rows of cutting teeth is actively in the cutting position, with the spacing distance varied appropriately (e.g., a longer spacing distance for the more distal rows, for example to provide additional securing material, or a shorter spacing distance for the more distal rows, for example to reduce the lever arm and/or to limit the overall length of the blade). In certain embodiments, the spacing distance may be slightly larger than the extent of the teeth in a cutting row, for example with a selected offset distance (e.g., 0.1″ greater than the extent of the teeth, 0.5″ greater than the extent of the teeth, etc.), and/or at a selected ratio (spacing distance:teeth extent) such as 1.05, 1.10, 1.5, 3.0, etc. In certain embodiments, the spacing distance may be selected to provide sufficient connecting material volume (e.g., the connecting material between cutting rows), and/or to provide an appropriate lever arm to keep removal operations for cutting rows within selected force boundaries (e.g., high enough to avoid inadvertent removal, and low enough to provide for convenient removal). It can be seen that, for embodiments that include and/or are configured to utilize a blade edge removal tool, the spacing distance may be configured to cooperate with the blade edge removal tool—for example providing spacing such that sequential rows engage the removal tool properly and/or consistently, and/or allowing for a greater removal force due to the assistance and predictability provided by the removal tool. 
     Each of the perforations in the rows of perforations  125   a ,  135   a , and  145   a  are selectively sized and shaped to provide, without limitation, one or more of three functions. First, each row of perforations  125   a ,  135   a , and  145   a  forms a breakaway line, which allows the portion of the distal end directly in front of each row of perforations to be cleanly broken away responsive to a twisting force applied orthogonally to the plane of the multi-edge blade  101 . Second, the size and shape of the perforations is selected such that the structural integrity of the multi-edge blade remains intact when the multi-edge saw blade is in use. That is, under use in a sawing or cutting operation, the perforations are sized and shaped such that the saw blade remains rigid (and/or with controlled flexibility), and the outermost cutting edge remains securely attached to the main body of the blade. Third, each perforation is shaped such that after the cutting edge before its row is broken away, the remaining material will form a new row of cutting teeth across the new distal edge of the multi-edge blade. The removal operation is explained in more detail with respect to  FIGS.  2 A and  3 A- 3 C  below. As the example multi-edge blade  101  of  FIG.  1 A  includes three rows of perforations ( 125   a ,  135   a , and  145   a , respectively), the blade effectively includes four separate cutting edges, which can be used sequentially by breaking off (or “snapping off”) each leading cutting edge as it becomes worn or damaged. As will be discussed in more detail with respect to  FIGS.  5 A and  5 B , according aspects of the present disclosure, each cutting edge can be removed from the multi-edge blade without removing the blade from the oscillating tool to which it is attached. 
     The proximate end of the multi-edge saw blade  101  includes an attachment socket  160   a  which can be used to fix or secure the blade to the oscillating drive member of an electric oscillating power tool. Within  FIG.  1 A , the attachment socket  160   a  is depicted as a universal (or “open anchor”) type socket. However, the methods of the present disclosure are not limited in this regard. Indeed, the attachment socket  160   a  can be any type of mounting type including, but not limited to, starlock mount or supercut. Further, while  FIG.  1 A  shows attachment socket  160   a  as offset from the plane of breakaway cutting edges  110   a ,  120   a , and  130   a , aspects of the present disclosure are not limited in this regard. In certain aspects of the present disclosure, the attachment socket and the cutting edges of the blade are located substantially in the same plane in a non-offset configuration. Without limitation to any other aspect of the present disclosure, any type of oscillating tool connection may be utilized in embodiments herein. 
     Looking now to  FIG.  1 B , a second example multi-edge saw blade  102  according to aspects of the present disclosure is depicted. Multi-edge saw blade  102  is formed generally in a plane and includes a first row of cutting teeth  115   b  and two rows of perforations  125   b  and  135   b , as compared to the three rows of perforations within the first example multi-edge saw blade  101  of  FIG.  1 A . Such a configuration provides multi-edge saw blade  102  with two breakaway cutting edges  110   b  and  120   b  and three cutting edges total. As with the multi-edge blade of  FIG.  1 A , the cutting edges of  FIG.  1 B  provide a flat cutting edge, with first row of teeth  115   b  and first and second rows of perforations ( 125   b  and  135   b , respectively) all oriented in straight lines substantially perpendicular to the axis of oscillation  170   b . As with the blade of  FIG.  1 A , multi-edge saw blade  102  also includes an attachment socket  160   b  fixed to its proximate end which can be used to secure the multi-edge blade  102  to the oscillating drive member of an electric oscillating power tool. To this end, multi-edge saw blade  102  includes three usable “flat” blade edges in a single attachment accessory that can be used successively by breaking away a portion of the multi-edge saw blade between each row of perforations and the distal cutting edges as they become worn or damaged without removing the multi-edge saw blade itself from the tool. 
     It should be noted that within aspects of the present disclosure, the number of total cutting edges within a multi-edge saw blade can be any number that best befits the needs of a specific application. For example, a multi-edge saw blade according to aspects of the present disclosure can include only two cutting edges total by including only a single row of perforations. Or, in another example, a multi-edge saw blade according to aspects of the present disclosure could include six cutting edges by including five rows of perforations. Under different aspects of the present disclosure, the number of perforation rows and breakaway cutting edges is selected based on, without limitation, the requirements of a particular application, the material used to fabricate the multi-edge saw blade, the thickness of the multi-edge saw blade, the number of teeth in each cutting edge, the depth of the teeth in each cutting edge, the manufacturing method used to create the rows of perforations, or some combination of these design parameters. Under certain aspects of the present disclosure, a multi-edge saw blade will include “n” rows of perforations and “n+1” cutting edges total, wherein “n” comprises an integer greater than or equal to two. 
     The multi-edge saw blade of the present disclosure can be formed from any suitable material including, but not limited to, high carbon steel, stainless steel, a carbon alloy, carbon fiber, high density polyethylene, poly carbonate, thermoset plastic, high heat epoxy resin, or some combination of these materials. The selection of a material can typically depend on the material that the blade is intended to cut, characteristics of the blade such as sharpness, commercially acceptable wear profiles for the blade, or the like. In particular, a desired material hardness for the multi-edge saw blade may drive the selection of material as different blade hardness values are best suited for cutting different materials. For example, the material used to form the multi-edge saw blade may be selected such that the multi-edge saw blade has a hardness between 42 HRC and 56 HRC (Rockwell Hardness C Scale), inclusive. Or, the material used may be selected such that the multi-edge saw blade has a hardness of about 50 HRC. In certain embodiments, a coating and/or surface treatment may be utilized to adjust the hardness, thermal performance, and/or wear characteristics of the engaging surface of the blade. 
     Further, the thickness of the multi-edge saw blade can be any gauge as best befits the needs of an intended application for a given material selected. For example, the thickness of the saw blade could be within the ranges of 16-26 gauge (0.0187 inches-0.0625 inches), inclusive, 21-25 gauge (0.0219 inches-0.0344 inches), inclusive, or 22-24 gauge (0.025 inches-0.0312 inches), inclusive. In certain applications a lower gauge blade will allow for a smoother cut with less friction and finer control of the cut tolerances. In other applications, however, a thicker blade will provide more strength in the blade, suitable for cutting harder materials. In certain embodiments the blade thickness may be varied along the length and/or across the width of the blade, for example where the mechanical characteristics of the blade are more important than the specific cutting thickness for a given application. Similarly, the number of cutting teeth in each cutting edge and the depth of the cutting teeth (i.e., the length of the individual cutting teeth) are typically selected dependent on the needs of a specific application. For example, a coarse blade having a low number of large teeth may be suitable for an application wherein heavy cutting is required, and/or where fast, coarse cutting of the material is desirable and/or acceptable. In another example, a fine blade having a high number of small teeth may be suitable within an application that requires precision cutting of a relatively soft material. In certain applications, the teeth within each cutting edge have a size and number such that the distance between each tooth does not exceed the overall oscillation movement of the multi-edge saw blade. 
     In addition to the above design considerations, the selection of a material, a thickness, and the number and size of teeth within the cutting edges of the multi-edge saw blade of the present disclosure are also be selected such that breakaway edges can be readily removed when worn or damaged under a twisting force orthogonal to the plane of the saw blade while also remaining securely attached to the blade under an oscillating cutting or sawing operation. In some aspects of the present disclosure, these parameters are also influenced by the size and shape of the perforations in each row of perforations. 
     Additionally, in some aspects of the present disclosure, the multi-edge saw blade is coated to improve thermal performance, reduce friction between the blade and a material being cut, improve resistance to corrosion, improve resistance to chemical exposure, improve resistance to water, adjust the surface hardness of the blade, or some combination of these benefits. Within these aspects of the present disclosure, the multi-edge saw blade can be coated with ceramic, graphene, molybdenum disulfide, polytetrafluoroethylene, fluoropolymer, fluoropolymer with Xylan®, fluorinated ethylene propylene (FEP), or some combination of these materials. In some of these aspects of the present disclosure, the multi-edge saw blade is coated by a hot dipping process wherein the saw blade is submerged in a liquid coating. In other aspects of the present disclosure, the multi-edge saw blade is coated using a spray gun. Further, in some aspects of the present disclosure the multi-edge saw blade undergoes an electroless plating or conversion process wherein the surface layer of the blade material is transformed into a corrosion-resistant surface. For example, a black-oxide process can be used to oxidize the surface of a multi-edge saw blade, rendering the surface microporous and blackened. In certain embodiments, a surface treatment such as peening may be applied to adjust the surface hardness of the blade and/or cutting surfaces of the blade. 
     Referring now to  FIG.  2 A , a multi-edge saw blade  201  formed generally in a plane with a flat blade, three breakaway cutting edges ( 210   a ,  220   a , and  230   a ), and four cutting edges total (similar to multi-edge saw blade  101  of  FIG.  1 A  and discussed in detail above with respect to that figure) is illustrated with first breakaway edge  210   a  removed from the multi-edge saw blade  201 . As discussed with respect to  FIG.  1 A , first breakaway edge  210   a  contains a first row of cutting teeth  215   a . Once this first row of cutting teeth  215   a  becomes worn out or if several of the teeth become damaged during a cutting operation, breakaway edge  210   a  can be readily separated from multi-edge saw blade  201  along a first perforation row. By applying a twisting force orthogonal to the plane of the multi-edge saw blade  201 , the connecting material between the perforations within the first row of perforations break, freeing first breakaway cutting edge  210   a  and rendering first row of perforations into a second row of cutting teeth  225   a , which then form the new distal edge of multi-edge saw blade  201 . In this way, a spent cutting edge (first row of teeth  215   a ) is removed and a second cutting edge is revealed, ready to continue work. Additionally, the second row of perforations  235   a  is available to allow separation of second breakaway cutting edge  220   a  from multi-edge blade  201  and reveal a third cutting edge when the second cutting edge wears out, and the third row of perforations  245   a  is available to subsequently allow separation of third breakaway cutting edge  230   a  and reveal a fourth cutting edge when the third cutting edge wears out. As with multi-edge blade  101  of  FIG.  1 A , multi-edge blade  201  further includes attachment socket  260   a  which can be used to fix or secure the blade to the oscillating drive member of an electric oscillating power tool. In this way, a single oscillating saw accessory attachment (the multi-edge saw blade of the present disclosure) can provide multiple cutting edges which can be subsequently used without removing the accessory attachment from an oscillating tool using the attachment. 
     Looking now to  FIG.  2 B , an example multi-edge saw blade  202  according to the present disclosure is shown that is formed generally in a plane and includes three breakaway cutting edges ( 210   b ,  220   b , and  220   b ) and four cutting edges total wherein all of the cutting edges are rounded. As can be seen from  FIG.  2 B , the cutting teeth in first row of cutting teeth  215   b  are arranged in a curve centered on the axis of oscillation  270   b . Embodiments herein set forth a curve centered on the axis of oscillation  270   b  as an example, but the curve of the blade, where present, may be asymmetrical. Additionally or alternatively, curved blades are depicted with a convex curvature, but the curvature may additionally or alternatively be convex in certain embodiments. In the example of  FIG.  2 B , the second row of cutting teeth  225   b  and third row of perforations  235   b  and fourth row of perforations  245   b  are also arranged into substantially congruent curves, all centered on the axis of oscillation  270   b . Within some aspects of the present application, the cutting teeth and perforations are arranged in arcs that are a section of circle. Within such aspects, these arcs can be any selected portion of a circle, for example 30 degrees of a circle, 60 degrees of a circle, 90 degrees of a circle, 120 degrees of a circle, or some other fraction of a circle. Within such aspects the curve can comprise between 30 degrees and 120 degrees of a circle, inclusive. As with the example multi-edge saw blade  201  of  FIG.  2 A , multi-edge saw blade  202  is depicted with first breakaway cutting edge  210   b  separated from multi-edge saw blade  202 , revealing a second row of cutting teeth  225   b . Second and third rows of perforations ( 235   b  and  245   b , respectively) further provide the ability to separate second breakaway cutting edge  220   b  and third second breakaway cutting edge  230   b  from multi-edge saw blade  202 , providing a third and fourth row of cutting teeth as they are subsequently needed. As with multi-edge blade  101  of  FIG.  1 A , multi-edge blade  202  further includes attachment socket  260   b  which can be used to fix or secure the blade to the oscillating drive member of an electric oscillating power tool. In this way, a single oscillating saw accessory attachment (the multi-edge saw blade of the present disclosure) can provide multiple rounded cutting edges which can be subsequently used without removing the accessory attachment from an oscillating tool using the attachment. 
     Looking now to  FIG.  2 C , an example multi-edge saw blade  203  according to the present disclosure is shown that is formed generally in a plane and includes three breakaway cutting edges ( 210   c ,  220   c , and  220   c ) and four cutting edges total wherein all of the cutting edges are angled. As can be seen from  FIG.  2 C , the cutting teeth in first row of cutting teeth  215   c  are arranged at an angle with respect to the axis of oscillation  270   c . Second row of cutting teeth  225   c  and third row of perforations  235   c  and fourth row of perforations  245   c  are also arranged at substantially the same angle with respect to the axis of oscillation  270   c . Within some aspects of the present disclosure, this angle can be 10 degrees, 20 degrees, 30 degrees, 45 degrees, or any other angle substantially less than 90 degrees. Withing some aspects of the present disclosure, this angle can be between 10 and 45 degrees, inclusive, or between 10 and 60 degrees, inclusive. As with the example multi-edge saw blade  201  of  FIG.  2 A , multi-edge saw blade  203  is depicted with first breakaway cutting edge  210   c  separated from multi-edge saw blade  203 , revealing a second row of cutting teeth  225   c . Second and third rows of perforations ( 235   c  and  245   c , respectively) further provide the ability to separate second breakaway cutting edge  220   c  and third second breakaway cutting edge  230   c  from multi-edge saw blade  203 , providing a third and fourth row of cutting teeth as they are subsequently needed. As with multi-edge blade  101  of  FIG.  1 A , multi-edge blade  203  further includes attachment socket  260   c  which can be used to fix or secure the blade to the oscillating drive member of an electric oscillating power tool. In this way, a single oscillating saw accessory attachment (the multi-edge saw blade of the present disclosure) can provide multiple angled cutting edges which can be subsequently used without removing the accessory attachment from an oscillating tool using the attachment. 
     Looking now to  FIG.  3 A , a dimensional drawing detailing the relative size dimensions of an example multi-edge saw blade  301  according to aspects of the present disclosure is shown. Multi-edge saw blade  301  includes a single row of perforations  325   a  and one breakaway cutting edge  310   a  that includes a first row of cutting teeth  315   a . As described in detail above with respect to  FIGS.  1 A- 1 B and  2 A- 2 C , when breakaway cutting edge  310   a  is removed from multi-edge saw blade  301 , row of perforations  325   a  will be rendered into a second row of cutting teeth. Multi-edge saw blade  301  has an initial length  350   a , running from the proximate edge of the blade to first row of cutting teeth  315   a , and secondary length of  360   a , running from the proximate edge of the blade to the row of perforations  325   a , which become the distal edge of the saw blade when breakaway cutting edge  310   a  is removed. Multi-edge saw blade  301  has a fixed width  370   a  which remains constant before and after the removal of breakaway cutting edge  310   a . Detail  312   a  is represented in  FIG.  3 B  and illustrates an example pair of perforations ( 323   b  and  327   b ) according to the present disclosure, and detail  317   a  is represented in  FIG.  3 C  and illustrates an example pair of cutting teeth ( 333   c  and  337   c ) according to aspects of the present disclosure. 
     Looking to  FIG.  3 B , two perforations  323   b  and  327   b  are shown. As can be seen in  FIG.  3 B , the shape of perforations  323   b  and  327   b  are selected to realize cutting teeth  333   b  and  337   b  and connection elements  343   b ,  347   b , and  349   b . As discussed in detail above with respect to  FIG.  2 A , responsive to a twisting force applied orthogonally to the plane of multi-edge saw blade  301 , connection elements  343   b ,  347   b , and  349   b  break near their narrowest points and form additional cutting teeth while allowing breakaway cutting edge  310   a  to fall away.  FIG.  3 C  illustrates two cutting teeth  333   c  and  337   c  on first row of cutting teeth  315   a . The teeth  333   c  and  337   c  have a tooth depth  340   c  representing the length of each cutting tooth and a tooth spacing  350   c  representing the distance from the tip of one tooth to the next tooth. As described above, in some aspects of the present disclosure, the selection of tooth depth  340   c  and tooth spacing  350   c  is dependent on the needs of a specific application. For example, within an application wherein heavy cutting is required, a relatively large tooth depth  340   c  and a relatively wide tooth spacing  350   c  may be preferable. However, in another example wherein precision cutting is required, a relatively short tooth depth  340   c  and a relatively small tooth spacing  350   c  is preferable. 
     Within aspects of the present disclosure, the multi-edge saw blade can be formed using a plurality of manufacturing processes. For example, the initial row of cutting teeth with a selected tooth depth and tooth spacing (e.g., as detailed in  FIG.  3 C ) and the one or more rows of perforations with a selected size and shape (e.g., as detailed in  FIG.  3 B ) can be formed using a laser cut process, a water jet process, a 3D printing process, a plastic injection molding process, or die stamping. The preferred manufacturing process used to realize the multi-edge saw blade as described throughout the present specification can, in certain aspects of the present disclosure, be dependent on the material used to make the multi-edge saw blade, the quantity of multi-edge saw blades being produced, the degree of precision required to meet preselected design tolerances, and the application in which the multi-edge saw blades will be used. For example, in certain aspects of the present disclosure die stamping may be the preferred fabrication method for multi-edge saw blades made from metal alloys and requiring very high quantities. Or, in other aspects of the present disclosure, plastic injection molding might be more favorable for multi-edge saw blades fabricated from various plastic resins. Further, within aspects of the present disclosure, the number of teeth in each cutting edge, the size of the teeth (i.e., the “tooth depth”) in each cutting edge, and distance between each tooth point (i.e., the “tooth spacing”) in each cutting edge can be selected based on the needs of a particular application for the multi-edge saw blade. For example, one or more of these parameters (tooth number, tooth depth, and tooth spacing) can be selected to provide cutting edges suitable for cutting one of metal, plastic, wood, drywall, food products, or materials relevant to medical applications (e.g., bandages, skin, bone, connective tissue, other soft tissues, etc.). 
     Looking now to  FIG.  3 D , a dimensional drawing detailing the relative size dimensions of an example multi-edge saw blade  302  with rounded cutting edges according to aspects of the present disclosure is shown. Multi-edge saw blade  302  includes a single row of perforations  325   d  and one breakaway cutting edge  310   d  that includes a first row of cutting teeth  315   d . As described in detail above with respect to  FIGS.  1 A- 1 B and  2 A- 2 C , when breakaway cutting edge  310   d  is removed from multi-edge saw blade  302 , row of perforations  325   d  will be rendered into a second row of cutting teeth. Multi-edge saw blade  302  has an initial length  350   d , running from the proximate edge of the blade to the tip of the center tooth on the first row of cutting teeth  315   d , and secondary length of  360   d , running from the proximate edge of the blade to the front of the center perforation within row of perforations  325   d , which become the distal edge of the saw blade when breakaway cutting edge  310   d  is removed. Multi-edge saw blade  302  has a fixed width  370   d  which remains constant before and after the removal of breakaway cutting edge  310   d . Detail  312   d  is represented in  FIG.  3 E  and illustrates three example perforations ( 323   e ,  327   e , and  329   e ) according to the present disclosure, and detail  317   d  is represented in  FIG.  3 F  and illustrates an example pair of cutting teeth ( 333   f  and  337   f ) according to aspects of the present disclosure. 
     Looking to  FIG.  3 E , three perforations  323   e ,  327   e , and  329   e  are shown. As can be seen in  FIG.  3 E , the shape of perforations  323   e ,  327   e , and  329   e  are selected to realize connection elements  341   e ,  343   e ,  347   e , and  349   e . As discussed in detail above with respect to  FIG.  2 A , responsive to a twisting force applied orthogonally to the plane of multi-edge saw blade  302 , connection elements  341   e ,  343   e ,  347   e , and  349   e  break near their narrowest point and form additional cutting teeth while allowing breakaway cutting edge  310   d  to fall away.  FIG.  3 F  illustrates two cutting teeth  333   f  and  337   f  on first row of cutting teeth  315   d . The teeth  333   f  and  337   f  have a tooth depth  340   f  representing the length of each cutting tooth and a tooth spacing  350   f  representing the distance from the tip of one tooth to the next tooth. As described above, in some aspects of the present disclosure, the selection of tooth depth  340   f  and tooth spacing  350   f  is dependent on the needs of a specific application. For example, within an application wherein heavy cutting is required, a relatively large tooth depth  340   f  and a relatively wide tooth spacing  350   f  would be preferable. However, in another example wherein precision cutting is required, a relatively short tooth depth  340   f  and a relatively small tooth spacing  350   f  is preferable. 
     Looking now to  FIG.  3 G , a dimensional drawing detailing the relative size dimensions of an example multi-edge saw blade  303  with angled cutting edges according to aspects of the present disclosure is shown. Multi-edge saw blade  303  includes a single row of perforations  325   g  and one breakaway cutting edge  310   g  that includes a first row of cutting teeth  315   g . As described in detail above with respect to  FIGS.  1 A- 1 B and  2 A- 2 C , when breakaway cutting edge  310   g  is removed from multi-edge saw blade  303 , row of perforations  325   g  will be rendered into a second row of cutting teeth. Multi-edge saw blade  303  has an initial length  350   g , running from the proximate edge of the blade to the tip of the furthest tooth on the first row of cutting teeth  315   g , and secondary length of  360   g , running from the proximate edge of the blade to the front of the furthest perforation within row of perforations  325   g , which becomes the distal edge of the saw blade when breakaway cutting edge  310   g  is removed. Multi-edge saw blade  303  has a fixed width  370   g  which remains constant before and after the removal of breakaway cutting edge  310   g . Detail  312   g  is represented in  FIG.  3 H  and illustrates two example perforations ( 323   h  and  327   h ) according to methods of the present disclosure, and detail  317   g  is represented in  FIG.  3 F  and illustrates three example cutting teeth ( 333   i ,  337   i , and  339   i ) according to aspects of the present disclosure. 
     Looking to  FIG.  3 H , two perforations  323   h  and  327   h  are shown. As can be seen in  FIG.  3 H , the shape of perforations  323   h  and  327   h  are selected to realize connection elements  343   h ,  347   h , and  349   h . As discussed in detail above with respect to  FIG.  2 A , responsive to a twisting force applied orthogonally to the plane of multi-edge saw blade  303 , connection elements  343   h ,  347   h , and  349   h  break near their narrowest point and form additional cutting teeth while allowing breakaway cutting edge  310   g  to fall away.  FIG.  3 I  illustrates three cutting teeth  333   i ,  337   i , and  339   i  on first row of cutting teeth  315   g . The teeth  333   i ,  337   i , and  337   i  have a tooth depth  340   i  representing the length of each cutting tooth and a tooth spacing  350   i  representing the distance from the tip of one tooth to the next tooth. As described above, in some aspects of the present disclosure, the selection of tooth depth  340   i  and tooth spacing  350   i  is dependent on the needs of a specific application. For example, within an application wherein heavy cutting is required, a relatively large tooth depth  340   i  and a relatively wide tooth spacing  350   i  may be preferable. However, in another example wherein precision cutting is required, a relatively short tooth depth  340   i  and a relatively small tooth spacing  350   i  may be preferable. 
       FIG.  4 A  shows a perspective drawing of an example blade edge removal tool  410  according to the present disclosure. In some aspects of the present disclosure, a blade edge removal tool  410  can be used to assist a user in removing a worn or damaged breakaway blade edge from a multi-edge saw blade. Blade edge removal tool  410  includes a bracing member  417  connected to a snapping member  415  at pivot points  413  (only one pivot point is visible in  FIG.  4 A ). A confirmation slot  440  is situated between bracing member  417  and snapping member  415  to permit a user to align and visibly confirm the placement of a perforation row of a multi-edge blade within the blade removal tool  410 . A separate slot (not visible in  FIG.  4 A ) wide and tall enough to permit passing of a multi-edge saw blade runs through bracing member  417  and aligns with a similar slot  422  in snapping member  415 . Looking now to  FIG.  4 B , blade edge removal tool  410  is positioned over a multi-edge saw blade  430  according to the present disclosure through the slot in bracing member  417  (not visible in  FIG.  4 B ) and slot  422  in snapping member  415 . As can be seen in  FIG.  4 B , blade edge removal tool  410  is positioned such that the row of perforations nearest the distal edge of multi-edge saw blade  430  is situated in the confirmation slot  440  between bracing member  417  and snapping member  415 , with the leading breakaway cutting edge at least partially inside slot  422 . Looking now to  FIG.  4 C , with bracing member  417  held in place, snapping member  415  is rotated about pivot points  413  (again, only one of the pivot points  413  is visible in  FIG.  4 C ). This rotation provides a twisting, downward force on the breakaway cutting edge within slot  422 . Responsive to this force, the connecting material between the perforations break (as described with respect to  FIGS.  3 A- 3 B ), freeing the leading breakaway cutting edge from multi-edge saw blade  430  and realizing a new cutting edge across the new distal edge of multi-edge saw blade  430 . Looking finally to  FIG.  4 D , with the worn or damaged breakaway cutting edge removed, the blade edge removal tool  410  is removed from multi-edge saw blade  430 , leaving it ready to continue operating with a fresh cutting edge,  435 . 
     It should be noted that while blade edge removal tool  410  can be used in certain applications to aid a user in removing a worn or damaged breakaway blade edge, not all applications require such a specialized tool to remove worn or damaged breakaway blade edges. Indeed, in certain applications, a worn or damaged breakaway blade edge can be removed using a standard tool, such as, but not limited to, a pair of pliers. In certain applications, the blade edge removal tool  410 , as depicted in  FIGS.  4 A- 4 D  can be a convenience option, providing users with a small and efficient tool for rapidly removing spent breakaway blade edges. In other applications, the blade edge removal tool can be a necessary tool for effectively removing spent breakaway blade edges. In certain applications, it may be desirable that the blade can be operated without a removal tool, for example applications in confined spaces or limited access, where the number of tools to be carried by the operator will be minimized. It can be seen that the blade edge removal tool  410  provides for convenient blade removal with a reduced risk of damage to the blade, injury of the user, consistently applied removal force, enhanced removal force distributed across the width of the blade, and/or ease in capturing the removed cutting tooth row (e.g., to ensure proper disposal). Accordingly, the removal tool, where present, enhances the convenience and efficiency provided by the blade, and/or allows for blade configurations that would otherwise be unavailable—for example a blade designed for use with a removal tool may allow for a greater removal force, thicker blade, stiffer blade, and/or a blade with a greater mechanical strength profile. 
     Looking now to  FIG.  5 A , a multi-edge saw blade  530  according to aspects of the present disclosure is shown attached to an oscillating tool  510 . Within  FIG.  5 A , a break away cutting edge  535  is shown being removed from multi-edge saw blade  530  without the blade  530  being disengaged from the tool  510 . As can be seen in  FIG.  5 B , immediately subsequent to the removal of breakaway cutting edge  535 , multi-edge saw blade  530  is ready to continue sawing or cutting operations with a fresh cutting edge across its distal edge. In this way, as described throughout the present disclosure, the multi-edge saw blade  530  provides a saw blade for an oscillating tool  510  that includes multiple cutting edges that can be used sequentially without ever disengaging or otherwise removing the blade  530  from the tool. 
     Referencing  FIG.  6   , an example procedure  600  includes an operation  610  to cut a material with a first blade of an oscillating tool having a multi-edge saw blade, an operation  620  to remove the first blade, and an operation  630  to cut the material with a second blade of the oscillating tool. Looking to  FIG.  7   , a second example procedure  700  includes an operation  710  to cut a material with a first blade of an oscillating tool having a multi-edge saw blade, an operation  720  to remove the first blade by applying a perpendicular twisting force and separating the first blade at a perforating line interposed between the first blade and the second blade, and an operation  730  to cut the material with a second blade of the oscillating tool. Looking to  FIG.  8   , a third example procedure  800  includes an operation  810  to cut a material with a first blade of an oscillating tool having a multi-edge saw blade, an operation  820  to remove the first blade comprising a sub-operation  823  to insert the multi-edge saw blade into a blade edge removal tool at a selected depth, aligning the perforating line with a confirmation slot on the blade edge removal tool followed by a sub-operation  827  to rotate a snapping member of the blade edge removal tool and thereby separate the first blade from the multi-edge saw blade at a perforating line interposed between the first blade and the second blade, and an operation  830  to cut the material with a second blade of the oscillating tool. The example procedures of  FIGS.  6 ,  7 , and  8    may be performed using any tool and/or multi-edge blade as described throughout the present specification. 
     Some aspects of the present disclosure provide a kit that includes a multi-edge blade according to aspects of the present disclosure and a blade edge removal tool. Elements of the kit may be embodied in any of the tools or blades as set forth throughout the present specification. As described in detail within the discussions of  FIG.  1 A- 1 B ,  2 A- 2 C, and  3 A- 3 I above, the multi-edge blade within the kit comprises a plurality of rows of cutting teeth with a corresponding perforating line interposed between each adjacent row of cutting teeth. The kit further includes a blade edge removal tool according to aspects of the present disclosure. As described in detail with respect to  FIGS.  4 A- 4 D  above, the blade edge removal tool comprises a bracing member having a slot configured to permit the passing of a multi-edge blade through the bracing member. The blade edge removal tool further comprises a snapping member pivotally coupled to the bracing member and configured to apply a perpendicular twisting force to the multi-edge blade in response to a pivoting motion of the snapping member. In some aspects of the present disclosure, the blade edge removal tool within the kit further includes a confirmation slot interposed between the bracing member and the snapping member. Within such aspects the confirmation slot comprises a shape corresponding to the shape of each perforating line of the multi-edge blade. For example, if the kit includes a multi-edge blade with a flat edge, with rows of teeth and perforations oriented in straight lines substantially perpendicular to an intended axis of oscillation, then the confirmation slot will also be oriented in a straight line substantially perpendicular to the intended axis of oscillation. In other examples, for multi-edge blades that are curved, as shown, for example, in  FIGS.  2 B and  3 D , the confirmation slot will also be curved to match the shape of the rows of teeth and perforations, and for multi-edge blades that are angled, as shown, for example, in  FIGS.  2 C and  3 G , the confirmation slot will also be angled to match the shape of the rows of teeth and perforations. 
       FIG.  9    shows a perspective drawing of an example blade edge removal tool  910  according to the present disclosure having a curved confirmation slot  940  and suitable for use with a curved multi-edge blade according to aspects of the present disclosure. In some aspects of the present disclosure, a blade edge removal tool  910  can be used to assist a user in removing a worn or damaged breakaway blade edge from a curved multi-edge saw blade. Blade edge removal tool  910  includes a bracing member  917  connected to a snapping member  915  at pivot points  913  (only one pivot point is visible in  FIG.  9   ). A confirmation slot  940  is situated between bracing member  917  and snapping member  915  to permit a user to properly align a perforation row of a multi-edge blade into the blade removal tool  910 . A separate slot (not visible in  FIG.  9   ) wide and tall enough to permit passing of a multi-edge saw blade runs through bracing member  917  and aligns with a similar slot  922  in snapping member  915 . 
       FIG.  10    shows a perspective drawing of an example blade edge removal tool  1010  according to the present disclosure having an angled confirmation slot  1040  and suitable for use with an angled multi-edge blade according to aspects of the present disclosure. In some aspects of the present disclosure, a blade edge removal tool  1010  can be used to assist a user in removing a worn or damaged breakaway blade edge from an angled multi-edge saw blade. Blade edge removal tool  1010  includes a bracing member  1017  connected to a snapping member  1015  at pivot points  1013  (only one pivot point is visible in  FIG.  10   ). A confirmation slot  1040  is situated between bracing member  1017  and snapping member  1015  to permit a user to properly align a perforation row of a multi-edge blade into the blade removal tool  1010 . A separate slot (not visible in  FIG.  10   ) wide and tall enough to permit passing of a multi-edge saw blade runs through bracing member  1017  and aligns with a similar slot  1022  in snapping member  1015 . 
     While the disclosure has been disclosed in connection with the preferred embodiments shown and described in detail, various modifications and improvements thereon will become readily apparent to those skilled in the art. Accordingly, the scope of the present disclosure is not to be limited by the foregoing examples, but is to be understood in the broadest sense allowable by law.
