Description:
CROSS-REFERENCE TO RELATED PATENT APPLICATIONS 
     This application claims the benefit of and priority to U.S. Provisional Patent Application No. 63/278,945, filed Nov. 12, 2021, the entire disclosure of which is incorporated by reference herein. 
    
    
     BACKGROUND 
     Concrete roadways are often exposed to extreme environmental conditions including heat, cold, precipitation, and other various elements. Conventional concrete roadways and sidewalks typically include different types of joints, such as longitudinal and traverse joints, to control cracking and prevent excess stresses from developing. In some circumstances, excessive heat, cold, or precipitation may cause portions of concrete roadways to heave at the joints. Relief cuts in concrete roadways may reduce such heaving by allowing a wider space for the concrete to expand in hot temperatures and retract in cold temperatures. However, conventional cutting devices do not provide means for creating relief cuts of equal depth at equal distances from one another, which can cause stress points to form in the roadways. Accordingly, it would be advantageous to provide a cutting device to simultaneously create a plurality of equal relief cuts in concrete roadways at various locations between the joints to allow for extra space for the concrete to expand and retract with varying temperatures. 
     SUMMARY 
     One embodiment of the present disclosure relates to a roadway cutting device. The roadway cutting device can include a shaft that extends laterally between a first end and a second end. The roadway cutting device can include a first blade coupled to the shaft at a first location along the shaft and a second blade coupled to the shaft at a second location along the shaft. The roadway cutting device can include a spacer disposed between the first blade and the second blade. The first blade and the second blade can rotate simultaneously at the same rotational speed. 
     Another embodiment of the present disclosure relates to a roadway cutting device. The roadway cutting device can include a hexagonal shaft that extends between a first end and a second end. The roadway cutting device can include a stopper coupled to the first end of the hexagonal shaft. The stopper can facilitate coupling the hexagonal shaft to a portion of a machine. The roadway cutting device can include a plurality of blade sets each having a plurality of blades coupled to the hexagonal shaft by a connector assembly. The roadway cutting device can include a plurality of spacers slidably coupled to the hexagonal shaft. A first subset of the plurality of spacers is disposed between a first blade and a second blade of a first blade set. A second subset of the plurality of spacers is disposed between the first blade of the first blade set and a third blade of a second blade set. 
     Another embodiment of the present disclosure relates to a method of manufacturing a roadway cutting device. The method can include providing a hexagonal shaft extending between a first end having a first stopper and a second end free from the first stopper. The method can include sliding a first subset of spacers along the hexagonal shaft from the second end toward the first end. The method can include sliding a first connector along the hexagonal shaft from the second end toward the first end such that the first connector engages with a portion of the first subset of spacers. The method can include sliding a first blade along the hexagonal shaft from the second end toward the first end such that the first blade at least partially engages with the first connector. The method can include sliding a first connector cap along the hexagonal shaft from the second end toward the first end such that the first connector cap engages with a portion of the first blade. The method can include sliding a second subset of spacers along the hexagonal shaft from the second end toward the first end. The method can include sliding a second connector along the hexagonal shaft from the second end toward the first end such that the second connector engages with a portion of the second subset of spacers. The method can include sliding a second blade along the hexagonal shaft from the second end toward the first end such that the second blade at least partially engages the second connector.

     DETAILED DESCRIPTION 
     Before turning to the figures, which illustrate the exemplary embodiments in detail, it should be understood that the present application is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting. 
     According to an exemplary embodiment, a roadway cutting device is shown. In various embodiments, the roadway cutting device may be used to create relief cuts (e.g., slots) in various roadways including, but not limited to, concrete roads, sidewalks, bridges, or the like. The roadway cutting device may include a plurality of blade sets, each including one or more blades. The blade sets may each couple to a portion of a shaft of the roadway cutting device, such as a hex shaft. The roadway cutting device may include several spacers positioned in between each blade set or one or more blades of the blade sets, such that each blade set is positioned a predetermined distance between one another along the shaft (e.g., 1 millimeter apart, 10 millimeters apart, 100 millimeters apart, 500 millimeters apart, etc.). 
     The roadway cutting device may include one or more stoppers positioned at an end portion of the shaft to facilitate maintaining the spacers and blade sets in place. The stoppers may facilitate coupling the shaft to a portion of a machine, such as a skid-steer loader with hydraulic capacity or another machine. The roadway cutting device may be configured to create several cuts of equal depths into a roadway. In some embodiments, each cut may be equidistant in relation to another. In some embodiments, at least two cuts may be equidistant in relation to another. In some embodiments, each cut may be positioned at various distances in relation to one another. The roadway cutting device may operably couple to one or more motors configured to rotate each blade of the blade sets. Each blade of the blade sets may rotate at a same rotational speed for a predetermined amount of time (e.g., 1 second, 10 seconds, 100 seconds, etc.) to create a plurality of equally sized (e.g., in depth, width, etc.) relief cuts. 
     According to the exemplary embodiment depicted in  FIG.  1   , a roadway cutting device  100  is shown. In various embodiments, the roadway cutting device  100  is configured to couple (e.g., via structure  90  and machine attachment  94 ) to a portion of machinery  1002  (as shown in  FIG.  10   ), such as construction machinery including, but not limited to, a skid-steer loader with hydraulic capacity. In various embodiments, the roadway cutting device  100  is configured to couple to a portion of various other on-road or off-road vehicles or machinery, such as a semi-truck, a bus, farming machinery, or the like. While the exemplary embodiment shown throughout the figures is generally shown coupled to a machine attachment  94 , it should be noted that the roadway cutting device  100  may be configured to couple to machinery through various other attachment fixtures. 
     As shown in  FIG.  1 - 4   , the roadway cutting device  100  can include a shaft, shown as shaft  302 . According to an exemplary embodiment, the shaft  302  is a standard hexagonal shaft. In various other embodiments, the shaft  302  may include various other rod shapes including, but not limited to, cylindrical, square, asymmetrical, a combination thereof, or another shape. According to an exemplary embodiment, the shaft  302  is uniform in diameter extending from a first end  402  to a second end  404 . In various other embodiments, the shaft  302  may vary in diameter, shape, or size. In various embodiments, the shaft  302  may include one or more threaded portions. In various embodiments, the shaft  302  is made of a metallic material. For example, the shaft  302  may be made of steel. 
     In various embodiments, the cutting device  100  includes one or more stoppers  304  to facilitate coupling the shaft  302  to a portion of machinery (as shown by machine attachment  94 ). For example, the stopper  304  may be configured to couple with an end portion of the shaft  302  (e.g., second end  404 ) and a portion of the machinery, as shown in  FIG.  3   . As shown in  FIG.  3   , the stopper  304  may include a first opening  306  to receive an end portion of the shaft  302 . In various embodiments, the first opening  306  may have a shape corresponding to the shape of the shaft  302  (e.g., a hexagonal opening) such that the stopper  304  does not rotate relative to the shaft  302  when the stopper  304  is coupled to the shaft  302  (e.g., when the first opening  306  receives the shaft  302 ). In various embodiments, a maximum width of the first opening  306  (e.g., a cross-sectional dimension of the opening  306 ) may be about equal to or slightly larger than the largest width of the shaft  302  (e.g., a cross-sectional dimension of the hex shaft) such that the shaft  302  engages with the first opening  306  of the stopper  304  when the stopper  304  receives a portion of the shaft  302 . For example, an end portion of the shaft  302  may be configured to be press-fitted into a portion of the first opening  306 . In various embodiments, the first opening  306  varies in size or shape to facilitate engaging with the end portion of the shaft  302 . 
     According to an exemplary embodiment, the stopper  304  includes a second opening  308  to receive a portion of machinery (e.g., machine attachment  94 ). In various embodiments, the second opening  308  may be positioned opposite the first opening  306 , as shown in  FIG.  3   . The second opening  308  of the stopper  304  may be configured to receive a portion of the machine attachment  94 , such as a shaft, rod, projection, or other component. The second opening  308  may vary in size or shape to receive a portion of the machinery. In various embodiments, the second opening  308  may receive a portion of a motor assembly operably coupled to the machinery and configured to rotate the shaft  302 , as described in greater detail herein. 
     According to an exemplary embodiment, the stopper  304  is machined from steel, such as carbon steel. In various embodiments, the stopper  304  may be manufactured through various processes including, but not limited to, milling, lathing, laser cutting, water jetting, additive manufacturing techniques, or other techniques. 
     The roadway cutting device  100  may include one or more blade sets  104 . For example, the blade sets  104  may include at least one blade  202  (e.g., shown as first blade  202   a  and second blade  202   b  in  FIGS.  2 - 4   ). According to an exemplary embodiment, each blade set  104  includes two blades  202  (e.g., first blade  202   a  and second blade  202 b). In various other embodiments, each blade set  104  may include more or less blades  202 . In various embodiments, each blade set  104  may include a different number of blades  202  (e.g., a first blade set  104  includes two blades  202 , a second blade set  104  includes one blade  202 , etc.) 
     In various embodiments, each blade set  104  may be at least partially covered by a portion (e.g., cover  114 ) of the machine or machine attachment  94 , as shown in  FIG.  1   . For example, the cover  114  may surround a portion of each blade  202  of the blade set  104  such that, during operation of the cutting device  100  (e.g., while each blade of the blade set  104  is rotating), the cover  114  may facilitate preventing debris (e.g., dirt, dust, fluid, etc.) from expelling from the blades  202  of each blade set  104 . 
     In various embodiments, each blade set  104  may be positioned a specified distance apart from one another along the shaft  302  (e.g., a first blade of a first blade set  104  positioned apart from a first blade of a second blade set  104 ). For example, the roadway cutting device  100  may include at least one spacer  106  positioned along or otherwise coupled to the shaft  302  in between two or more blade sets  104 , as shown throughout the figures. In some embodiments, the device  100  may include a plurality of spacers  106  positioned along or otherwise coupled to the shaft  302  in between two or more blade sets  104 . In some embodiments, the device  100  may include one spacer  106  positioned along the shaft  302  in between two blade sets  104 . According to an exemplary embodiment, each spacer  106  of the plurality of spacers  106  is the same size, dimension, and shape. In various other embodiments, the spacers  106  may vary in size, shape, or dimension. 
     According to an exemplary embodiment, each blade set  104  is positioned at a predetermined distance from one another. For example, as shown in  FIGS.  1 - 3   , a predetermined number of spacers  106  may be disposed between a first blade set  104  and a second blade set  104  positioned along the shaft  302 . By way of example, the cutting device  100  may include sixteen spacers  106  disposed along the shaft  302  between two blade sets  104  (e.g., between a first blade of a first blade set and a first blade of a second blade set). In various other examples, the cutting device  100  may include more or less spacers  106  such that the blade sets  104  are spaced closer to or further apart from one another. 
     The spacers  106  can vary in size or shape depending on the application. By way of example, sixteen spacers  106  each having a width of about 15.6 millimeters (e.g., laterally along the shaft) provides a set distance of 250 millimeters between two blades  202  along the shaft  302 . According to another example, three spacers  106  each having a width of about 10 millimeters provides a set distance of 30 millimeters between two blades  202  along the shaft. These examples are for illustrative purposes only and are in no way limiting to the present disclosure. In various embodiments, each spacer  106  may be significantly smaller (e.g., 1 mm) or significantly larger (e.g., 250 mm) than the above examples. 
     In various embodiments, each blade  202  of the blade set  104  may be positioned a specified distance apart from one another along the shaft  302 . For example, the spacers  106  may be disposed between a first blade  202   a  of a blade set  104  and a second blade  202   b  of the same blade set  104 . In various embodiments, the spacers  106  positioned between each blade  202  may be the same as the spacers  106  positioned between each blade set  104 . In various other embodiments, the spacers  106  positioned between each blade  202  may differ (e.g., in size, shape, dimension, etc.) from the spacers  106  positioned between each blade set  104 . By way of example, the roadway cutting device  100  may include three spacers  106  disposed along the shaft  302  between a first blade  202   a  and a second blade  202   b  of a blade set  104 . In various other examples, the blade set  104  may include more or less spacers disposed between each blade  202 . 
     By way of non-limiting example, a first blade (e.g., blade  202   a  shown in  FIG.  5   ) is positioned at a first location along the shaft  302 , a second blade (e.g., blade  202   b  shown in  FIG.  5   ) is positioned at a second location along the shaft  302 , a third blade (e.g., blade  202   c  shown in  FIG.  5   ) is positioned at a third location along the shaft  302 , and a fourth blade (e.g., blade  202   d  shown in  FIG.  5   ) is positioned a fourth location along the shaft  302 . As shown in the embodiment illustrated in  FIG.  5   , the first blade  202   a  and the second blade  202   b  are spaced a first lateral distance apart along the shaft  302 , while the first blade  202   a  and the third blade  202   c  are spaced a second lateral distance apart along the shaft  302  that is greater than the first distance (e.g., more spacers  106  disposed between the first blade  202   a  and the third blade  202   c  than between the first blade  202   a  and the second blade  202   b ). The third blade  202   c  and the fourth blade  202   d  can be positioned the first lateral distance apart along the shaft  302  (e.g., the same distance between the first blade  202   a  and the second blade  202   b , the same amount of spacers between the first blade  202   a  and the second blade  202   b , etc.). The second blade  202   b  and the fourth blade  202   d  can be positioned the second lateral distance apart along the shaft  302  (e.g., the same distance between the first blade  202   a  and the third blade  202   c , the same amount of spacers, etc.). While the exemplary embodiments shown in the figures include a plurality of equally-sized spacers  106 , the device  100  may alternatively or additionally include a first spacer  106  of a first size and a second spacer  106  of a second size to position each blade  202  as described. 
     The spacers  106  may couple to the shaft through various means. According to an exemplary embodiment, each spacer  106  includes a through-hole (e.g., aperture, opening, slot, etc.) positioned at approximately a center portion of the spacer  106 , as shown in the cross-sectional view of the cutting device  100  in  FIG.  5   . In various embodiments, each spacer  106  includes a cylindrical shape. In such embodiments, the through-hole may be positioned near a center point of an annular face of the spacer  106 , as shown throughout the figures. 
     In various embodiments, the through-hole of the spacer  106  is the same shape as the shaft  302  (e.g., a hexagonal hole), such that the spacer  106  does not rotate relative to the shaft  302  when the spacer  106  is coupled to the shaft  302 . In various embodiments, the through-holes of each spacer  106  are approximately the size of the shaft  302  (e.g., the hexagonal perimeter of the through-hole is just slightly larger than the hexagonal perimeter of the shaft  302 ) such that the shaft  302  can receive the spacer  106  by the through-hole (e.g., the spacer  106  slides onto the shaft  302  from the first end  402  or the second end  404 ). 
     In various embodiments, the spacers  106  are slidably coupled to the shaft  302  such that the spacers  106  can move laterally along the shaft from the first end  402  to the second end  404  or from the second end  404  to the first end  402 . In various other embodiments, the spacers  106  may rigidly couple to the shaft  302  either during or after manufacturing of the cutting device  100 . For example, the spacers  106  may be fastened to the shaft  302  via one or more techniques including, but not limited to, fasteners, welding, adhesives, or other similar mechanisms. 
     The spacers  106  may be made of various materials. According to an exemplary embodiment, the spacers  106  are laser-cut steel. In various other embodiments, the spacers  106  may be made of another metallic material including, but not limited to, aluminum, brass, copper, or the like. In various embodiments, the spacers  106  may include a non-metallic material including plastic, resins, or the like. In various embodiments, the spacers  106  may be manufactured through various means including milling, lathing, water jetting, forging, additive manufacturing, or the like. 
     According to an exemplary embodiment, each blade  202  is coupled to the shaft  302  by a connector assembly  108 . For example, the connector assembly  108  may include a connector base  502  and a connector cap  504 , as shown in  FIGS.  5  and  6   , and among others. In various embodiments, the connector base  502  includes a through-hole to slidably couple to the shaft  302 . In various embodiments, the through-hole of the connector base is the same shape as the shaft  302  (e.g., a hexagonal hole), such that the connector base  502  does not rotate relative to the shaft  302  when the connector base  502  is coupled to the shaft  302 . For example, the through-hole of the connector base  502  may be about equal to the size of the shaft  302  (e.g., the hexagonal perimeter of the through-hole is slightly larger than the hexagonal perimeter of the shaft  302 ) such that the connector base  502  can slide along the shaft  302  (e.g., from the first end  402  to the second end  404 ). 
     In various embodiments, the connector base  502  includes a bearing projection  602  to engage with a portion of the blade  202 , as shown in  FIG.  6   . For example, the blade  202  may include a through-hole positioned at approximately the center of the blade  202  to slidably couple to the shaft  302  through the bearing projection  602 , as shown throughout the figures. For example, the bearing projection  602  may surround a portion of the shaft  302 . In some embodiments, the bearing projection  602  may include one or more components that fix the bearing projection  602  relative to the shaft  302  such that the bearing projection  602  does not rotate relative to the shaft  302  when the connector base  502  is coupled to the shaft  302 . For example, in various embodiments, the through-hole of the blade  202  is the same shape as the shaft  302  (e.g., a hexagonal hole), such that the blade  202  does not rotate relative to the shaft  302  when the blade  202  is coupled to the shaft  302 . The through-hole of the blade  202  may be about equal to the size of the bearing projection  602  (e.g., the hexagonal perimeter of the through-hole is slightly larger than the outer hexagonal perimeter of the bearing projection  602 ) such that the connector cap  504  can slide along the shaft  302  (e.g., from the first end  402  to the second end  404 ) and overlap a portion of the outer hexagonal perimeter of the bearing projection  602 . 
     Similarly, in various embodiments, the connector cap  504  can include a through-hole to slidably couple to the shaft  302  through the bearing projection  602 . In various embodiments, the through-hole of the connector cap  504  is the same shape as the shaft  302  (e.g., a hexagonal hole), such that the connector cap  504  does not rotate relative to the shaft  302  when the connector cap  504  is coupled to the shaft  302 . For example, the through-hole of the connector cap  504  may be about equal to the size of the bearing projection  602  (e.g., the hexagonal perimeter of the through-hole is slightly larger than the outer hexagonal perimeter of the bearing projection  602 ) such that the connector cap  504  can slide along the shaft  302  (e.g., from the first end  402  to the second end  404 ) and overlap a portion of the outer hexagonal perimeter of the bearing projection  602 . 
     In various embodiments, the connector assembly  108  is configured such that the connector base  502  engages with a first side of a blade  202  and the connector cap  504  engages with an opposing second side of the same blade  202 , as shown throughout the figures. For example, as discussed in greater detail below, during manufacturing of the cutting device  100 , the connector base  502  can first slide onto the shaft  302  by the through-hole of the connector base  502  (e.g., from the second end  404  toward the first end  402 ). The blade  202  could then slide along the shaft  302  by the through-hole of the blade  202  (e.g., from the second end  404  toward the first end  402 ) until the blade at least partially engages the connector base  502  (e.g., a portion of a first side of the blade  202  is flush with a portion of the connector base  502 ). Then, the connector cap  504  can slide along the shaft  302  by the through-hole of the connector cap  504  (e.g., from the second end  404  toward the first end  402 ) until the connector cap  504  at least partially engages with a portion of the connector base  502  or the blade  202  (e.g., a portion of a second side opposing the first side of the blade  202  is flush with a portion of the connector cap  504 ). In this configuration, the blade  202  is disposed between the connector base  502  and the connector cap  504 . 
     In various embodiments, the connector assembly  108  includes one or more fasteners to facilitate coupling the connector base  502 , the blade  202 , and the connector cap  504  to one another. As shown in  FIG.  6   , the connector base  502 , the blade  202 , and the connector cap  504  can each include an aperture  604  for receiving a portion of a fastener. By way of example, the aperture  604  can receive a hardened bolt, screw, or other fastener. One or more nuts can couple to the fastener to further facilitate coupling the connector base  502 , the blade  202 , and the connector cap  504  with one another. For example, a hardened bolt can extend within the aperture  604  from the connector cap  504  toward the connector base  502  (or vice versa). A nut can then couple to a portion of the bolt adjacent the connector base  502  such that the connector base  502 , the blade  202 , and the connector cap  504  are rigidly joined. In such configuration, the connector base  502 , the blade  202 , and the connector cap  504  can rigidly join and couple to the shaft  302  such that rotation of the shaft  302  causes rotation of the connector base  502 , the blade  202 , and the connector cap  504 . 
     According to an exemplary embodiment, the roadway cutting device  100  includes four blade sets  104 , as shown throughout the figures. In various other embodiments, the roadway cutting device  100  may include more or less blade sets  104 . For example, the roadway cutting device  100  may include one blade set  104 . The roadway cutting device  100  may include two blade sets  104 , as another example. The roadway cutting device  100  may include three blade sets  104 , as yet another example. In various examples, the roadway cutting device  100  may include four or more than four blade sets  104 . 
     In various embodiments, the connector base  502  or the connector cap  504  are made from various metallic materials including, but not limited to, steel, aluminum, brass, copper, or the like. In various embodiments, the connector base  502  or the connector cap  504  are made from a combination of various metallic and non-metallic material including plastic, resins, or the like. In various embodiments, from various subtractive manufacturing methods including lathing, milling, or other similar machining methods. 
     In various embodiments, the blades  202  are made of a combination of various metallic and non-metallic materials. For example, the blades  202  may be made from a combination of various metals including, but not limited to, steel, aluminum, brass, copper, or the like. In various embodiments, the blades  202  may include one or more additional hardening features. For example, the blades  202  may include a diamond coating surrounding an edge portion (e.g., away from the shaft). In various embodiments, the blades  202  may include another material to facilitate extending the lifecycle of the blade (e.g., by reducing fatigue stress, etc.). 
     In various embodiments, each blade set  104 , connector assembly  108 , or spacer  106  may be configured to rotate simultaneously upon rotation of the shaft  302 . For example, a motor assembly may operably couple to the shaft  302  to cause the shaft  302  to rotate. In various embodiments, the shaft  302  may operably couple to two motor assemblies (e.g., a first motor coupled proximate the first end  402  of the shaft  302  and a second motor coupled proximate the second end  404  of the shaft  302 .) For example, as discussed above, a first motor shaft may operably couple to a first stopper  304  disposed at the first end  402  of the shaft  302  (e.g., via the second opening  308 ). A second motor shaft may operably couple to a second stopper  304  disposed at the second end  404  of the shaft (e.g., via the second opening  308 ). 
     In various embodiments, the motors may be configured to run in series relative to one another. For example, each motor operably coupled to the first end  402  and the second end  404  of the shaft  302  may be configured to run at the same rotational speed, time, or duration, to cause the shaft  302  to rotate at higher levels of torque (e.g., compared to using only one motor). Various types of motors may be configured to rotate the shaft  302 . For example, one or more electric motors, gas motors, diesel motors, hydraulic motors, pneumatic motors, or the like may operably couple to the shaft  302  to cause the shaft  302  to rotate. 
     In various embodiments, each blade  202  may be configured to rotate at the same speed and duration such that the cutting device  100  creates a plurality of cuts each having the same length, depth, and width. By way of example, the cutting device  100  shown throughout the figures includes four blade sets  104  each having two blades  202 . In this example embodiments, the cutting device  100  can create 8 cuts (2 per blade set  104 ) into a roadway. Two cuts from a first blade set  104  can be spaced a predetermined distance away from two cuts from a second blade set  104  of the four blade sets  104 . For example, the cutting device  100  can include sixteen spacers  106  positioned between the first blade set  104  and the second blade set  104  such that the cuts of each blade set  104  is positioned a distance of the width of sixteen spacers  106  apart from one another. In the same example, each blade  202  of each blade set  104  may also be spaced a second predetermined space apart from one another. For example, the cutting device  100  may include three spacers  106  positioned between each blade  202  of the blade sets  104  such that each cut made by the blades  202  in each blade set  104  are spaced a distance of the width of three spacers  106  apart from one another. 
       FIG.  10    depicts the roadway cutting device  100  coupled to a portion of machinery  1002 , such as construction machinery. As shown in  FIG.  10   , the roadway cutting device  100  can couple to one or more portions of the machinery  1002  (e.g., via structure  90  and machine attachment  94 ) such that the roadway cutting device  100  can operate with the machinery  1002 . For example, the machinery  1002  may include one or more wheels to facilitate moving the roadway cutting device  100  along a roadway (e.g., shown as roadway  1004 ) for the device  100  to create cuts into the roadway  1004 . 
       FIG.  11    depicts one example of a set  1104  of relief cuts  1102 . For example,  FIG.  11    depicts an example of two sets  1104  of relief cuts  1102  on a roadway  1004 . As shown in  FIG.  11   , the roadway cutting device  100  may be configured to cut a first set  1104  of relief cuts  1102  (e.g., shown as cut  1102   a  and  1102   b ). The roadway cutting device  100  may be configured to cut a second set  1104  of relief cuts  1102  (e.g., shown as cut  1102   c  and cut  1102   d ) at a predetermined distance from the first set  1104 . As shown in  FIG.  11   , each set  1104  of relief cuts  1102  may correspond to a respective blade set  104  and each relief cut  1102  may correspond to a respective blade  202 , such that each set  1104  of cuts  1102  is spaced a predetermined distant apart from one another (e.g., corresponding to a distance between blade sets  104 ). Similarly, each cut  1102  may be spaced a predetermined distance apart from one another (e.g., corresponding to a distance between each blade  202  of one blade set  104 ). 
       FIG.  12    depicts an illustration of a method  1200  of manufacturing a cutting device  100 , according to an exemplary embodiment.

For example, the first blade  202  can slide along the shaft  302  such that the first blade  202  engages with a portion of the first connector base  502 . 
     The method  1200  can include sliding, along the shaft  302 , a first connector cap  504  from the second end  404  toward the first end  402 , as depicted in step  1210 . For example, the first connector cap  504  can slide along the shaft  302  such that the first connector cap  504  engages with a portion of the first blade  202 . 
     The method  1200  can include sliding, along the shaft  302 , a second subset of spacers  106  from the second end  404  toward the first end  402 , as depicted in step  1212 . For example, the second subset of spacers  106  can slide along the shaft  302  such that a spacer  106  of the second subset of spacers  106  engages with a portion of the first connector cap  504 . 
     The method  1200  can include sliding, along the shaft  302 , a second connector base  502  along the shaft  302  from the second free end  404  toward the first end  402 , as depicted in step  1214 . For example, the second connector base  502  can slide along the shaft  302  such that the second connector base  502  engages with a spacer  106  of the second subset of spacers  106 . 
     The method  1200  can include sliding, along the shaft  302 , a second blade  202  from the second end  404  toward the first end  402 , as depicted in step  1216 . For example, the second blade  202  can slide along the shaft  302  such that the second blade  202  engages with a portion of the second connector base  502 . 
     A portion of the method  1200  is illustrated throughout  FIGS.  7 - 9   . For example,  FIG.  7    illustrates a subset of spacers (shown as subset  702 ) sliding along the shaft  302  from the second end  404  toward the first end  402  (not shown in  FIG.  7   ). The subset  702  can slide along the shaft  302  such that at least one spacer abuts a portion of the connector cap  504 , as shown in  FIG.  7   . 
       FIG.  8    illustrates a connector base  502  slid along the shaft  302  from the second end  404  toward the first end  402  (not shown in  FIG.  8   ). The connector base  502  can engage with a portion of the subset  702  of spacers, as shown in  FIG.  8   .  FIG.  9    illustrates a blade  202  slid along the shaft  302  to engage with a portion of the connector cap  504 .  FIG.  9    also shows a connector cap  504  slid along the shaft  302  to engage with a portion of the connector base  502  (not shown) and another subset of spacers  902  disposed between a first connector base (not shown in  FIG.  9   ) and a second connector base (shown as the connect base  502  positioned closest to the second end  404 ).
