Description:
[0001]    This application is related to pending patent application Ser. No. 11/226,811, entitled Nail Clipper, that was filed on Sep. 13, 2005. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The present invention, in general, relates to personal grooming devices and, more particularly, to toe and finger nail clippers. 
         [0004]    Nail clippers, the term herein including either toe or finger nail type of clippers, are generally well known. 
         [0005]    Nail clippers have certain problems. For example, prior art designs tend to spray the clippings into a room. The clippings may be sharp and can even spread infection. Therefore, it is desirable to contain clippings. 
         [0006]    However, prior art nail clippers include a center post that engages with a pivoting lever. The pivoting lever, pressing upon a ridge in the center post applies pressure to the clipper sufficient to urge a pair of opposite sides, and therefore also the blades, toward one-another during use. 
         [0007]    The center post, though necessary, provides an obstruction that certain of the clippings inevitably must impact. The clippings bounce off of the center post and are scattered. Any prior art type of modification intended to retain the clippings has proven to be ineffective when they are bouncing off of the center post. 
         [0008]    Other prior-art types of nail clippers do not fold sufficiently flat for storage. Others do not apply leverage that can create sufficient force to cut through difficult nails without requiring a great deal of force by the user. 
         [0009]    Additionally, prior art nail clippers include considerable metal that has been machined. This is considerably more expensive than plastic, for example. However, all prior art designs have heretofore included a fully functional metallic nail clipper, with perhaps plastic surround components as well. This has been expensive. 
         [0010]    There is a need to an inexpensive nail clipper. There is a need for a disposable nail clipper that is also inexpensive. Such a device could be given away at finer hotels or sold for minimum cost. It could also be a free item that included advertising, for example. 
         [0011]    Nail clippers are expensive because of the machining that is required to manufacture the metal portions thereof. The top and bottom blades must not only be cut to a fine edge, but they must align precisely. It is relatively inexpensive to make a blade, but the manufacture of two blades that mesh precisely together, is what drives up the cost of manufacture. 
         [0012]    Also, because nail clippers include so much metal, they are detected at airport security checks and often result in the searching of personal sundries that would not otherwise be so scrutinized. They may even be confiscated as a potentially dangerous weapon, which of course is a debatable assessment, but if confiscated it leaves the person without a nail clipper when they reach their destination. It is desirable to include so little metal with a nail clipper that it does not register as a potential threat during airport check-in procedures. 
         [0013]    Accordingly, there exists today a need for a nail clipper with blade-insert that helps ameliorate the above-mentioned and other difficulties. 
         [0014]    Clearly, such an apparatus would be a useful and desirable device. 
         [0015]    2. Description of Prior Art 
         [0016]    Nail clippers are, in general, known. While the structural arrangements of the above described known types of devices may, at first appearance, have similarities with the present invention, they differ in material respects. These differences, which will be described in more detail hereinafter, are essential for the effective use of the invention and which admit of the advantages that are not available with the prior devices.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0037]    Referring to all of the drawing figures and now primarily to  FIG. 1  is shown, a first disposable type of a nail clipper with blade-insert, identified in general by the reference numeral  10 . 
         [0038]    A one-piece plastic frame member  12  is molded out of a sufficient grade of plastic, nylon, or other material other than a metal. 
         [0039]    A spring  14  is provided to push an upper half  12   a  of the frame member  12  away from a bottom half  12   b . The spring  14  fits into a hole  16  provided in the bottom half  12   b  and a similar hole (not shown) that is provided in the top half  12   a.    
         [0040]    If desired, a greater amount of plastic material  18  (shown in dashed lines) is provided near a rear  20  of the frame member  12 . The plastic material  18  is used instead of the spring  14  to urge the bottom half  12   b  away from the upper half  12   a  when no force is applied to any portion of the frame member  12 . 
         [0041]    If desired, other types of springs (not shown) can be used. 
         [0042]    The upper half  12   a  of the frame member  12  of the first disposable type of a nail clipper with blade-insert  10  includes a first enlarged front portion, identified in general by the reference numeral  22 . 
         [0043]    The first enlarged front portion  22  includes a vertical section  24  that is generally perpendicular to a longitudinal axis of the upper half  12   a . An inside radius  26  connects the vertical section  24  with the upper half  12   a  along an inside surface of the first disposable type of a nail clipper with blade-insert  10 . An outside radius  28  similarly connects the vertical section  24  with the upper half  12   a  along an outside surface of the first disposable type of a nail clipper with blade-insert  10 . 
         [0044]    A first recess  30  is provided in a bottom surface  32  of the vertical section  24  that extends across the width thereof. The first recess  30  can be straight or it may include a curve, as desired. 
         [0045]    A blade  34  is inserted into the first recess  30  and is held in place by friction or by any preferred method or combination of methods, as desired. For example, holes (not shown) can be provided through the blade  34 . Plastic material from the vertical section  24  can extend through the holes sufficient to secure the blade  34  precisely in position. If desired, an adhesive  35  may be used. 
         [0046]    The blade  34  includes a small piece of planar material with a cutting edge  36  that is disposed closest toward the bottom half  12   b . The blade  34  is preferably formed of metal, although other materials, for example a ceramic material, can be used, if desired. The blade  34  preferably includes a curvature  38  along the cutting edge  36  as is common with prior art types of nail clippers (not shown). 
         [0047]    The blade  34  small piece of planar material is sharpened and bent (if desired) prior to insertion into the first recess  30 . As such, the cost of manufacture of the blade  34  is minimal. 
         [0048]    The bottom half  12   b  includes a second enlarged front portion, identified in general by the reference numeral  40 . The second enlarged front portion  40  is a mirror in construction and composition to the first enlarged front  22 . 
         [0049]    A second blade  34   a  of the second enlarged front  40  is identical to the blade  34 , just oriented upside down with respect thereto. 
         [0050]    A second cutting edge  36   a  of the second blade  34   a  aligns with the cutting edge  36  when the upper half  12   a  and the bottom half  12   b  of the frame member  12  are urged together. 
         [0051]    The upper half  12   a  and the lower half  12   b  are urged toward each other when a force sufficient to overcome hysteresis and the force of the spring  14  is applied to the upper half  12   a  in the direction and location of arrow  42  and to the bottom half  12   b  in the direction and location of opposite arrow  44 . 
         [0052]    When urged together, the cutting edge  36  and the second cutting edge  36   a  align perfectly with respect to each other. 
         [0053]    A finger nail (not shown) or a toe nail (not shown) is inserted between the blade  34  and the second blade  34   a  and is severed by the cutting edge  36  and by the second cutting edge  36   a  when sufficient force is applied to urge the upper half  12   a  and to the bottom half  12   b  toward each other. 
         [0054]    Typically, a thumb and finger of a user can supply sufficient force to sever the nail. If desire, the first disposable type of a nail clipper with blade-insert  10  is modified to include a lever  52  (see  FIG. 2 ) to apply greater force to urge the cutting edge  36  and the second cutting edge  36   a  together. 
         [0055]    If desired, an advertisement  46  is provided wherever preferred on the frame member  12 . 
         [0056]    Because the cost of manufacture is so little for the first disposable type of a nail clipper with blade-insert  10 , they can be sold at very low cost, used for a period of time until the cutting edge  36  and the second cutting edge  36   a  become dull, and then disposed of. 
         [0057]    If the spring  14  is eliminated, other than the blade  34  and the second blade  34   a  there is no metal. Of course, the spring  14  could be changed from a coil-type of the spring  14  to include a leaf-type of the spring  14  that is disposed further toward the rear of the nail clipper with blade-insert  10  (not shown) than is the spring  14 , as shown. This makes the first disposable type of a nail clipper with blade-insert  10  lightweight and very inexpensive to manufacture. 
         [0058]    Unlike all known prior art types of nail clippers, the blade  34  and the second blade  34   a  are separate parts. They are not formed of a continuous piece of metal (as is the prior art). Because the blade  34  and the second blade  34   a  are not continuous, precision machining of the each prior art cutting edge with respect to the other is eliminated. 
         [0059]    This greatly reduces the cost of manufacture because the blade  24  and the second blade  34   a , being separate components, are easy to manufacture and to machine the cutting edge  36  and the second cutting edge  36   a.    
         [0060]    Luxury hotels can provide the first disposable type of a nail clipper with blade-insert  10  for free or at low cost. Manufacturers of any type of a product who wish to increase customer awareness of their products (or services) can include their name, telephone number, and website as part of the advertisement  46 . The manufacturers may wish to give the first disposable type of a nail clipper with blade-insert  10  away for free. 
         [0061]    Every time a person who has received one for free cuts his or her finger nails or toe nails, they are apt to be reminded of the manufacturer and to think favorably of the manufacturer. If repeated enough times, when a purchase decision is required by the person for a product offered by the manufacturer, it is likely that the name of the manufacturer will spring favorably to mind. 
         [0062]    The frame member  12  can be any desired color of plastic. For example, a pink color of the frame member  12  may appeal to girls and women whereas another color may be more likely to appeal to boys and men. 
         [0063]    Furthermore, because there is so little metal, airport security devices are not likely to detect the first disposable type of a nail clipper with blade-insert  10  during security screening. This prevents delays and possible confiscation of the first disposable type of a nail clipper with blade-insert  10  by overly zealous security personnel. 
         [0064]    Referring now primarily to  FIG. 2  is shown, a second disposable type of a nail clipper with blade-insert, identified in general by the reference numeral  50 . 
         [0065]    A plastic lever  52  is pivotally attached to a top of a vertical plastic pin  54  by a horizontal pin  55 . The pin  54  passes through a pin hole  56  provided in a first modified frame member  58 . 
         [0066]    The pin  54  continues to pass through a second pin hole  60  provided in a second modified frame member  62 . The first modified frame member  58  and the second modified frame member  62  are identical, just inverted with respect to each other. They are each formed of plastic or nylon preferably and include a center wedge  64  at an end opposite to where the pin  54  is disposed. 
         [0067]    The pin  54  includes a split bottom  54   a . The two opposite sides of the split bottom  54   a  are urged together sufficient to pass through second pin hole  60 . A pin wedge  65  is urged into the split bottom  54   a  sufficient to spread the two opposite sides of the split bottom  54   a  apart an amount sufficient to prevent the split bottom  54   a  from passing back up and through the second pin hole  60 . 
         [0068]    The first modified frame member  58  and the second modified frame member  62  are preferably planar members that approximate the size of current prior art types of nail clippers. Prior art types of nail clippers come in a variety of sizes and it is to be understood that the instant invention can similarly be provided in a variety of sizes. 
         [0069]    The wedge  64  is either welded (by ultrasound or other means) or adhered (by an adhesive) to the first modified frame member  58  and to the second modified frame member  62 . Injection molding or other known or future manufacturing techniques can, of course, be used to form any version of the nail clipper with blade-insert  10 ,  50  ( 100 ,  150 ,  200 , as described hereinafter). 
         [0070]    The wedge  64  orients the first modified frame member  58  and the second modified frame member  62  in a spaced apart relationship where they are disposed further apart at a front, identified in general by the reference numeral  66  than at an opposite rear  68 . If desired, the wedge  64  is molded as an integral part of the second disposable type of a nail clipper with blade-insert  50  so that the wedge  64 , the first modified frame member  58 , and the second modified frame member  62  are one continuous piece. 
         [0071]    A first modified blade  70  includes a blade hole  72  through which the pin  54  passes. The first modified blade  70  includes the cutting edge  36  which is substantially identical to that of the first disposable type of a nail clipper with blade-insert  10 . The first modified blade  70  is attached at the front  66  of the first modified frame member  58  by adhesive or any preferred means. 
         [0072]    A second modified blade  74  is identical to the first modified blade  70  and is similarly attached in an inverted fashion to the second modified frame member  62  so that the cutting edge  36  and the second cutting edge  36   a  of the second modified blade  74  are aligned with respect to each other and face each other, as they did on the first disposable type of a nail clipper with blade-insert  10 . 
         [0073]    When the lever  52  is depressed in the direction of arrow  76 , a fulcrum  78  of the lever  54  applies a mechanical advantage to the top of the first modified frame member  58  sufficient to urge it toward the second modified frame member  62 . 
         [0074]    The pin  54  prevents the second modified frame member  62  from moving away from first modified frame member  58  as the lever  52  is depressed. This causes the second modified blade  74  and the first modified blade  70  to move toward each other until the cutting edge  36  and the second cutting edge  36   a  align with each other and any finger nail or toe nail placed there-between has been severed. 
         [0075]    The second disposable type of a nail clipper with blade-insert  50  shares the advantages of being lightweight, inexpensive to manufacture, low cost of purchase, space for the advertisement  46 , and because of little metal, freedom from detection by airport security devices of the first disposable type of a nail clipper with blade-insert  10 . 
         [0076]    If desired, a retainer clip  79  can be inserted over the opposite rear  68  of the first modified frame member  58 , the wedge  64 , and the second modified frame member  62  to secure them together. The retainer clip  79  if formed of metal or any preferred material and can be crimped in place to provide a low-cost manufacturing method. 
         [0077]    Referring now primarily to  FIG. 3  is shown a portion of a first half of a third disposable type of a nail clipper with blade-insert, identified in general by the reference numeral  100 . 
         [0078]    A front portion  102   a  of a second modified frame member  102  is shown. The second modified frame member  102  and those portions of the third disposable type of a nail clipper with blade-insert  100  not shown or otherwise described as being different than the previously described embodiments, are substantially the same as with either the first disposable type of a nail clipper with blade-insert  10  or, alternately, the second disposable type of a nail clipper with blade-insert  50 . 
         [0079]    The front portion  102   a  includes a horizontal recess  104  into which a third modified blade  106  is disposed and attached in any preferred manner. For all embodiments described hereinafter, the cutting edge  36  is similarly included. Also, for all embodiments described hereinafter, a bottom half that is not shown includes a mirror image of the top portion which is shown and described. The cutting edge  36  will similarly align with the second cutting edge  36   a  (of the bottom half) when the bottom half is urged toward the top half (i.e., for example, toward the second modified frame member  102 ) that is shown. 
         [0080]    The third disposable type of a nail clipper with blade-insert  100  provides the advantages of the previously described embodiments. 
         [0081]    Referring now primarily to  FIG. 4  is shown a portion of a first half of a first replaceable blade type of a nail clipper with blade-insert, identified in general by the reference numeral  150 . 
         [0082]    A replacement blade assembly, identified in general by the reference numeral  152  is shown in a spaced-apart orientation, ready for insertion into an open end  154  of a third modified frame member  156 . 
         [0083]    The replacement blade assembly  152  is similar to the front portion  102   a  of the third disposable type of a nail clipper with blade-insert  100 . However, the replacement blade assembly  152  is detachably-attachable with respect to the third modified frame member  156 . 
         [0084]    A pair of tangs  158 ,  160  extend from the replacement blade assembly  152  and each include a respective beveled leading edge  162 ,  164 . Each leading edge  162 ,  164  will extend progressively further away from a center of the replacement blade assembly as it passes toward the third modified blade  106  until it terminates at a retaining edge  166 ,  168  that are each perpendicular with respect to arrow  170 . 
         [0085]    The replacement blade assemblies  152  are expected to be sold in pairs for replacement of a prior set when the cutting edges  36 ,  36   a  of the first replaceable blade type of a nail clipper with blade-insert  152  become dull. 
         [0086]    To remove a previously used and now dull replacement blade assembly  152  from the third modified frame member  156  (or bottom member; not shown), a force is simultaneously applied through a pair of side openings  172 ,  174  that are provided in the third modified frame member  156  to the two leading edges  162 ,  164 . 
         [0087]    The two leading edges are urged toward each other an amount sufficient to permit the retaining edges  166 ,  168  to clear the side openings  172 ,  174 . The pair of tangs  158 ,  160  bend inward in response to the force that is applied. 
         [0088]    A force in the opposite direction of arrow  170  is also simultaneously applied to the replacement blade assembly  152  while the leading edges  162 ,  164  are depressed. When the retaining edges  166 ,  168  clear the side openings  172 ,  174 , the replacement blade assembly  152  is pulled out of the open end  154  of the third modified frame member  156 . 
         [0089]    This is repeated for both the first (top) half of the first replaceable blade type of a nail clipper with blade-insert  150  and also for the second (bottom) half (not shown). 
         [0090]    To insert a new replacement blade assembly  152  after an older one has been removed, it is simply oriented as shown in the drawing and urged in the direction of arrow  170  until a click is heard as the retaining edges  166 ,  168  pass beyond the front edge of each of the side openings  172 ,  174 . The replacement blade assembly  152  is accordingly held in position. Furthermore, the cutting edge  36  of the top replacement blade assembly  152  is aligned with the second cutting edge  36   a  (not shown) of the bottom replacement blade assembly  152 . 
         [0091]    An additional benefit is provided over the previous embodiments described herein. The additional benefit is that the first replaceable blade type of a nail clipper with blade-insert  150  can be restored to like-new cutting ability by periodically replacing the replacement blade assemblies  152 . The replacement blade assemblies  152  are a consumable item, similar to razor blades, which can prove to be as profitable or potentially even more profitable than the sale of the first replaceable blade type of a nail clipper with blade-insert  150 . 
         [0092]    Referring now primarily to  FIG. 5  and also to  FIG. 6  is shown a portion of a first half of a second replaceable blade type of a nail clipper with blade-insert, identified in general by the reference numeral  200 . 
         [0093]    A second replacement blade assembly  202  includes a modified blade  204  that is attached to a channel member  206 . The modified blade  204  and the channel member  206  are preferably formed of steel. The channel member  206  in cross-section ( FIG. 6 ) includes a generally rectangular “C-shape” that is adapted to slide over an end  208  of a fourth modified frame member  210 . 
         [0094]    The second replacement blade assembly  202  includes an alignment hole  212 . The fourth modified frame member  210  includes an alignment protrusion  214  that engages with the alignment hole  212  when the second replacement blade assembly  202  is fully inserted onto an end of the fourth modified frame member  210 . 
         [0095]    The alignment protrusion  214  disposed in the alignment hole  212  provides two benefits. Together, they ensure that the second replacement blade assembly  202  is fully and properly inserted on the fourth modified frame member  210  and they help retain the second replacement blade assembly  202  in position. 
         [0096]    To ensure that the second replacement blade assembly  202  is not inserted too far onto the fourth modified frame member  210 , an elevated ridge  216  is preferably included as part of the fourth modified frame member  210  that prevents over-insertion of the second replacement blade assembly  202 . 
         [0097]    To remove the second replacement blade assembly  202  from the fourth modified frame member  210  it is grasped and sufficient force is applied in the direction of arrow  218  while retaining the remainder of the second replaceable blade type of a nail clipper with blade-insert, identified in general by the reference numeral  200 . The resistance provided by the alignment protrusion  214  in the alignment hole  212  is overcome and the second replacement blade assembly is separated apart from the fourth modified frame member  210 . 
         [0098]    To add a new second replacement blade assembly  202  it is urged in a direction opposite that of arrow  218  until the alignment protrusion  214  is in the alignment hole  212  and a rear edge of the second replacement blade assembly  202  is disposed against the elevated ridge  216 . 
         [0099]    Of course, when replacement is warranted, two of the second replacement blade assemblies  202  are used at both the top and bottom halves of the second replaceable blade type of a nail clipper with blade-insert  200 . 
         [0100]    If desired, the instant invention can, of course, be modified for use with the disclosure of the related patent application that was identified in the first sentence of the specification in such a way as to eliminate the prior art type of clipper that was used and to replace it with one of the embodiments, as described herein. Accordingly, pending patent application Ser. No. 11/226,811, entitled Nail Clipper, that was filed on Sep. 13, 2005, is incorporated herein by reference. 
         [0101]    For example, referring now primarily to  FIG. 7  is shown, a fourth disposable type of a nail clipper with blade-insert, identified in general by the reference numeral  250 . 
         [0102]    The fourth disposable type of a nail clipper with blade-insert  250  is similar to the first disposable type of a nail clipper with blade-insert  10 . However, the fourth disposable type of a nail clipper with blade-insert  250  includes a raised pivot area  252  in a bottom half  254  of a further modified frame member  256 . The further modified frame member  256  is preferably formed of plastic or nylon (not metal). 
         [0103]    The raised pivot area  252  extends across the width of the bottom half  254 . A modified lever  258  is preferably formed of a plastic or nylon and pivots about a bottom pivot pin  260 . The bottom pivot pin  260  passes through the raised pivot area  252  and also through a bottom end of a pair of opposite lower sides  262  of the modified lever  258 . The modified lever  258  is similar in design to that which was disclosed in the above-referenced pending patent application. 
         [0104]    If desired, the bottom pivot pin  260  can eliminated and a pair of modified bottom pivot pins (not shown) can instead be provided. The modified bottom pivot pins are each molded as a cylindrical extension to each of the pair of opposite lower sides  262  proximate the bottom thereof and extending inward a predetermined distance toward each other. A corresponding cylindrical opening is provided on each side of the raised pivot area  252  to receive one of the pair of modified bottom pivot pins. 
         [0105]    This can help to lower manufacturing and assembly cost. To assemble the fourth disposable type of a nail clipper with blade-insert  250  when the pair of modified bottom pivot pins are used, the pair of opposite lower sides  262  are urged apart an amount sufficient to permit each of the modified bottom pivot pins to enter into the corresponding cylindrical openings in the raised pivot area  252 , where they are urged inward by their own elastomeric properties. The modified bottom pivot pins then snap into the cylindrical openings where they are retained. 
         [0106]    The pair of opposite lower sides  262  (the rear side is not visible) are disposed on opposite sides of the further modified frame member  256 . The modified lever  258  includes an opening (as indicated by bracket  263 ) that extends from the bottom pivot pin  260  (i.e., the bottom of the modified lever  258 ) up to an upper cross member  264 . The opening extends along the length of the opposite lower sides  262  as shown by bracket  263 . 
         [0107]    The upper cross member  264  extends across the width of the modified lever  258  and when the modified lever  258  is urged in the direction shown by arrow  266 , the modified lever  258  bears against and urges an upper half  268  of the further modified frame member  256  toward the bottom half  254 . The cutting blade  34  and the second cutting blade  34   a  are then drawn together sufficient to sever a toe nail or a finger nail. 
         [0108]    The upper cross member  264  can extend up to and into a finger pad  270  or, if preferred, it can extend only partially along the remaining length of the modified lever  258 . For storage, the modified lever  258  is pivoted about the bottom pivot pin  260  in the direction of arrow  272  until it is disposed under the bottom half  254  and is adjacent thereto. 
         [0109]    The only metal used in the fourth disposable type of a nail clipper with blade-insert  250  are for the cutting blade  34  and the second cutting blade  34   a  and the bottom pivot pin  260 . Of course, the bottom pivot pin  260  could be made of a material other than metal, if preferred. Also, if the modified bottom pivot pins are used instead of the bottom pivot pin  260 , they would not be formed of metal. 
         [0110]    Accordingly, the fourth disposable type of a nail clipper with blade-insert  250  includes all of the advantages of the first disposable type of a nail clipper with blade-insert  10  plus the added ease of use that is provided by the mechanical advantage created by the modified lever  258 . 
         [0111]    As disclosed, the fourth disposable type of a nail clipper with blade-insert  250  is expected to be used for a period of time and then disposed of. Depending on the quality of construction, the period of time can be less than, equal to, or even longer than that of the known prior-art types of nail clippers. 
         [0112]    However, if preferred, it can be further modified so that it includes either the replacement blade assembly  152  or the second replacement blade assembly  202 , or any other possible type of modified replacement blade assembly (not shown). 
         [0113]    After having had benefit of the instant disclosure, it is anticipated that other and further modifications will be obvious to those possessing ordinary skill. 
         [0114]    For example, the first enlarged front portion  22  of the first disposable type of a nail clipper with blade-insert  10 , the second disposable type of a nail clipper with blade-insert  50 , the third disposable type of a nail clipper with blade-insert  100 , or the fourth disposable type of a nail clipper with blade-insert  250  could each be modified, as desired, so as not to be disposable but to include a preferred type of replacement blade assembly  152 ,  202  (or newly designed). 
         [0115]    For example, any of the disposable types of a nail clipper with blade-insert  10 ,  50 ,  100 ,  250  can be modified to include the teachings of the first replaceable blade type of a nail clipper with blade-insert  150  ( FIG. 4 ) including a modified replacement blade assembly (not shown). 
         [0116]    The modified replacement blade assembly would be similar to the replacement blade assembly  152  except that the cutting blade  34  and the second cutting blade  34   a  of the modified replacement blade assembly would be attached vertically (as shown in  FIG. 1  or  FIG. 7 ) instead of horizontally, as shown in  FIG. 4 . This is to illustrate only a small sampling of the many modifications that are now possible regarding the replacement blade assemblies  152 ,  202 . 
         [0117]    Similarly, any disposable type of a nail clipper with blade-insert  10 ,  50 ,  100 ,  250  can be modified to include the second replaceable blade type of a nail clipper with blade-insert  200 . 
         [0118]    Also, any of the versions herein can include any type of an enclosure (not shown) to retain the nail clippings. 
         [0119]    An additional modification could allow replacement of only the cutting blade  34  instead of the replacement blade assembly  152  (or the second replacement blade assembly  202 ) which include additional components other than the cutting blade  34 . 
         [0120]    For example, the first recess  30  could be modified to secure the cutting blade  34  in position, allow its withdrawal, and permit the insertion of a replacement cutting blade  34  therein. 
         [0121]    As an example of a possible way to secure the cutting blade  34  in a modified type of a first recess (not shown), a modified type of a cutting blade (not shown) could include an opening into which a protrusion that is provided in the modified type of a first recess would engage, similar to way in which the alignment hole  212  and the alignment protrusion  214  cooperate. 
         [0122]    The modified type of a cutting blade is grasped and pulled out and another is urged into the modified type of a first recess. This is generally not preferred over use of the replacement blade assemblies  152 ,  202  because of the possibility of injury occurring during removal or insertion of the modified type of a cutting blade into the modified type of a first recess. 
         [0123]    Referring now to  FIG. 8 , for any version of the nail clipper with blade-insert  10 ,  50 ,  100 ,  150 ,  200 ,  250  the cutting blade  34  and the second cutting blade  34   a  require that the cutting edges  36 ,  36   a  contact each other when the device is urged into a closed position. The planar portion of each cutting blade  34 ,  34   a  does not have to be vertical or in parallel planar alignment with each other but could be disposed at an angle, if preferred. 
         [0124]    If desired, the cutting blades  34 ,  34   a  could be formed of a material other than metal, for example, a ceramic material. 
         [0125]    Other changes are also possible. As is well-known in the nail clipper arts, a radius is included in the cutting edges to provide a curvature to the nails (either toe or finger) when cut. Prior art designs machine the curvature into the cutting edges. However, with any version of the instant invention, the cutting blades  34 ,  34   a  can be formed of a flat material stock, if preferred, that is bent to provide the desired amount of curvature during assembly. This provides even lower cost for the manufacture of the cutting blades  34 ,  34   a.    
         [0126]    If preferred, any portion of any version of the instant invention as described herein that is formed of a plastic, nylon, or polymer, for example, can include either a solid core or a hollow core. Proper selection of materials and skilful design will, of course, allow minimal use of the plastic, nylon, or polymer. Not only does minimal use reduce manufacturing cost, it also reduces weight, which in turn, can substantially reduce shipping costs. This is especially true when compared with the known prior-art. Also, a lower weight makes portage of the instant invention easier to accomplish, whether it is placed in a pocket, purse, or added to a keychain, for example. 
         [0127]    The invention has been shown, described, and illustrated in substantial detail with reference to the presently preferred embodiment. It will be understood by those skilled in this art that other and further changes and modifications may be made without departing from the spirit and scope of the invention which is defined by the claims appended hereto.
