DETAILED DESCRIPTION

[0015] In the following detailed description of embodiments of the invention, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to one of ordinary skill in the art that the invention may be practiced without these specific details. In other instances, well-known features have not been described in detail to avoid unnecessarily complicating the description.

Objects and Advantages

[0016] The present invention discloses a compact portable sharpener for a curved jaw or nose short mouth nail clipper. The geometry of such clippers allows cutting edge preserving abrasion surface sharpeners sharpen a very limited number of times before the nail cutting edge wedge angle becomes too thick to sharpen.

[0017] An object of the invention is to provide a sharpening tool for short nosed curved clippers or cutters.

[0018] Another object of the invention is to provide a portable sharpener with holder.

[0019] Yet another object of the invention is to provide a sharpener which conforms even a slightly curved dull edge to a specific cutting edge cross-section.

[0020] FIG. 1 is an isometric diagram of a sharpener in according to an embodiment of the present invention.

[0021] A hand-held sharpener device showing V-body block 103 having two rectangular flat plate-shaped whetting surface assemblies 106 107 inclinedly installed on two opposing sidewalls of a V-body block 103 groove. The whetting groove transversely formed in a sharpener supporting V-body block. The two rectangular plate-shaped whetting surface assemblies 106 107 are protruding beyond the v-block body 103 and forming a cantilevered V-edge lip 105 establishing an extended sharpening surface beyond of the V-block body. Thus a curved short head nail cutter with a specific angle wedge cross-section cutting edge can be sharpened to its specific angle cutting edge sharpening with the same abrasion surface angle without being impeded by the sharpener block 103 and handle.

[0022] FIG. 2 is a front and side view of a sharpener in accordance with an embodiment of the invention.

[0023] The sharpener device is specifically for sharpening short nose curved cutters and clippers has slidable lip 201 rigidly coupled to a V-block 203. The V-block 203 has rectangular flat plate-shaped whetting surface assemblies 207 208 adjacent and rigidly coupled 209 to secure inward facing abrasive surfaces whetting groove. The wetting groove is formed in a sharpener surface supporting V-body block for back-and-forth sharpening of short nosed cutters. The two rectangular flat plate-shaped whetting surface assemblies 207 207 are inclinedly installed on two opposing sidewalls of a V-body block groove such that the whetting surface assemblies form specific preset and changeable angle V-shaped angles. The two rectangular plate-shaped whetting surface assemblies protruding beyond the v-block body and forming a cantilevered V-edge lip 205 providing an extended sharpening surface beyond of the V-block body 203.

[0024] FIG. 3 a cross-sectional view of a sharpener blade assembly in accordance with an embodiment of the invention. Clipper cross-sections are generally made for specific wedge angles. These may be for example x, y, and z. Therefore an aspect of the invention is to match the cutter cross-section angle with an equal sharpening angle, so as to sharpen only the cutter meat to the original angle, preserving the cutter for any future re-sharpening without changing the cutter angle.

[0025] A 1.sup.st flat plate-shaped whetting assembly having an rectangular frame 303 330 317 with a frame held insert-removable flat plate 305 332 319 having two flat sides, a side 1 fitting inside the frame 303 330 317 and flush with a V-block, and a side 2 having an abrasive or whetting surface facing a 2.sup.nd flat plat-shaped whetting surface 310 334 323 assembly. The 2.sup.nd flat plate-shaped whetting assembly having an installed rectangular frame 311 335 325 with an insert-removable held fitting wedge cross-section rectangular component 313 301 327 having two sides. The insert-removable 2.sup.nd frame held fitting wedge cross-section piece 313 301 327 angle having numerical values in compliance with a pre-set total V abrasion angle 307 329 315 specific to standard hand held sharpener cutting edges angles. A side 1 309 333 321 snuggly fitting and held inside the 2.sup.nd assembly frame 311 335 325 respectively and flush with the 2.sup.nd assembly adjacent V-block surface, and a side 2 310 334 323 having an abrasive or whetting surface facing the 1.sup.st rectangular flat plat-shaped assembly whetting surface 305 332 319 respectively. The pre-set total V abrasion wedge cross-section specific angles 307 327 315 are 30, 45, or 60 respectively.

[0026] FIG. 4 is an illustration of a sharpener with sharpener assembly and handles in accordance with embodiments of the invention.

[0027] In an embodiment V-block grip handle 401 is shown. In addition a shaver-like handle 413 is shown rigidly coupled to a V-block 405 via an insert attaching arm 409 to a V-block base side coupler 407 rigidly attached to a V-block 405 which is coupled to at least two whetting surface assemblies 403 facing each other and forming a V-shaped groove 411 with block overhanging lip for sharpening small nose cutters to their full cutter nose length without sharpener block impediment. Thus a sharpener can be held steady via a grip handle or a shaver-like handle which allow the user sufficient lateral clearance for a short nose cutter to be sharpened along its total cutting length.

[0028] FIG. 5 illustration of a sharpener with a ratably insertable handle in accordance with an embodiment of the invention

[0029] A handle 501 513 is rotably coupled 503 to an extended V-block 505 517 respectively with two V-block insert facing rectangular plate-shaped whetting surface assemblies 507 511 each protruding 519 as shown in the crossection, extending beyond the v-block body 517 and forming a cantilevered V-edge lip 519 establishing an extended sharpening surface beyond of the V-block body.

[0030] Therefore, while the invention has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this invention, will appreciate that other embodiments can be devised which do not depart from the scope of the invention as disclosed herein. Other aspects of the invention will be apparent from the following description and the appended claims.
