Abstract
A plate device (22) and method for manually sharpening clipper blades (12). The plate (22) has an upper, rough sharpening surface (20) to which an abrasive sharpening compound (28) is applied. The compound (28) is applied as a thin film (32) covering substantially the full rough sharpening surface (20). A plurality of annular, concentric troughs or recesses (34) are formed in the surface (20). Compound (28) in excess of that necessary to form the thin film (32) can seep into these recesses (34). The rough sharpening surface (20) is domed to form a convex processing surface (20).
Claims4
A method of manually sharpening a blade of a clipper implement intended to be used in the grooming of horses, wherein said blade includes a plurality of teeth, each tooth normally having a concave surface to be brought into engagement with a sharpening surface for sharpening, comprising the steps of:
- (a) providing a sharpening member having a first convexly arcuate face defining a sharpening surface and a second convexly arcuate face defining a polishing surface, said first and second convexly arcuate faces facing in opposite directions;
- (b) applying a thin film of sharpening compound over the entire sharpening surface of the sharpening member;
- (c) diluting the sharpening compound applied to the sharpening surface by adding a small amount of water in order to facilitate the creation of a thin film of sharpening compound on the sharpening surface;
- (d) lightly rubbing the clipper blade surface over the sharpening surface of the sharpening member in a series of successive figure-8 passes;
- (e) inverting the sharpening member;
- and
- (f) lightly rubbing the clipper blade surface over the polishing surface of the sharpening member in a series of successive figure-8 passes.
Apparatus for manually sharpening a blade of a clipper implement to be employed for grooming horses, wherein said blade includes a plurality of teeth, each tooth being normally provided with a concave surface intended to be brought into engagement with a sharpening surface for sharpening, comprising:
- (a) a disk-like plate sharpening member including:
- (i) a first face having a plurality of concentric annular troughs formed therein, said first face defining a rough sharpening surface;
- and
- (ii) a second face, facing in a direction opposite a direction in which said first face faces, said second face defining a polishing surface;
- (b) wherein both said first face and said second face are convexly arcuate to a degree wherein the measure of convex arcuity is the same as the measure of concavity intended to be imparted to the teeth of said clipper blade.
