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).
