ABSTRACT:
A fine smooth finish can be obtained on blades without grinding by drawing them against a rotating hardened disk with a smooth peripheral edge. One or a pair of hardened disks having smooth, rounded peripheral edges being disposed adjacent to and partially received by knife-guiding structure, having rotation imparting drive. The use of smooth edged hardened disks enables a very fine finished edge to be obtained, similar to the edge resulting from the use of a hand held steel, and often better.
