Abstract:
1. A finishing apparatus for modifying the physical structure along the edge of a metal knife with the edge being formed at the junction of two edge facets preshaped with abrasives, comprising at least one precision angular knife guide having a guide surface to dispose one of the facets at a vertical angle A which is the angle of said guide surface to the plane of the one facet resulting from the preshaping, a driven moving member having an outer peripheral edge and a rigid side surface having an exposed non-abrasive generally smooth texture, said rigid side surface having a constantly moving contact surface which is to be contacted by the knife edge at the one facet with the one facet being disposed toward said contact surface, said contact surface and said guide surface forming a vertical angle α which is precisely established by said guide surface and is to be close to the angle A, and said rigid side surface being made of a hard material to be harder than the metal of the knife and to be without tendency to abrade.
