Abstract
A finishing apparatus modifies the physical structure along the edge of a metal knife blade wherein the edge is formed at the junction of two edge facets presharpened with abrasives. The finishing apparatus consists of at least one precision angular knife guide that positions the edge of the blade into contact with the rigid surface of a driven moving member and positions the plane of the adjacent edge facet at a precise predetermined angle relative to the plane of the rigid surface that is harder than the metal of the knife and is without tendency to abrade.
