ABSTRACT:
A scalloped cutting edge is formed on a knife blank by disposing the blank between corresponding faces of a punch and die assembly, whereby a resilient face of the punch compresses the blank into a plurality of scallop-shaped depressions formed in the face of the die, thereby imparting a corresponding scalloped configuration to the edge portion of the blank is then sharpened by partially removing the convex side of the scallops by beveling the blank edge portion.
