Abstract
A method of manufacturing a straight knife includes pressing one end of a rounded austenitic stainless steel rod flat and press-cutting away an excess portion of the flattened end to form a blade; grinding the blade to form a slanted surface and an edge along at least a portion of the periphery of the blade; removing burrs along the slanted surface and the edge of the blade by electrolytic polishing or chemical polishing; and continuing with the electrolytic polishing or chemical polishing to form, at a tip of the slanted surface, a cutting portion of the blade having a cross-sectional shape defined by convex curves.
