ABSTRACT:
An integrally backed single-edge razor blade has a plurality of projections struck from a margin of the blade remote from its cutting edge. The struck portions reinforce the blade and afford a blade edge remote from the cutting edge having a thickness greater than the thickness of the material forming the body of the blade. The blade may be formed by passing stock blade material through opposed dies for forming the projections as well as the conventional perforations through the blade.
