ABSTRACT:
A safety razor blade has a blade body with a substantially planar upper surface. A row of blunt convex protrusions are spaced along the forward edge portion of the blade body in a comb-like configuration. The protrusions have upper surfaces substantially coplanar with the upper surface of the blade body. Cutting elements are provided between the protrusions, each cutting element having an upper surface which tapers downwardly from the upper surface of the blade body to a cutting edge. The protrusions extend beyond the respective cutting edges.
