Abstract
The razor blade comprises a substrate on which is formed a wedge shaped sharpened edge. The wedge has an an included angle of less than thirty degrees and a tip radius of less than 1200 angstroms. An interlayer of material, chosen from the group of molybdenum, nickel, niobium, silicon, silicon carbide, tantalum, vanadium and their alloys, is deposited on the wedge in a thickness less than 500 angstroms. A layer of diamond or diamond like carbon is deposited on the interlayer. This final layer has a thickness of at least 1200 angstroms on the wedge flanks to a tip radius of 40 microns.
