ABSTRACT:
A razor blade includes a substrate with a wedge-shaped edge, an interlayer of material selected from the group consisting of silicon, silicon carbide, vanadium, tantalum, nickel, niobium, and niobium-molybdenum alloy and alloys of such materials on the tip and flanks of the wedge-shaped edge, the thickness of the interlayer preferably being in the range of about 50-500 angstroms, and a layer of diamond or diamond-like carbon material on the interlayer that preferably has a thickness of about two thousand angstroms and that defines a tip radius of less than about 1000 angstroms.
