Abstract

At least the surface region of at least the cutting edge of a razor blade comprises an oxide of chromium. The blade may be of tough tool steel and the coating may be applied by electrodeposition, electrophoretic deposition, flame-spraying or resin-bonding and may subsequently be spark-hardened.ALSO:At least the surface region of at least the cutting edge of a razor blade comprises an oxide of chromium.
