FIELD: personal usage items.
SUBSTANCE: invention relates to razor blades. Razor blade has a substrate containing a cutting edge with a profiled shape. Cutting edge is coated with a hardening coating deposited on the razor blade substrate, at least on the cutting edge area of the blade. Reinforcing coating covering the end of the substrate has a profiled shape and a convergent shape with two sides of the coating converging toward the end of the coating. Reinforcing coating contains a reinforcing nanocrystalline layer. Reinforcing nanocrystalline layer has at least one of areas enriched with titanium and boron-enriched regions.
EFFECT: improved hardness of the cutting edge and improved quality of shaving.
