Beschreibung
Zusammenfassung:	A razor blade including: a substrate having a tip portion including a tip region, a blade body including a base, and first and second outer sides disposed opposite a split line of the substrate that converge at a tip; and first and second coatings disposed substantially on the first and second outer sides, respectively. Also provided is a method of coating the razor blade, including: applying a first coating to at least a portion of the first outer side; and applying a second coating to at least a portion of the second outer side. The first and second coatings each extend from the tip region toward the base and are substantially different, as compared to each other. One or both of the first and second coatings comprise a plurality of layers of material.
