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.

Coatings for a razor blade

A razor blade including a substrate with a coating joined to the substrate defining a coated blade. The coated blade including a cutting edge being defined by a blade tip having a tip radius of from 50 to 350 angstroms. The coated blade having a pair of first facets extending from the blade tip and a pair of second facets extending from the respective first facets, a facet angle from 90&#xb0; to 135&#xb0;, a facet width from 0.38 micrometers to 0.65 micrometers a wedge angle from 5&#xb0; to 30&#xb0;, and a thickness of between 0.8 and 1.5 micrometers measured at a distance of 1 micrometer from the blade tip.

Razor blades having a wide facet angle

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.

Multi-layer coatings for a razor blade

A method of treating one or more coated razor blade edges comprising the steps of: (a) treating said one or more coated razor blade edges in a solvent, thereby modifying said one or more coated razor blade edges in said solvent; (b) treating said modified one or more coated razor blade edges in said modified solvent and further modifying said one or more modified coated razor blade edges and said modified solvent; and (c) repeating step (b) one or more times.
