Abstract: A razor blade is provided comprising a substrate comprising a first portion and a second portion. The first portion may comprise first and second generally parallel outer surfaces. The second portion may comprise first and second sections separated by a split line. The first section may comprise a first facet extending directly from the first outer surface of the first portion and an end facet extending directly from the first facet. The second section may comprise an end facet. The end facets of the first and second sections may converge at a tip to define a cutting edge. The split line may pass through the tip and is generally parallel with and extends between the first and second outer surfaces of the first portion.

Abstract: 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.

Abstract: A method of optimizing a manufacturing process or a blade array of a razor cartridge using spatial information for a tip portion of a razor blade comprises the steps of: measuring, using an atomic force microscope including a probe having a high aspect ratio of a length to a half side angle and a probe tip with a radius less than a radius of an ultimate tip of the tip portion of the razor blade, the spatial information by traversing the probe across the tip portion of the razor blade; analyzing, by one or more processors, the spatial information as measured by the atomic force microscope, to determine one or more blade characteristics; and using the blade characteristics to adjust the manufacturing process to improve a design of the razor blade or to adjust a design characteristic of the blade array to improve a design of the razor cartridge.

One or both of the first and second coatings comprise a plurality of layers of material.

Abstract: A method of assembling a razor cartridge. A housing is injection molded. An elastomer is co-injection molded to the housing forming a pair of laterally spaced apart blade stabilizers. A primary blade member having a cutting edge is mounted to the housing. The cutting edge of the primary blade member is contacted with the laterally spaced apart blade stabilizers. A blade retention member is mounted to a top surface of the housing. A pair of lateral ends of the cutting edge of the primary blade member is constrained between the blade retention member and the pair of laterally spaced apart blade stabilizers.
