A razor cartridge having a first blade proximal to a front of the cartridge and having one or more first coatings disposed thereon, a second blade proximal to a back of the cartridge, the second blade having one or more second coatings disposed thereon, wherein a thickness of at least one of the one or more first coatings disposed on the first blade is less than a thickness of at least one of the one or more second coatings disposed on the second blade.

Razors and razor cartridges

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 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 modifying razor blade edges prior to a first use, the method comprising providing at least one razor blade having a coated razor blade edge, and mechanically modifying at least one coating of said coated razor blade edge. Also provided is an apparatus for modifying one or more coated razor blade edges, the apparatus comprising a support member for holding a plurality of razor blades with said coated razor blade edges, and an applicator for contacting a mechanical modifying material with at least a section of said coated razor blade edges.

Method for modifying coated razor blade edges

A method of manufacturing a razor blade by providing a razor blank strip having an edge. The razor blank strip is hardened to a hardness greater than 600HV. A pre-bending zone that is spaced apart from an edge of the razor blank is melted with a laser beam. The pre-bending zone is cooled after melting to form a re-solidification portion. The razor blank strip is segmented into individual blades. The individual blades are bent in the pre-bending zone.

Method of manufacturing bent razor blades

Cutting members for razors are provided that have a blade portion and a base portion, the blade portion having a cutting edge region terminated at a free end thereof and an opposing non-cutting edge region, the blade portion being bent relative to the base portion in a bent portion spaced from the cutting edge region and adjacent to the non-cutting edge region, wherein the bent portion extends about 108 degrees to about 115 degrees from the base portion, the bent portion having a radius of about 0.30 mm to about 0.45 mm, at least part of the cutting member having a hardness of about hardness of about 540 HV to about 750 HV, and a thickness of the bent portion is less than the average thickness of the cutting member.

Cutting members for shaving razors

Cutting members for razors are provided that have been subjected to a localized heat-treating process, e.g., application of laser energy. In some cases, the cutting members include a bent portion, and the localized heat-treating process is used to enhance ductility and thereby facilitate formation of the bent portion.
