摘要： A razor blade having a substrate with a cutting edge being defined by a sharpened tip and novel dimensions is provided. The substrate has dimensions of volumes, cross-sectional areas, and thicknesses at or near the ultimate tip (e.g., at a distance up to about 2 micrometers from the sharpened tip). The substrate is coated with one or more materials and has novel volumes, cross-sectional areas, and thicknesses at or near the ultimate tip (e.g., at a distance up to about 2 micrometers from the sharpened tip). The total area of the substrate at 2 micrometers back from the ultimate tip is at or below about 1.093 square micrometers and at or below about 6.511 square micrometers for a coated substrate at the same distance. These dimensional values are measured robustly with an atomic force microscope and provide reduced cut forces for improved blade performance.

These dimensional values are measured robustly with an atomic force microscope and provide reduced cut forces for improved blade performance.

摘要： 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.

摘要： 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, in which the first and second outer sides converge at a tip, the first outer side comprises a first coating disposed substantially thereon and extending from the tip region toward the base, and a first portion of the second outer side is substantially free of any coating, the first portion extending from the tip region toward the base or being spaced apart from the tip region and the base. Also provided is a method of coating the razor blade.

摘要： A razor cartridge including a housing; a trailing blade assembly mounted to the housing and including a trailing blade with a blade tip; a leading blade assembly mounted to the housing in front of the trailing blade assembly and including a leading blade with a blade tip; and a skin support element affixed to the leading blade assembly and extending towards the blade tip of the trailing blade assembly. A horizontal length of the skin support element may be greater than a distance from a trailing part of the skin support element to the blade tip of the trailing blade assembly.
