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 razor blade having a substrate with a cutting edge being defined by a sharpened tip. The substrate has thicknesses of 1.60-1.75 micrometers and 9.25-10.00 micrometers measured at a distance of four and forty micrometers from the blade tip, respectively. A ratio of the thickness measured at four micrometers to the thickness measured at forty micrometers is between 0.165-0.185. The substrate thickness is about 2.70-3.00 micrometers at eight micrometers from the blade tip, about 4.44-5.00 micrometers at sixteen micrometers from the blade tip with a thickness ratio measured at four micrometers and eight micrometers between 0.56-0.62, and a thickness ratio measured at four micrometers and sixteen micrometers between 0.32-0.40. The blade edge shape is defined by equation w=adn where “a” is between 0.50-0.62 and “n” is between 0.76-0.80. An included angle of less than 7° is measured at a distance of forty micrometers or greater from the blade tip. A nitrided substrate may also be provided.

Abstract: 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° to 135°, a facet width from 0.38 micrometers to 0.65 micrometers a wedge angle from 5° to 30°, and a thickness of between 0.8 and 1.5 micrometers measured at a distance of 1 micrometer from the blade tip.

CPC classification number: B26B21/565 , B26B21/165
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.
