Abstract: A razor blade with a substrate having a tip portion. A hard coating layer is deposited on the substrate. A non-fluorinated organic material is deposited in one or more monolayers on an outer bonding surface of the hard coating. The hard coating layer has an aspect ratio of (a) to (b) of at least 1.5:1, wherein (a) is a first distance from a tip defined by the hard coating layer to the tip portion of the substrate, and (b) is a second distance from an outer surface of the hard coating layer to an underlying surface of the substrate.

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

Abstract: A razor cartridge is provided comprising: a housing and a blade assembly mounted to the housing. The blade assembly may comprise at least one razor blade defined by a substrate comprising a first portion and a second portion. The first portion may comprise first and second outer surfaces. The second portion may comprise first and second sections separated by a split line. The first section may comprise a first facet and an end 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. A shoulder may be positioned between the first facet and the end facet of the first section and define a skin-contacting surface.

Abstract: The present invention relates to razor blade cutting edges and methods of producing edges exhibiting improved shave performance longevity and lower cutting forces. Conventional razor blades have increasing cutting forces with use due to the outer coating wear and adhesion loss. Blade edges produced according to the novel process exhibit significantly lower cutting forces when subjected to wool felt cutting shaving simulation, which correlates to more comfortable shaves initially and over the life of the blades. The present invention treats razor blade edges having a first adherent polyfluorocarbon coating with a first solvent to partially remove the polyfluorocarbon coating, adds a second polyfluorocarbon coating, heats, and treats the blade edge with a second solvent providing a final blade edge having a thin, uniform polyfluorocarbon coating. Preferred solvents include perfluoroalkanes, perfluorocycloalkanes, and perfluoroaromatic compounds having a critical temperature or boiling point above the dissolution temperature for the polyfluorocarbon in the solvent.

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.
