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, 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.

Abstract: Razors cartridges including a guard, a cap, and at least two blades with parallel sharpened edges located between the guard and cap are provided. The first blade has a first color and a second blade has a second color, where the first color is different than the second color. The blade color corresponds to an attribute of the blade (e.g., low cut force) that the color is disposed on or an attribute of the razor cartridge (e.g., sensitive skin). The color of the blade corresponds to a target user of the razor cartridge (e.g., male or female). The first blade defines a blade edge near or nearest the guard and a second blade defines a blade edge near or nearest the cap.

Abstract: 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.

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.

Abstract: A cutting member for a shaving razor includes an elongated blade portion that tapers to a cutting edge, an elongated base portion that is integral with the blade portion, and a bent portion, intermediate the blade portion and the base portion. In some implementations, at least part of the cutting member has a thickness of at least about 0.005 inch (0.127 millimeter).

Abstract: Razors cartridges including a guard, a cap, and at least two blades with parallel sharpened edges located between the guard and cap are provided. A first blade defines a blade edge nearest the guard and a second blade defines a blade edge nearest the cap. The first blade has a cutter force less than the cutter force of the second blade.

Abstract: Razors are described herein. In some instances the razors include a safety razor blade unit that includes a guard, a cap, and at least two blades with parallel sharpened edges located between the guard and cap. A first blade defines a blade edge nearer the guard and a second blade defines a blade edge nearer the cap. The first blade has a cutter force greater than the cutter force of the second blade. In some instances the razors provide a comfortable shave having improved closeness.
