Abstract: A razor cartridge having a housing including a frame with a non-cutting element, a guard and a cap. The non-cutting element has a plurality of open slots defined between a pair of projections disposed next to each other. A first razor blade is positioned between the guard and the non-cutting element and has a blade edge extending toward the guard. The non-cutting element is spaced apart from the first razor blade. A second razor blade is positioned between the non-cutting element and the cap and has a blade edge extending toward the guard. The non-cutting element is spaced apart from the second razor blade. A first rinse-through gap between the first razor blade and the non-cutting element of about 0.05 mm to about 0.5 mm. A second rinse-through gap between the second razor blade and the non-cutting of about 0.05 mm to about 0.6 mm.

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.

Abstract: A razor blade having a substrate with a cutting edge being defined by a sharpened tip. The substrate has a thickness of greater than about 2.30 micrometers measured at a distance of four micrometers from the blade tip, a thickness of greater than about 4.26 micrometers measured at a distance of eight micrometers from the blade tip, and greater than about 7.93 micrometers measured at a distance of sixteen micrometers from the blade tip. A hard coating joined to the substrate has a thickness of 700 Angstroms to about 3500 Angstroms. An outer layer joined to a coated substrate is discontinuous. The outer layer may be produced from a dispersion comprising about 0.03 g/L or less of telomer or from about 0.5 % solids or less of telomer by weight of composition. The novel razor blade cuts at less than 100 % cutting efficiency using a single fiber cutting efficiency measure.

Abstract: A razor blade having a substrate with a cutting edge being defined by a sharpened tip is provided where the substrate is comprised of a molybdenum (Mo) content of about 1.6% to about 5% by weight of composition and thicknesses of 1.60-1.75 ?m and 9.25-10.00 ?m measured at a distance of 4 and 40 ?m from the blade tip, respectively. This thickness ratio is between 0.165-0.185. The substrate thickness is about 2.70-3.00 ?m at 8 ?m from the blade tip, about 4.44-5.00 ?m at 16 ?m from the blade tip with a thickness ratio measured at 4 ?m and 8 ?m between 0.56-0.62, and a thickness ratio measured at 4 ?m and 16 ?m between 0.32-0.40. The edge shape may be defined by equation w=adn with “a” between 0.50-0.62 and “n” between 0.76-0.80. A semi-included angle less than 7° is measured at a distance of 40 ?m or greater from the blade tip. This substrate will have substantially no cracks.

Abstract: A novel razor cartridge includes at least one non-cutting element disposed anywhere within a blade array between a guard and a cap and/or in a blade position of a frame providing skin/hair management. This non-cutting element allows the fine-tuning of parameters such as blade-skin contact, hair orientation, blade spans and rinse-through gaps in manners that improve shaving comfort, closeness, efficiency, and/or rinse-ability. The non-cutting element may include projections, fin-like elements, comb-like features having teeth, exfoliation or lubricating capabilities. By having a fixed non-cutting element disposed midway in a blade array, a multi-stage cartridge is provided with a middle control point with potentially different functionality before and after the non-cutting element. The non-cutting element is not attached to another blade in the blade array though it may be manufactured as a modified blade support, attached to a blade support, or as part of the frame or the clips.
