Abstract: A method of applying a lubricious coating of a material such as a fluoropolymer to a cutting edge of a blade includes providing the blade having the cutting edge including a tip end, a first facet, and a second facet with the first facet and the second facet adjacent the tip end. The method further includes generating a plasma stream and directing the plasma stream towards the cutting edge. The method further includes introducing a fluid stream containing a dispersion including the fluoropolymer into the plasma stream, thereby simultaneously plasma treating the cutting edge and depositing solids of the dispersion onto the cutting edge.

Abstract: A razor cartridge has a housing with a blade mounting region between a guard and a cap. A first and a second razor blade are sequentially mounted in the blade mounting region with an intermediate non-cutting and skin engaging structure between the blades. The intermediate structure has a leading edge region closest the guard and at or adjacent a skin engaging surface of the intermediate structure. The leading edge region of the intermediate structure has an elastomeric linear seal contacting the first razor blade to seal any gap between the intermediate structure and the first blade.

Abstract: A method for making a bent razor blade is disclosed. The method includes: providing an elongated strip of stainless steel that can be 0.076 mm thick; hardening the strip; providing a cutting edge along an edge of the strip and providing coating(s) on the cutting edge. The stainless steel has a carbon content less than 0.60% and preferably between 0.45% and 0.55% by weight. The strip is separated lengthwise into discrete razor blades. The bent portion of the razor blade is then formed using a swivel bending process.
