摘要： A razor blade unit comprising a support for at least one razor blade and a surface for slidably engaging the skin of a user, and a xerogel on the surface. A process for making a sliding surface on a razor blade unit comprising applying a solution of polyurethane, a water-soluble plastic and a solvent to a surface of the razor blade unit which engages the skin of a user during shaving, and evaporating the solvent to form the sliding surface.

摘要： Metal alloys in an amorphous state are employed in the fabrication of cutting implements such as razor blades or knives. The implement may be formed from the amorphous metal or a coating of the amorphous metal may be applied. Such products may be formed from a ribbon of the amorphous metal alloy which has been prepared by quenching the molten metal or by coating the amorphous metal alloy on a suitable substrate such as by a sputtering procedure or vapor, chemical or electro-deposition of the alloy on the substrate.

摘要： The present invention relates to a cutting element having a substrate with at least one aperture which has a cutting edge along at least a portion of an inner perimeter of the aperture. The cutting edges have an asymmetric cross-sectional shape with a first face, a second face opposed to the first face and a cutting edge at the intersection of the first face and the second face. Moreover, the present invention relates to a hair removal device including such cutting elements.

摘要： A novel cutting-edge structure and method and apparatus for manufacturing the cutting-edge structure is provided. The cutting-edge structure is comprised of naturally derived or renewable material at greater than 50% by volume fraction. In one embodiment, the naturally derived material is a cellulose nanostructure such as a cellulose nanocrystal. The cellulose nanocrystal is processed using a base or mold structure to provide a cutting edge of any shape such as linear or circular edge structures. The process includes dual cure steps to produce an optimal cutting-edge structure without shrinkage. The formed cutting-edge structure can be utilized as a razor blade as it is formed with very sharp tip and edge suitable for cutting hair. The base structure can form one or more cutting-edge structures simultaneously.

摘要： A functional polymeric cutting edge structure and methods for the manufacturing of cutting edge structures comprised of polymeric materials are provided. The cutting edge structures may be produced on a substrate having a blade body or blade support type. The polymeric material is produced by curing a precursor material by electromagnetic radiation wherein a wavelength of said radiation is about double a wavelength required to cure the precursor material. A razor blade for use in a razor cartridge or a blade box may be formed using the present invention.
