摘要： The invention relates to a method of thinning a coating applied on a razor blade. The method comprises providing a thinning material having a Shore OO hardness in a range of 10-100, more specifically 20-70; contacting the thinning material with an edge of the razor blade, and moving the thinning material relative to the edge of the razor blade such that a shear force is applied on the edge of the razor blade thereby removing at least a portion of the coating applied on the edge of the razor blade.

摘要： A method of making a razor cartridge including providing at least one razor blade having a cutting edge extending along a length of the razor blade and printing at least one printed object on the length is provided. The razor blade is positioned between the guard and the cap where the visible surface of the at least one razor blade includes a printed object. The printed object may extend continuously along the length of the razor blade and/or may have multiple portions having a comb-like structure. The printed object appears as a solid object to a viewer's naked eye. The solid object includes a plurality of printed ink dots not visible to the viewer's naked eye. The printed object of flexible, polymer ink may act as a guard element on the razor blade which helps with glide and to manage a user's skin (e.g., bulge) during shaving.

摘要： A razor cartridge includes a housing, a guard, a cap and a plurality of razor blades installed between the guard and cap in the housing, each blade including a base portion, a bent portion extending from an end of the base portion, and an edge portion extending from an end of the bent portion with a cutting edge formed at an end of the edge portion, wherein a first distance between a straight line extending from the front of the base portion and an end point of the cutting edge is in the range of 0.3 to 1.0 mm, wherein an overlap size defined as a distance by which the first distance of one of the razor blades is overlapped by an adjacent razor blade located behind the razor blade when the adjacent razor blade is projected in the vertical direction is less than or equal to 0.5 mm.

摘要： A method of manufacturing an edged tool on surfaces of which rusting and coloration hardly occur is provided. This method includes a plasma step which includes placing a metallic base having processed surfaces obtained by processing in a vacuum chamber, generating plasma in the vacuum chamber, and subjecting the metallic base to plasma treatment at a temperature of the metallic base adjusted to 280 to 325° C. to sharpen the processed surfaces to thereby obtain an edged tool precursor, and an oxidation step which includes reducing an internal temperature of the vacuum chamber to a specific temperature ranging from 100 to 225° C. after completion of generation of the plasma, and introducing an oxygen-containing gas into the vacuum chamber to form an oxide film on surfaces of the edged tool precursor.

摘要： A razor blade unit including a housing having a top surface, and a loop disposed on the top surface, the loop having two terminal ends and two exposed opposing edges between the two terminal ends. The loop intersects the top surface at the two terminal ends and the two terminal ends are spaced apart from each other on the top surface. At least a portion of at least one of the two exposed opposing edges has a cutting edge. The razor blade unit provides improved conformity to skin contours.

摘要： In a cutting edge of a razor blade, a non-nitrided layer containing Ti, Al, and Cr formed on opposite surfaces of a base plate as a portion of a coating layer. A remaining layer containing Ti, Al, Cr, and N formed on opposite surfaces of the non-nitrided layer as a portion of a nitrided layer of the coating layer. A surface layer containing Ti, Al, Cr, and N formed on opposite surfaces of the remaining layer as a portion of the nitrided layer of the coating layer. A fluororesin layer formed on opposite surfaces of the surface layer with a bonding layer containing Cr and Al in between. The coating layer further improves the cutting edge, enhances cutting performance of the cutting edge, and maintains the enhanced cutting performance to improve the durability of the cutting edge.
