    摘要： The invention relates to a cutting member (7) comprising a plate-shaped substrate (19) on which a tip (27) is provided which is bounded by a cutting edge (9). According to the invention, the tip comprises an ultimate tip (31) and a basic tip (33), the ultimate tip extending from the cutting edge over a distance d1 and having a profile which at least approximates the equation w = a1.dn1, and the basic tip connecting to the ultimate tip and having a profile which at least approximates the equation w = a.(d+R)n, where w is a profile thickness (in µm) and d is a distance (in µm) from the cutting edge (9), and n1 is smaller than n, and a1 = a.(d1+R)n/d1n1. In this manner, the profile of the ultimate tip is relatively robust and the profile of the basic tip is relatively slender, as a result of which the cutting member has a comparatively high resistance to wear, and the cutting forces of the cutting member are comparatively small. In a preferred embodiment, n1 = n.d1/(R+d1), resulting in the basic tip (33) connecting to the ultimate tip (31) without a kink, so that the cutting forces are further reduced. In another preferred embodiment, the ultimate tip and the basic tip comprise a coating (35) made from a material, for example diamond-like carbon, having a higher modulus of elasticity than the material from which the substrate (19) is made. The cutting member (7) is used as a shaving blade in a shaver (1) according to the invention.

    摘要： Cutting edges, particularly of razor blades, are coated with PTFE by spraying the edge with an aqueous dispersion of PTFE of molecular weight at least 500,000; subjecting the coated edge to an ionising radiation dose of up to 50 Mrads in the presence of oxygen; and then sintering the coating.

    摘要： A razor blade includes a substrate (50) with a wedge-shaped edge at a distance of forty micrometers from the sharpened tip (52), and a layer of diamond or diamond-like material (60) defined by facets (66, 68) that have an included angle of less than seventeen degrees that has a thickness of at least twelve hundred angstroms from the sharpened tip (52) of said substrate (50) to a distance of forty micrometer from the sharpened tip (52), and an ultimate tip defined by facets (62, 64) that have lengths of at least about 0.1 micrometer and define an included angle of at least sixty degrees, and that defines a tip radius of less than about 400 angstroms, an aspect ratio in the range of 1:1-3:1, a hardness of at least thirteen gigapascals and an L5 wet wool felt cutter force of less than 0.8 kilogram.
