<p>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.</p> |
