Abstract: The invention relates to a cutting member (7) includes 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 includes 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 ?m) and d is a distance (in ?m) 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 one example, n1=n.

Abstract: Method of applying a marking or image on a substrate which is provided with a coating by means of a sol-gel process. After the application of a layer of a sol-gel solution on the substrate, an ink which is compatible with the sol-gel is applied on the wet layer. The ink penetrates into the layer and then the layer is cured to form the coating.
