Abstract (en)

The knife (1) has a convex bent cutting edge (2) whose distance is increased from a rotational axis (10) in progression direction of a contact region of the knife to a cutting material. The cutting edge is provided with a spiral-shaped outer circumferential contour. A cutting surface of front side (8) of the knife is arranged at cutting angle of 33 degrees to a main plane. A groove is arranged on the front side and radial-inwardly displaceable with respect to the cutting surface. The groove is extended along entire peripheral length of the cutting edge.
