<p>A knife head 1, which is U- shaped in cross-section, is formed from a knife 4 and is fastened releasably to one end of a holder 2, at the other end of which a handle 3 is provided. The knife 4 projects beyond the underside of the holder 2, whereas the handle 3 protrudes beyond the upper side of the holder 2. A cutting edge 5 of the knife 4 follows the contour described by its U-shaped cross-section, extends inclined over the limb region and forms in the arc region a knife point 9. The cutting edge 5 of the knife 4 formed from a flat knife blade 4' is formed by ground surfaces 15, 16 which extend at differently acute angles to the knife blade plane. <IMAGE></p> |
