<p>The froe has wedge surfaces (4, 5) forming a base body (20) from an aluminum. The body has a striking surface (3) at one end for providing a wedge head (2). One of the surfaces is designed as a saw tooth tread (11), and the other surface is formed as a fish ridge profile (14). The surfaces are passed into an attachment surface (22) in a direction of the cutter. The attachment surface formed in an extension of the former wedge surface includes triangular trained barbs and a guide rib, which is formed in a longitudinal direction running centrally to a cutting edge (9) of a cutter.</p> |
