A cutting edge (15) is arranged at the line of intersection of said faces. The rake face comprises at least two adjacent, elongated ridges (14,17) which extend along at least a part of the cutting edge. A first ridge (14) connects to the cutting edge. A second (17) of said ridges is arranged to become active after wear of the first ridge. The method includes the step of wearing the first ridge to a substantial degree before activating the second ridge. |
