<p>The wood working machine blade (1) can be resharpened and has ridges along the chip removal surface. These are in the form of a bend, made by bending on each side of a cut at an angle of 90 degrees. The bend (4) is formed to the right or left of the cut (5). The edge of the ridge (6) of the bend (8) forms, around the edge, a cutting surface which joins, without interruption, the adjacent cutting edge (2) of the blade (1). The bend passes, slightly to the right or left of the cutting edge.</p> |
