PCT No. PCT/CH84/00006 Sec. 371 Date Sep. 11, 1984 Sec. 102(e) Date Sep. 11, 1984 PCT Filed Jan. 12, 1984 PCT Pub. No. WO84/02676 PCT Pub. Date Jul. 19, 1984.The teeth of the saw blade (1) intended for preparing wood comprise a cutting edge (2) beginning at the tip (6) and forming an angle of intersection ( delta ) of 40 DEG -55 DEG . Adjoining the cutting edge (2) at the tooth face there is a cut-back, circular curved section (3). This curved section (3) continues at the bottom into a rounded base (4) between adjacent teeth and then continues into the edge (5) bordering the gap between the teeth, and on into the back of the next tooth. A considerably increased cutting performance is achieved with a saw blade of this kind, since a paring action is effected, and the shavings can roll away easily. Saw blades equipped with this kind of teeth can be made both as circular saw blades and also as bandsaw blades which are moved in a straight line.
