The blade (10) has a saw blade body (12) whose end is attached with a tooth series (14). The tooth series comprises four tetrahedrally formed cutting teeth (24) that are arranged next to each other with a space, where the four cutting teeth exhibit symmetrical square shape in cross section. Two opposite lying tetrahedrally formed tooth tips (32a, 32b) are formed with the four cutting teeth for formation of four cutting edges per four-cutting tooth. The cutting edges of the four cutting teeth form an intermediate angle of about 60 to 120 degree.
