摘要： The invention concerns a pair of saw blades, including a first blade (1 ) and a second blade (2), which are arranged to rotate around the same rotational axis in opposite directions. Each of the blades (1, 2) has its own blade body (3, 4) and peripheral cutting elements (5, 6), wherein the blade body (3) of the first blade (1 ) has a front side, which is turned towards a back side of the blade body (4) of the second saw blade (2), and wherein the cutting elements (5, 6) form overhangs (9, 10) protruding from said front or back side. Said front and/or back side have/has a circumferential ridge (11 ), which is arranged peripherally inside of the cutting elements (5, 6) and to slide over a corresponding part or a corresponding ridge (11 ) on the opposite back side and/or front side, wherein the ridge/ridges (11 ) is/are made in one piece with the blade body (3, 4) in question and serves/serve as a spacer means to prevent the cutting elements (5, 6) with their overhangs (9, 10) to hit each other during rotation of the blades (1, 2).
