A wood cutting band saw blade (10) includes a cutting edge (14) and a back edge (16), wherein the cutting edge is defined by a plurality of teeth (17, 17') spaced relative to each other. The plurality of teeth include a plurality of set teeth each having a tip (20, 20'), each defining a bend plane (18), and each including a shelf (30, 30') located at least partially between the tip and the bend plane for reducing saw dust passing to the kerf and accumulating on the band saw blade. Each of the set teeth may define a relief surface (244', 244'') and a cutting surface (224', 224'') where the relief surface extends from one side of the tip in a direction opposite that of the movement of the band saw blade and the cutting surface extends from another side of the tip. The shelf includes a shelf surface (34, 34') extending from the cutting surface (24, 24') and may terminate in a shelf tip (36, 36'). |
