TIRE RASP BLADE HAVING MULTI-CUTTING EDGES Abstract of the Disclosure: The outer edge of teeth of tire buffing machine blades is interrupted by oppositely curved arcuate slots which are cupped on centers disposed below the center on which the adjacent one of the leading and trailing deeper cutting side edges of the tooth are cupped. Between said arcuate slots, the outer edge has a shallower arcuate notch the ends of which are obtuse to the tooth outer edge. The portions of the tooth outer edge between the arcuate slots and the tooth cutting side edges are displaced laterally to opposite sides of the teeth and the inner portions of the tooth outer edge between said arcuate slots and the notch are transversely offset to the remainder of the tooth such that the teeth successively present to the tire surface being buffed a first sharply acute deeply cutting edge, then a sharply acute lighter cutting edge of shallower depth followed by an obtuse buffing edge and a more bluntly obtuse second buffing edge which act to finish the tire surface to a required texture.
