Abstract:
1. A saw blade comprising: a plurality of cutting teeth defining a cutting direction, and a repeating pattern of non-overlapping groups of successive teeth, each group including (1) a first tooth defining a first laterally-extending upper surface having a first width and a first height, and first side surfaces extending laterally and downwardly on opposite sides of the first upper surface relative to each other at first acute angles relative to the first upper surface; (2) a second tooth located rearwardly of the first tooth with respect to the cutting direction of the saw blade, and including a second laterally-extending upper surface defining a second width and a second height, and second side surfaces extending laterally and downwardly on opposite sides of the second upper surface relative to each other at second acute angles relative to the second upper surface; and (3) a third tooth located rearwardly of the first and second teeth with respect to the cutting direction of the saw blade, and including a third laterally-extending upper surface defining a third width and a third height, and third side surfaces extending laterally and downwardly on opposite sides of the third upper surface relative to each other at third acute angles relative to the third upper surface; and wherein the first height is greater than the second and third heights, the first width is less than the second and third widths, and the first acute angle is greater than the second and third acute angles.
