<p>A multi-chip facet cutting saw blade is provided together with a method for cutting a work piece. The saw blade comprises a plurality of cutting teeth defining a substantially central plane, a cutting direction, and a repeating tooth pattern 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; (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; 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; and first means for creating cutting forces that are directed laterally inwardly substantially toward the central plane and, in turn, forming a substantially straight cut through a workpiece.
