The saw further includes a blade portion having a cutting edge that defines a plurality of cutting teeth. The cutting teeth define a repeating pattern of successive groups of teeth. Each group of teeth is less than about a half inch in length, and includes a plurality of laterally offset teeth, at least one relatively high first tooth and at least one relatively low second tooth. Prior to tooth set, the at least one relatively high first tooth is at least about 0.002 inch higher than the at least one relatively low second tooth.
