<p>A reciprocating saw blade for use with a reciprocating saw having a movable shoe includes a main body including a first end configured to attach to the reciprocating saw, a first edge, and a second edge opposite the first edge. The main body includes a plurality of coarse teeth and a plurality of fine teeth defined in the first edge, the coarse teeth extending along a length in the first edge near a center of the main body and the fine teeth being defined in the first edge on both sides of the coarse teeth. A first indicator is positioned on the main body adjacent the first edge and substantially aligned with a center of the length to indicate the center of the coarse teeth and a plurality of second indicators is positioned on the main body adjacent the second edge. Each of the plurality of second indicators is spaced a different distance from the first indicator than any of the other of the plurality of second indicators. Each distance corresponds to a size of a workpiece. Each of the plurality of second indicators is positioned between the first indicator and the first end such that no indicators are positioned on the side of the first indicator opposite the first end. Alignment of the shoe with any one of the plurality of second indicators aligns the first indicator with a center of a workpiece having a size corresponding to the selected one of the plurality of second indicators.</p> |
