Saw blade

A reciprocating saw blade for use with a reciprocating saw, the reciprocating saw blade comprising:

• a body defining a longitudinal axis;
• a cutting portion formed on the body, the cutting portion including a plurality of cutting teeth, each cutting tooth including a tip and a protrusion, each tip spaced a separation distance from a corresponding protrusion in a direction perpendicular to the longitudinal axis, wherein the separation distance is measured from a distal end of the tip of one cutting tooth to a distal end of the protrusion of the same cutting tooth, a protrusion of a first cutting tooth spaced a gap distance from a tip of an adjacent second cutting tooth in a direction parallel to the longitudinal axis;
• wherein the gap distance is measured from the distal end of the protrusion of one cutting tooth to the distal end of the tip of an adjacent cutting tooth;
• wherein a ratio of the separation distance to the gap distance is at least 0.4 and no greater than 0.5;
• and
• wherein the protrusion of the first cutting tooth is spaced a second gap distance from the tip of the first cutting tooth in a direction parallel to the longitudinal axis, and wherein a ratio of the second gap distance to the gap distance is approximately 1.5.
