Abstract
A reciprocating saw blade that includes an elongated blade body defining an inner end and a distal end, a cutting edge located on one side of the blade body and extending between the inner and distal ends thereof and a tang located at the inner end of the blade body. The tang projects from the blade body at an acute angle of at least about 3° relative to a line tangent to an inner end of the cutting edge. The cutting edge includes a portion defining a substantially curved contour and optionally can include at least one further portion defining a non-curved contour.
Claims20
A reciprocating saw blade, comprising:
- an elongated blade body defining an inner end and a distal end;
- a tang located at the inner end of the blade body;
- a cutting edge located on one side of the blade body and an opposing edge located on an opposite side of the blade body, the cutting edge and the opposing edge each extending from the inner end of the blade body to the distal end of the blade body, the cutting edge comprising:
- a first cutting edge portion comprising a first substantially straight cutting edge extending from the inner end of the blade body towards a second cutting edge portion;
- the second cutting edge portion disposed adjacent the first cutting edge portion and comprising a curved cutting edge curved toward the opposing edge of the blade body;
- and
- a third cutting edge portion comprising a second substantially straight cutting edge extending from the second cutting edge portion towards the distal end of the blade body.
