Abstract

A construction saw blade having pluralities of cutting teeth along upper and lower edge surfaces thereof, an aperture transversely extending through the blade adjacent its rearwardly facing back end of a configuration and dimension to receive a fastener to removably secure the blade to a reciprocating saw for use, and wherein each plurality of cutting teeth include rake angles for cutting substantially only on a pull stroke of the reciprocating saw.

Claims

1. A construction saw blade comprising:

a blade defined by an upper edge surface, a lower edge surface, a forwardly facing front end, and a rearwardly facing back end;

said blade also having a first plurality of cutting teeth along said upper edge surface, a second plurality of cutting teeth along said lower edge surface, and an aperture transversely extending through said blade adjacent said rearwardly facing back end;

wherein said aperture is of configuration and dimension to receive a fastening means to removably secure said blade to a reciprocating saw for use; and

wherein each of said first and second plurality of cutting teeth include rake angles for cutting substantially only on a pull-stroke of said reciprocating saw.

2. The construction saw blade of claim 1 wherein said first plurality of teeth exhibits an inverted profile of rake angles substantially identical to that of said second plurality of teeth.

3. The construction saw blade of claim 1 wherein said first plurality of teeth exhibits an inverted profile of rake angles different from that of said second plurality of teeth.

4. The construction saw blade of claim 2 wherein each of said first and second pluralities of teeth exhibit profiles of rake angles for cutting wood.

5. The construction saw blade of claim 2 wherein each of said first and second pluralities of teeth exhibit profiles of rake angles for cutting metal.

6. The construction saw blade of claim 3 wherein one of said first and second pluralities of teeth exhibits a profile of rake angles for cutting wood and wherein the other of said first and second pluralities of teeth exhibits a profile of rake angles for cutting metal.

7. The construction saw blade of claim 1 wherein said blade is manufactured of a stamped steel composition.

8. The construction saw blade of claim 1 wherein said blade is manufactured of thin flexible steel.

9. The construction saw blade of claim 1 wherein at least one of said first and second pluralities of cutting teeth include first and second individual lengths of teeth, each length being of different rake angle.
