Abstract

A double sided saw blade for operable engagement with a powered drive unit such as a reciprocating saw, comprises a thin elongated metal blade having opposed longitudinal side edges provided with first and second parallel saw tooth cutting edges. A handle element is secured to the blade and includes a mechanism for securing the handle to the powered drive unit.

Claims

1. A saw blade for operable engagement with a powered drive unit, comprising:

a thin elongated metal strip having opposed longitudinal side edges provided with first and second parallel saw tooth cutting edges;

a handle element, said handle element including means for securing said handle element to said thin elongated metal strip;

means for operably securing said handle element to a powered drive unit.

2. The saw blade of claim 1, wherein said means for securing said handle element to said thin elongated metal strip comprises a pair of apertures sized to secure a pair of bolts and locking nuts thereto.

3. The saw blade of claim 1, wherein said powered drive unit is a reciprocating saw.

4. The saw blade of claim 1, wherein said means for operably securing said handle element to said powered drive unit comprises an extension element with an aperture therein for operable attachment to said powered drive unit.

5. The saw blade of claim 1, further including means for reversibly securing said thin elongated metal strip to said handle element to allow alternative use of said first and second cutting edges.

6. The saw blade of claim 1, wherein said first and said second cutting edges have a different pitch.

7. A device for operable engagement with a powered reciprocating saw, comprising:

a thin elongated metal blade having opposed longitudinal side edges provided with first and second parallel saw tooth cutting edges;

a handle element, said handle element including means for securing said handle element to said thin elongated metal blade;

means for operably securing said handle element to said powered reciprocating saw.

8. The device of claim 7, wherein said means for securing said handle element to said thin elongated metal blade comprises a pair of apertures sized to secure a pair of bolts and locking nuts thereto.

9. The device of claim 7, wherein said powered reciprocating saw is a hand held powered reciprocating saw.

10. The device of claim 7, wherein said means for operably securing said handle element to said powered reciprocating saw comprises an extension element with an aperture therein for operable attachment to said powered reciprocating saw.

11. The device of claim 7, further including means for reversibly securing said thin elongated metal blade to said handle element to allow alternative use of said first and second cutting edges.

12. The device of claim 7, wherein said first and said second cutting edges have a different pitch.
