Abstract

A saw blade includes an elongated body having a front end, a rear end, an elongated cutting edge extending between the front edge and the rear edge and defining a longitudinal axis, and a back edge opposite the cutting edge. A first tang is coupled to the rear end of the body and configured to couple the saw blade to a saw. The first tang faces a rearward direction away from the front end of the body. A second tang is defined in an intermediate portion of the body and configured to couple the saw blade to a saw. The second tang also faces the rearward direction. The second tang can be exposed by breaking off a portion of the body.

First claim

What is claimed is:

1. A saw blade comprising:
an elongated body having a front body portion and a rear body portion, each body portion having a front end, a rear end, an elongated cutting edge extending between the front end and the rear end and defining a longitudinal axis, and a back edge opposite the cutting edge;
a first tang coupled to the rear end of the rear body portion and configured to couple the saw blade to a saw, the first tang facing a rearward direction away from the front end of the rear body portion; and
a second tang defined in an intermediate portion of the body and configured to couple the saw blade to a saw, the second tang also facing the rearward direction,
wherein the intermediate portion is configured so that an entirety of the second tang can be exposed by breaking off an entirety of the rear body portion in a single integral piece from the body such that the second tang is configured to couple the front body portion to the saw after the second tang has been exposed, and
wherein, when exposed, the front end of the front body portion has a different configuration than the front end of the rear body portion.

2. The saw blade of claim 1 , wherein the intermediate portion includes a first intermediate portion and a second intermediate portion forward of the first intermediate portion, with the second tang disposed at a junction between the first intermediate portion and the rear body portion.

3. The saw blade of claim 2 , further comprising a third tang defined at a junction between the second intermediate portion of the body and the front body portion.

4. The saw blade of claim 3 , wherein an entirety of the third tang can be exposed by breaking off an entirety of the intermediate portion in a single integral piece from the front body portion.

5. The saw blade of claim 3 , wherein the second tang is rearward of the third tang.

6. The saw blade of claim 1 , wherein each cutting edge comprises a plurality of teeth that are configured to cut a workpiece only when the cutting edge is moved in a rearward direction along the longitudinal axis.

7. The saw blade of claim 1 , wherein the second tang is defined by a score in the body.

8. The saw blade of claim 7 , wherein the score includes a through-slot portion that extends through the body and a groove portion that does not extend through the body.

9. A saw blade comprising:
an elongated body having a front body portion and a rear body portion, each body portion having a front end, a rear end, an elongated cutting edge extending between the front end and the rear end and defining a longitudinal axis, and a back edge opposite the cutting edge;
a first tang coupled to the rear end of the rear body portion and configured to couple the saw blade to a saw; and
a second tang defined in an intermediate portion of the body and configured to couple the saw blade to a saw,
wherein the intermediate portion is configured so that an entirety of the second tang can be exposed by breaking off an entirety of the rear body in a single integral piece from a portion of the body that includes the first tang such that the second tang is configured to couple the front body portion to the saw after the second tang h been exposed, and
wherein, when exposed, the front end of the front body portion has a different configuration than the front end of the rear body portion.

10. The saw blade of claim 9 , wherein the intermediate portion includes a first intermediate portion and a second intermediate portion forward of the first intermediate portion with the second tang disposed at a junction between the first intermediate portion and the rear body portion.

11. The saw blade of claim 10 , further comprising a third tang defined at a junction between the second intermediate portion of the body and the front portion of the body.

12. The saw blade of claim 11 , wherein an entirety of the third tang can be exposed by breaking off an entirety of the intermediate portion in a single integral piece from the front body portion.

13. The saw blade of claim 11 , wherein the second intermediate portion is rearward of the third tang.

14. The saw blade of claim 9 , wherein each cutting edge comprises a plurality of teeth that are configured to cut a workpiece only when the cutting edge is moved in a rearward direction along the longitudinal axis.

15. The saw blade of claim 9 , wherein the second tang is defined by a score in the body.

16. The saw blade of claim 15 , wherein the score includes a through-slot portion that extends through the body and a groove portion that does not extend through the body.

17. A saw blade comprising:
an elongated body having a front body portion and a rear body portion, each body portion having a front end, a rear end, an elongated cutting edge extending between the front end and the rear end and defining a longitudinal axis, and a back edge opposite the cutting edge;
a first tang coupled to the rear end of the rear body portion and configured to couple the saw blade to a saw;
a second tang defined in an intermediate portion of the body and configured to couple the saw blade to a saw, wherein the second tang is defined by a first score in the body that has a through-slot portion that extends through the body and a groove portion that does not extend through the body such that an entirety of the second tang can be exposed by breaking off an entirety of the rear body portion from the body in a single integral piece along the score such that the second tang is configured to couple the front body portion to the saw after the second tang has been exposed, and
wherein, when exposed, the front end of the front body portion has a different configuration than the front end of the rear body portion.

18. The saw blade of claim 17 , where the through-slot portion includes a plurality of through-slots that extend through the body and the groove portion includes a plurality of grooves that do not extend through the body.

19. The saw blade of claim 17 , wherein the intermediate portion includes a first intermediate portion and a second intermediate portion forward of the first intermediate portion, with the second tang defined at a junction between the first intermediate portion and the rear body portion.

20. The saw blade of claim 19 , wherein a third tang is defined at a junction between the second intermediate portion of the body and the front body portion of the body.

21. The saw blade of claim 20 , wherein the third tang is defined by a second score in the body.

22. The saw blade of claim 21 , wherein the second score includes a through-slot portion that extends through the body and the second portion includes a groove portion that does not extend through the body.

23. The saw blade of claim 19 , wherein an entirety of the third tang can be exposed by breaking off an entirety of the intermediate portion in a single integral piece from the front body portion.

24. The saw blade of claim 17 , wherein each cutting edge comprises a plurality of teeth that are configured to cut a workpiece only when the cutting edge is moved in a rearward direction along the longitudinal axis.
