Abstract

A method of using a reciprocating saw blade having an elongated body with a front body portion and a rear body portion, each having a front end, a rear end, an elongated cutting edge extending between the front and rear ends and a back edge opposite the cutting edge. A first tang that extends from the rear end of the rear body portion may be coupled to a reciprocating saw. The saw blade may be removed from reciprocating saw, and a second tang, which extends from the rear end of the front body portion, may be exposed by breaking off an entirety of the rear body portion in a single integral piece from the front body portion. The front body portion, without the rear body portion, may be coupled to the reciprocating saw by coupling the exposed second tang to the reciprocating saw.

First claim

What is claimed is:

1. A method of using a reciprocating saw blade comprising:
providing a reciprocating saw blade having an elongated body with a front end, a rear end, an elongated cutting edge extending between the front end and the rear end, an elongated back edge opposite the cutting edge, and a first tang coupled to the rear end and facing a rearward direction away from the front end, the body having a first body portion adjacent the rear end of the saw blade and a second body portion forward of the first body portion;
coupling the saw blade to a reciprocating saw by coupling the first tang to the reciprocating saw;
removing the saw blade from the reciprocating saw by removing the first tang from the reciprocating saw;
removing an entirety of the first body portion in a single integral piece without any additional pieces from the second body portion to expose an entirety of a second tang that is coupled to a rearward end of the second body portion and that faces the rearward direction;
coupling the second body portion of the saw blade, without the first body portion, to the reciprocating saw by coupling the second tang to the reciprocating saw.

2. The method of claim 1 , further comprising:
removing from the second body portion of the saw blade from the reciprocating saw by removing the second tang from the reciprocating saw;
removing the second body portion in a single integral piece from a third body portion of the saw blade, disposed frontward of and adjacent the second body portion, to expose a third tang that is coupled to a rearward end of the third body portion and that faces the rearward direction;
coupling the third body portion, without the first and second body portions, to the reciprocating saw by coupling the third tang to the reciprocating saw.

3. The method of claim 1 , wherein cutting edge comprises a plurality of teeth that are configured to cut a workpiece only when the cutting edge is moved in the rearward direction.

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

5. The method of claim 4 , wherein the score includes a through-slot portion that extends through the body and a groove portion that does not extend through the body.

6. The method of claim 1 , wherein after removing the first body portion from the second body portion, the front end of the saw blade has a different configuration than a front end of the first body portion.

7. The method of claim 1 , further comprising cutting a workpiece using teeth on the first body portion when the first tang is coupled to the reciprocating saw.

8. The method of claim 7 , further comprising cutting a workpiece using teeth on the second body portion when the second tang is coupled to the reciprocating saw.

9. A method of using a reciprocating saw blade comprising:
providing a reciprocating saw blade having an elongated body with 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 a back edge opposite the cutting edge;
coupling the saw blade to a reciprocating saw by coupling a first tang that extends from the rear end of the rear body portion to the reciprocating saw;
removing the saw blade from the reciprocating saw by removing the first tang from the reciprocating saw;
exposing an entirety of a second tang, which extends from the rear end of the front body portion, by breaking off an entirety of the rear body portion in a single integral piece without any additional pieces from the front body portion;
coupling the front body portion of the saw blade, without the rear body portion, to the reciprocating saw by coupling the exposed second tang to the reciprocating saw.

10. The method of claim 9 , wherein the front body portion includes a first intermediate portion that includes the rear end of the front body portion and a second intermediate portion forward of the first intermediate portion.

11. The method of claim 10 , further comprising removing the front body portion of the saw blade from the reciprocating saw, exposing a third tang, which extends from a rear end of the second intermediate body portion, by breaking off an entirety of the first intermediate body portion in a single integral piece from the second intermediate body portion, and coupling the second intermediate body portion, without the first intermediate body portion and the rear body portion, to the reciprocating saw by coupling the exposed second tang to the reciprocating saw.

12. The method of claim 9 , wherein cutting edge comprises a plurality of teeth that are configured to cut a workpiece only when the cutting edge is moved in the rearward direction.

13. The method of claim 12 , wherein the score includes a through-slot portion that extends through the body and a groove portion that does not extend through the body.

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

15. The method of claim 9 , wherein after removing the rear body portion from the front body portion, the front end of the saw blade has a different configuration than a front end of the rear body portion.

16. A method of using a reciprocating saw blade comprising:
providing a reciprocating saw blade having an elongated body with 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 a back edge opposite the cutting edge;
coupling the saw blade to a reciprocating saw by coupling a first tang that is coupled to the rear end of the rear body portion to the reciprocating saw;
removing the saw blade from the reciprocating saw by removing the first tang from the reciprocating saw;
exposing an entirety of a second tang, which is coupled to the rear end of the front body portion and is defined by a first score in the body, by breaking off an entirety of the rear body portion in a single integral piece without any additional pieces from the front body portion, the first score having a through-slot portion that extends through the body and a groove portion that does not extend through the body;
coupling the front body portion of the saw blade, without the rear body portion, to the reciprocating saw by coupling the exposed second tang to the reciprocating saw.

17. The method of claim 16 , wherein the front body portion includes a first intermediate portion that includes the rear end of the front body portion and a second intermediate portion forward of the first intermediate portion, and further comprising removing the front body portion of the saw blade from the reciprocating saw, exposing a third tang coupled to the second intermediate portion by breaking off an entirety of the first intermediate body portion in a single integral piece from the second intermediate body portion, and coupling the second intermediate body portion, without the first intermediate body portion and the rear body portion, to the reciprocating saw by coupling the exposed second tang to the reciprocating saw.

18. The method of claim 16 , wherein cutting edge comprises a plurality of teeth that are configured to cut a workpiece only when the cutting edge is moved in the rearward direction.

19. The method of claim 16 , wherein the second tang is defined by a second score in the saw blade having a through-slot portion that extends through the body and a groove portion that does not extend through the body.
