Abstract

A saw blade blank includes a body having an edge and an attachment portion formed on the body. The attachment portion is configured to connect to a power tool. A first portion of the edge is set in a first direction relative to the body. A second portion of the edge is set in a second direction opposite the first direction relative to the body. No cutting teeth are formed on the edge of the body.

First claim

What is claimed is:

1. A saw blade blank comprising:
a body having an edge; and
an attachment portion formed on the body, the attachment portion configured to connect to a power tool;
wherein a first portion of the edge is set in a first direction relative to the body, wherein a second portion of the edge is set in a second direction opposite the first direction relative to the body, and wherein no cutting teeth are formed on the edge of the body; and
wherein the edge of the body includes a series of portions set in alternating directions relative to the body.

2. The saw blade blank of claim 1 , wherein a transition between the first portion of the edge and the second portion of the edge is radiused.

3. The saw blade blank of claim 1 , wherein a transition between the first portion of the edge and the second portion of the edge is abrupt.

4. The saw blade blank of claim 1 , wherein the first portion of the edge has a first set magnitude, wherein the second portion of the edge has a second set magnitude, and wherein the first and second set magnitudes are generally equal.

5. The saw blade blank of claim 1 , wherein the first portion of the edge has a first set magnitude, wherein the second portion of the edge has a second set magnitude, and wherein the first and second set magnitudes are different.

6. The saw blade blank of claim 1 , wherein a length of the first portion of the edge and a length of the second portion of the edge are generally the same.

7. The saw blade blank of claim 1 , wherein the attachment portion includes a tang and an aperture.

8. The saw blade blank of claim 7 , further comprising a tip formed on the body opposite from the attachment portion.

9. The saw blade blank of claim 1 , wherein a third portion of the edge is unset relative to the body.

10. The saw blade blank of claim 9 , wherein the third portion of the edge is located directly between the first portion of the edge and the second portion of the edge.

11. The saw blade blank of claim 1 , wherein the body has an overall shape of a finished saw blade, without cutting teeth.

12. The saw blade blank of claim 11 , wherein the overall shape is the overall shape of a reciprocating saw blade.

13. A saw blade blank comprising:
a body having an edge;
an attachment portion formed on the body, the attachment portion including a tang and an aperture, the attachment portion configured to connect to a power tool; and
a tip formed on the body opposite from the attachment portion;
wherein a first portion of the edge is set in a first direction relative to the body, wherein a second portion of the edge is set in a second direction opposite the first direction relative to the body, and wherein no cutting teeth are formed on the edge of the body.

14. The saw blade blank of claim 13 , wherein a third portion of the edge is unset relative to the body.

15. The saw blade blank of claim 14 , wherein the third portion of the edge is located directly between the first portion of the edge and the second portion of the edge.

16. The saw blade blank of claim 13 , wherein the body has an overall shape of a finished saw blade, without cutting teeth.

17. A saw blade blank comprising:
a body having an edge; and
an attachment portion formed on the body, the attachment portion configured to connect to a power tool;
wherein a first portion of the edge is set in a first direction relative to the body, wherein a second portion of the edge is set in a second direction opposite the first direction relative to the body, wherein a third portion of the edge is unset relative to the body, and wherein no cutting teeth are formed on the edge of the body.

18. The saw blade blank of claim 17 , wherein the third portion of the edge is located directly between the first portion of the edge and the second portion of the edge.

19. The saw blade blank of claim 17 , wherein the first portion of the edge has a first set magnitude, wherein the second portion of the edge has a second set magnitude, and wherein the first and second set magnitudes are generally equal.

20. The saw blade blank of claim 17 , wherein the first portion of the edge has a first set magnitude, wherein the second portion of the edge has a second set magnitude, and wherein the first and second set magnitudes are different.
