Abstract

A reciprocating saw blade for use with a reciprocating saw, the saw blade including a body including a first substantially planar surface and a second substantially planar surface opposite the first surface, an attachment portion for coupling the saw blade to the reciprocating saw, a cutting edge including a plurality of cutting teeth, and a rib element including a pair of outermost rib members. One of the outermost rib members is proximate the cutting edge and the other of the outermost rib members is proximate a back edge of the blade opposite the cutting edge. Each outermost rib member includes a first portion and a second portion. The first portions of each of the ribs are substantially parallel to one another.

First claim

The invention claimed is:

1. A reciprocating saw blade for use with a reciprocating saw, the saw blade comprising:
a body including a first substantially planar surface and a second substantially planar surface opposite the first surface;
an attachment portion including a tang and an aperture for coupling the saw blade to the reciprocating saw;
a cutting edge including a plurality of cutting teeth; and
a rib arrangement including a pair of rib members, each rib member being raised relative to the first substantially planar surface, one of the rib members being proximate the cutting edge and the other of the rib members being proximate a back edge of the blade opposite the cutting edge, each rib member including a first portion and a second portion, the first portion of each of the rib members extending along the attachment portion proximate the aperture, the first portions being substantially parallel to one another and located on opposing sides of the aperture so that the aperture is disposed between the first portions, the second portion of each of the rib members extending along at least a portion of the body, the second portion of each rib member being angled relative to the first portion of the rib member, and the second portion of each rib member extending parallel to an edge of the body;
wherein the rib arrangement further includes an interior rib member positioned between the rib members, the interior rib including a first portion that is parallel to the first portion of the rib members.

2. The reciprocating saw blade of claim 1 , each of the rib members including an intermediate portion extending between the first portion and the second portion, the intermediate portion of one of the rib members extending away from the intermediate portion of the other rib member.

3. The reciprocating saw blade of claim 1 , wherein each rib member is raised relative to the first substantially planar surface by a distance that is approximately 0.015 inches.

4. The reciprocating saw blade of claim 1 , wherein the aperture is substantially circular.

5. The reciprocating saw blade of claim 1 , wherein the rib members form protrusions on the first substantially planar surface, and form cavities on the second substantially planar surface.

6. The reciprocating saw blade of claim 1 , wherein the attachment portion is angled relative to the saw blade body.

7. The reciprocating saw blade of claim 1 , wherein the attachment portion has a first length measured from a top edge to a bottom edge, and the saw body has a second length measured from the cutting edge to the back edge, and wherein the first length is less than the second length.

8. The reciprocating saw blade of claim 1 , wherein the tang includes a first tang member and a second tang member, and wherein the first portion of one of the rib members is proximate the first tang member.
