Saw blade
First Claim
1. A reciprocating saw blade, comprising:
- an elongated substantially flat member having a first end and a distal second end, a longitudinal back edge and a longitudinal cutting edge; and
a plurality of alternately and oppositely facing slicing teeth defining a plurality of gullets therebetween, the plurality of slicing teeth comprising a first plurality of slicing teeth extending a predetermined distance from the first end toward the second end and merging into a second plurality of slicing teeth extending to the second end, each slicing tooth ofthe plurality of slicing teeth comprising;
a tip including an uppermost planar surface;
a slicing face facing the first end and extending from the tip to a respective bottom of one of the gullets; and
a planing face facing the second end and extending from the tip to a respective bottom of another of the gullets;
wherein the tips of the second plurality of teeth define a first tooth tip tangent line and each of the uppermost planar surfaces of the second plurality of teeth lies at an incline angle relative to the first tooth tip tangent line, and further wherein each of the uppermost planar surfaces of the first plurality of teeth lies at a smaller angle relative to the first tooth tip tangent line than each of the incline angles.

Abstract
A reciprocating saw blade comprises an elongated substantially flat body having a tang end and a distal tip end, a back edge and a spaced apart cutting edge. The cutting edge is formed of first and second pluralities of alternately and oppositely facing slicing teeth which define gullets formed therebetween. The first plurality of the slicing teeth extends from the one end and merges into the second plurality of the slicing teeth which extends to the other end. Each slicing tooth includes a slicing face facing one end, a planing face facing the other end, and a tip including an uppermost planar surface. The tips of the second plurality of teeth are substantially tangent to a first tooth tip tangent line. Each tip surface of the second plurality of teeth lies at a greater angle to the first tip tangent line than the tip surface of the first plurality of teeth. A method of making a reciprocating saw blade in accordance with the present invention is also disclosed.
