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.
