Abstract

A double edged sabre saw blade having oppositely disposed cutting edges, said cutting edges having a non-parallel relation converging in the direction of the free end of said blade to form a pointed plunge cutting end portion, said cutting edges each being adapted to cut in a direction oppositely that of the other.

Claims

1. A reciprocating saw blade structure comprising a main body portion of a saw blade, a shank portion of said blade, said blade having oppositely disposed cutting edges. said cutting edges each diverging from the longitudinal axis of said blade in the direction of said shank portion and converging toward the free end portion of said blade forming a pointed plunge cutting portion, said cutting edges comprising teeth, said teeth of each of said edges adapted to cut in a direction reversely that of the other, and said teeth having close proximity to one another at said plunge cutting end portion.

2. The structure set forth in claim 1, said cutting edges each diverging from said longitudinal axis of said blade in the range of 3* - 7*.
