Abstract

A reciprocating saw blade includes an elongated blade body extending along a blade axis and having a rear end, a front end, a cutting edge having a plurality of teeth, a non-cutting edge opposite the cutting edge; and a tang coupled to the rear end and configured to be received in a blade holder of a powered reciprocating saw. The cutting edge includes inclined and declined cutting edge portions. The inclined cutting edge portion extends away from the blade axis and toward the front end at an acute first angle and extends from a first tooth to a second tooth. The first tooth is closer to the rear end and closer to the blade axis than the second tooth. The declined cutting edge portion extends toward the blade axis and toward the front end at an acute second angle that is greater than the first angle and extends from a third tooth to the first tooth. The first tooth is closer to the front end and closer to the blade axis than the third tooth.
