ABSTRACT:
A reciprocating saw blade moved in opposite directions parallel to a longitudinal axis is formed with at least one row of longitudinally succeeding teeth having tips all lying on a common tip line parallel to the longitudinal axis and including even teeth all oriented in one direction parallel to the axis and odd teeth alternating with the even teeth and all oriented in the opposite direction parallel to the axis. Each even tooth forms with one of the adjacent odd teeth a double tooth and the tips of the teeth of each double tooth are set laterally of the blade to one side with the lateral set by an offset that alternates longitudinally from double tooth to double tooth to opposite sides of a center blade plane. The offset is the same for all teeth. Each tooth has a relatively steep leading edge and a relatively shallow trailing edge, relative of course to the respective longitudinal direction.
