A reciprocating saw including a first end, a working end opposite the first end, and a housing extending between the first end and the working end. A reciprocating shaft is supported within the housing and has a longitudinal axis. A locking mechanism is supported at the housing and is selectively moveable between a first position and a second position. When the locking mechanism is in the first position the reciprocating shaft is configured to substantially reciprocate relative to the housing but remain substantially rotationally fixed relative to the longitudinal axis of the reciprocating shaft. When the locking mechanism is in the second position, the reciprocating shaft is configured to substantially reciprocate relative to the housing and at the same time substantially rotate about the longitudinal axis of the reciprocating shaft independent of the housing.
