1. A reciprocating saw comprising:
a housing;
a motor positioned within the housing and configured to drive a reciprocating saw blade;
a trigger configured to selectively activate the motor;
a shoe coupled to the housing and including a workpiece contact surface at a distal end thereof configured to engage a workpiece during a workpiece cutting operation;
a workpiece detection system configured to detect rearward movement of the housing away from the workpiece; and
a controller in communication with the workpiece detection system, the motor, and the trigger;
wherein, in response to the workpiece detection system detecting the rearward movement of the housing exceeding a predetermined value while the trigger is depressed, the controller is operable to deactivate the motor,
wherein the shoe is moveable relative to the housing between a retracted position, in which the shoe is configured to engage the workpiece, and an extended position in which a gap is defined between the shoe and the workpiece, in response to rearward movement of the housing; and
wherein the workpiece detection system further includes a switch operable to communicate to the controller to deactivate the motor in response to being actuated by movement of the shoe from the retracted position to the extended position.
