A reciprocating saw, including a housing, a spindle mounted for reciprocation relative to the housing, the spindle having an end adapted to receive a saw blade, the saw blade having a first orientation relative to the spindle to have a first cutting direction and a second orientation relative to the spindle to have a second cutting direction opposite the first cutting direction, and a drive assembly connected to the spindle and operable to selectively drive the saw blade along a first path of travel during a first cutting stroke and along a second path of travel during a second cutting stroke. The first path of travel is characterized by movement at least partially in the first cutting direction and the second path of travel is characterized by movement at least partially in the second cutting direction.
