Abstract: A gas spring-powered fastener driver includes a cylinder, a moveable piston positioned within the cylinder, and a driver blade attached to the piston and movable therewith between a top-dead-center (TDC) position and a driven or bottom-dead-center (BDC) position. The driver blade includes a body and a plurality of teeth extending therefrom. The driver blade defines a driving axis. The gas spring-powered fastener driver further includes a lifter operable to move the driver blade from the BDC position toward the TDC position. Each one of the plurality of teeth includes a contact surface engageable with the lifter. The contact surface of each tooth defines an included angle with the driving axis that is greater than 90 degrees.
