The driver blade has a driving edge with a profile that includes driving projections, having curved contact surface for contact with curved edges of the fastener, and a relief portion therebetween that is recessed relative to both projections and contact surfaces. Further, the tool includes a lockout assembly for limiting movement of the driver blade and contact trip, thereby limiting activation of the motor.
