Abstract: A fastener driving tool of unitary construction. The tool is characterized by a tubular grip having a fastener driving ram slidably disposed in the tube and a frictional element which maintains frictional engagement between the grip and the ram. The frictional element serves to prevent the ram from rebounding out of contact with the fastener after a blow is struck. The blow receiving end of the ram is of greater diameter than the inside diameter of the grip and comes in contact with the grip when the fastener driving end of the ram has reached the opposite end of the grip. This arrangement permits the user to determine the length of travel remaining before the fastener will be fully driven. The unitary construction of the driver is achieved by forming a detent in the grip after the grip, the ram, and the frictional element are assembled.
