The outer grip of the handle can rotate freely, or be firmly linked to the shaft by an internal pin and spring / ball detent. This construction allows the piece to be used as a "nut driver" handle (figs. 4 & 7) or as an extension shaft for ratchet or other drive tool (figs. 3 & 6). The handle end of the shaft has a square socket for such drive tool (figs. 2 & 5).
