Description:
The offset in the handle places the center of the "T" in line with the socket. A spring clip on the socket allows allows interchangeability, and the sockets can face toward or away from the handle. The ratchet portion is noted, but is not described in detail; it probably is a refinement of the J.P. Johnson patent no. 601,146.
