A universal joint at the angle allows force to be applied around slight corners. Supplied with a variety of sockets that snap into place in the driven head. The sockets and the rod handle store inside the hollow handle.

The drawings show a sample socket, a "standard socket driver," a screwdriver, and a "FORD valve grinder" without specifically identifying those functions.

Produced as the Billmont Masterwrench.
