ABSTRACT:
A hand tool for transmitting torque having a handle wherein a tool implement blade may be alternately mounted in three positions on the handle. A slot defined at one end of the handle permits the implement having a shaped head fixed thereon to be mounted such that the implement axis is parallel or transversely related to the handle axis, and a recess formed in the handle central region receives the implement head to permit the tool to be centrally located on the handle and transverse thereto to permit "spinning" of the implement. A retainer rotatably mounted upon the handle prevents inadvertent release of the implement from the slot and a spring biased plunger prevents inadvertent release of the implement from the central recess.
