ABSTRACT:
A socket wrench comprises a ratchet head which is removably held in an aperture in the forward end of a ratchet handle. A knurled drive ring allows the ratchet head to be used when detached from the handle and the handle itself is hollow and receives a tray which is dimensioned to hold a plurality of sockets. Access to the sockets is obtained by withdrawing the tray from the handle.
