ABSTRACT:
An improved ratchet wrench is provided which includes an elongated handle, a circular head portion connected to the handle, a socket formed in the head portion, and a ratchet mechanism mounted within the socket. To provide increased strength characteristics, an internal core member, formed of steel, extends lengthwise within the handle and around the head portion. To provide improved insulating characteristics, an external housing, formed of rigid plastic material, completely encloses and insulates the internal steel core member.
