Abstract

A multi-tool includes a pair of plates having respective handle portions, joint portions, and head portions, with the plates pivotally connected to each other at the joint portions, and to be pivoted relative to each other to establish an open position and a closed position of the plates. A bit holder is extended from an end of one of the plates, with the bit holder including a socket to receive an insert bit, the handle portion of the one of the plates including a storage area to receive and store the insert bit, and, in the closed position of the plates, the plates to overlap each other with the handle portion of the other of the plates to cover the storage area and the handle portion of the one of the plates.
