Abstract: A tool assembly includes a multi-purpose tool, an adaptor and a socket wrench. The multi-purpose tool includes a body that contains implements such as knives, openers, scissors and other such devices. A fixed plier jaw extends from the body, and a movable plier jaw pivots about the body to a closed position against the fixed plier jaw. The closed plier jaws include an opening that surrounds and engages a driven section of the adaptor. The driven section includes an elongated cross-section to form a long torque arm within the closed jaw opening. A flange at each end of the driven section holds the adaptor in an axial direction. A universal socket may be attached to the driven end of the adaptor to provide a wrench suitable for many fastener shapes.
