Abstract
A multi-tool with an assembly of tool instruments particularly useful for the field maintenance of chain saws. The multi-tool includes a hollow handle with a spark plug socket connected at one and a plurality of tool instruments pivotally connected at the end opposite the spark plug socket. The tool instruments include a raker gauge, small tooth file, large tooth file, small screw driver, large screw driver, air filter brush and serrated knife. The tools pivot about the handle end into the hollow handle. Included with the tool is a sliver tweezer which is insertable into an aperture formed within the multi-tool handle. The spark plug socket is pivoted about one end of the multi-tool handle and locked in place in a keyed-portion of the handle, thereby providing a tool acting as a socket wrench capable of applying substantial torque to a work piece, e.g., spark plug.
