Abstract: A hand held tool has a handle of generally rectangular cross section and a bulbous end portion. A shank is embedded in the handle and extends from the end opposite the bulbous portion to terminate in a work engaging tool such as a screwdriver blade. A self-focusing light bulb is carried in a relieved portion of one side of the handle and is electrically connected to a battery also carried in the relieved portion. A retaining member providing a metal strip removably mounts in place on the handle to retain the battery and light bulb in the relieved portion and to provide a smooth closure therefore. A tang on the metal strip engages one end of the battery, and the other end of the strip extends forwardly in slightly spaced relation to the base of the light bulb.
