Abstract
An electrically heated toolbox for heating hand tools that have been stored or used in a cold environment. The toolbox is a multiple drawer container which has installed therein heating sheets integrally connected to an outside electrical power source, alternating current (AC) or direct current (DC). The heating sheets warm the hand tools by radiated heat or direct heat when the heating sheets are connected to the outside power source. A desired temperature may be obtained by using the rheostat temperature setting device. The toolbox may be connected to a standard AC plug connection, a DC vehicle battery or, if desired, a cigarette lighter outlet of a vehicle.
