ABSTRACT:
A device for detecting the presence of an electric current in a conductor having a elongate hollow tubular body defining a handle, an electrically conductive blade having a sharpened edge attached to and extending from one end of the handle, an electric lamp visibly housed within the handle and electrically connected to the blade and a ground wire electrically connected to the lamp and including a clamp for secured attachment to a ground. The sharpened edge of the blade is specifically structured and disposed for cutting through the insulation of a wire conductor for conductive contact therewith whereupon the presence of an electric current through the conductor will illuminate the lamp in the handle of the device.
