ABSTRACT:
A hand tool includes an electrically-conductive work engaging portion. The electrically-conductive work engaging portion is connected in series with a fuse which, in turn, is connected in series with the tool handle. Small electrical charges are allowed to flow through the tool and dissipated through a charge dissipation system. If a large charge passes through the tool, the fuse blows, thus preventing injury to the tool user.
