Abstract: A hand held drill leverage unit for supporting, positioning, and leveraging a drill. The leverage unit has a main lever arm pivotally supported by a fulcrum unit. A drill end of the lever arm supports the drill, while an opposing, longer, handle end of the lever allows manipulation of the lever arm to control the position of, and to leverage, the drill. A user typically grasps the drill handle in one hand, the handle end of the lever arm in the other. Pulling the handle end away from the workpiece forces a leg or foot member of the fulcrum unit against a rear side of the workpiece or of another support member, making the fulcrum unit substantially stationary relative to the workpiece, so that further pulling of the handle end forces the drill end toward the work piece. As the preferred leverage unit need not be fastened or fixed to the workpiece or other support member, the user may quickly and easily move the drill and leverage unit to multiple drilling locations.

Abstract: An improvement to the standard manually powered cold knife used to remove vehicle windows is disclosed. The standard cold knife has a main handle, which is generally cylindrical. A blade is fixedly attached to the base of the handle, and is shaped to reach beneath vehicle window glass. A pull handle is attached at or near the base of the main handle of the standard cold knife. The invention is an additional stiff pull handle attached at or near the top of the main handle. The length of the additional pull handle is designed to roughly match that of the first pull handle, and the grip is designed so that the grip on the first pull handle roughly fits into it, allowing them to be comfortably gripped together.
