ABSTRACT:
A device for holding and aiding in the sharpening of welding rods includes an elongated handle member defining an axial elongated cavity into which a workpiece can be inserted and housed. The exterior of the handle member can be firmly grasped so that a user can manually bring the exposed end of the workpiece into and out of proximity with a grinding tool to sharpen the end of the workpiece to a desired degree. A plurality of threaded apertures communicating with and transverse to the cavity are defined in the handle a predetermined axial distance from one another. At least one thumb-screw having a depending nib is threadably engaged with a preselected one of the apertures, thereby extending the nib into the cavity to obstruct it. When the elongated workpiece is inserted into the cavity, one end of the workpiece abuts the nib to determine the axial position the workpiece in the cavity. The rib is arcuately shaped to reduce the surface area of the nib contacting the end of the rod, thereby permitting the elongated workpiece to freely axially spin within the cavity. The preselected one of the apertures into which the thumb-screw is engaged may be selected so that an end of the workpiece extends a desired length beyond the distal end of the handle member. When the exposed end of the workpiece is brought into oblique contact with the rotating abrasive wheel of a grinding tool, a tapered point may be easily formed on the end of the workpiece.
