The tip of this tool is ground to 4 sharp edges, to enable you to grip the soft aluminum slug at the inside tip of the cap and unscrew it. This tool comes in VERY handy when taking apart parker pencil caps on Vacs, 51s, and others that have aluminum or brass slugs in the top of the cap, usually on top of a brass cap insert. The sharp corners of the tip of this tool grab onto the hole in the underside of that slug (shown in the photos) and are a great aid in removing the clip screw (jewel) and exposing the slot under the jewel so you can get at the bushing that holds the clip on. You will still need a Gooey Cube or some non-skid padding on the jewel side to give you a little friction there to help turn the jewel out. Dale found a rusty version of this in a load of surplus tools from the Janesville plant. He kept it in his work bench for a year or so before he figured out what it was for. It's been an indispensable tool ever since, so we had it manufactured so we can release this to the pen community.
