This is a very old and historic tool, from the period 1500 to 1600. It was a multi purpose tool used with Wheel Lock Pistols. It is complete, amazingly, even the ” pick” tool is still attached by a forged link. This tool performed many tasks in conjunction with the use of a Wheel Lock pistol. They are simply never seen, and an ultimate scarcity, rarer than the pistol itself. So. if you have a Wheel Lock in your collection, this makes an incredible companion piece.
