This is a handy tool for removing your K98 stock. this tool fits the stock cross bolt nut (disc with little holes) on most Mauser rifles including the K98, G98, G43, G33/40 (pictured), Turkish Mausers, Russian Moisin Nagants, and conceivably any Mauser with this style stock attachment system. It is recommended that the little holes are cleaned out first to ensure the posts on this tool go as deep as possible for the best possible grip. The tool is made of steel with hardened steel posts and is coated in black oxide. Not mass produced overseas, these were made here, locally. Put away your needle nose pliers; there is a real tool for that now.
