More common is one 4 jaw chuck or no tooling at all...but every once in a while a seller includes 3 and sometimes 4 chucks with their machine... and wondering if any chucks beyond 2 are duplicates.... or there did there exist a third or fourth unique four jaw chuck for these grinders that escaped my notice somehow ?
For example...Optima Drill Sharpener Grinder Universal Model B1611 w/cabinet and acc FREE SHIP | eBay
4 chucks.....are they 2 duplicates, or 4 unique chucks.... or 3 unique and 1 duplicate.... or ?
