Product Review

Heavy duty wire working tool , made of hardened tool steel. Can use for basic ring sizing. Markings show sizes 1 up to 15, with unmarked lines at quarter and half size intervals. Unlike plastic ring sizers, you can use this solid metal mandrel for hammering metal. Form rings directly on mandrel! You can re-round rings that have become bent with wear by slowly forcing them down the mandrel until desired shape is achieved.
