This is a Jewelers multi tool that Jewlery artist George Weaver designed to help speed up his work flow. It features a sheet metal thickness gauge, a circle divider for marking equal divisions around a ring, and a ring blank ruler for sizes 1 through 13 including half sizes. Quarter sizes can be easily estimated.
This tool allows you to cut fairly accurate ring blank lengths in 12 gauge to 18 gauge metals with a little nudging on your part. You have to account for blade kerf and the such. Made from 2mm thick acrylic.
