For all you jewelry makers and crafters out there, this steel ring mandrel is an absolute essential for your workshop! This solid steel tool is tapered from 25mm down to 12mm, making it perfect for shaping, forming, and resizing all kinds of rings and jewelry pieces. Whether you're working on ring shanks that got bent out of shape or creating new pieces from scratch, this mandrel gives you that professional foundation to work against. It's heavy enough to stay put while you're hammering or forming metal, but the smooth surface won't damage your work. Super handy for both beginners learning the craft and experienced jewelers who need reliable tools. You can use it with various metals - silver, gold, copper, you name it. The tapered design means you can work on different ring sizes without switching tools. Just remember, this one doesn't have the UK ring sizes marked, so it's purely for shaping and forming. If you're serious about jewelry making or just want to fix those bent rings, this mandrel is definitely worth having in your toolkit!
