Many coin ring makers use costly ring stretcher/reducers that can run from $100 to over $600. I use a Rathburn ring stretcher. It cost me about $20 and I find it to be very useful. I’ll show you how I use it in this video. You can find a link for the Rathburn ring stretcher I use on my recommended tool list linked below.
