The swage is used by Blacksmiths and Tinsmiths to form round stock for tenons etc. No more searching for the heavy expensive swage blocks, or having to manhandle one!Artist Blacksmiths sometimes require a tool that will allow metal to be formed in ways that an anvil or traditional industrial swage block will not allow. We developed swage blocks that are individual and easy to handle that can be held in a vise. These are very useful tools.
