The Rivet Setter is a very simple tool for setting snug and attractive Copper Rivets. Using a medium weight hammer, it will seat the Burr (washer), pulling your fabrics tightly together. Once you've cut the excess rivet shank down (just proud of the Burr), the Setter will also peen over the cut-end permanently holding the pieces together (think of classic Levi blue jeans). It's a very strong and attractive way to reinforce high stress areas. Use our Revolving Hole Punch (link) to create a snug hole for the rivet shank. Detailed instructions will come with the kit. Each Rivet Setter Kit comes with 25 Copper Rivets to get you started. It's all a very satisfying kind of work.
