Rivet Setters - are used to set copper rivets for joining leather pieces together. They may be a three piece set that sets the burr over the shank, peens the burr after clipping the shank to length, and then domes the head of the rivet. Rivet setters may also be a single tool that sets the burr and peens it after clipping to length.
