My husband, after many hints, purchased the Kam Snap Professional press for me for Christmas. I make handbags and the Kam press has made the process of adding double cap rivets so easy. With little effort the rivets are installed and look professionally applied. I watched a youtube handbag making video about rivet presses and the woman said, "if you purchase anything to make your experience easier, make it a Kam snap press" and she was absolutely right.
