I just started making key fobs and am wondering what you all use to crimp the hardward closed. I've been using pliers that my dad had - it looks like a monkey wrench (LOL not sure if that's even the right name for the tool!) - and cushioning it with a dish towel. It works okay but just takes a while because I have to go very gently from each side to avoid making dents in the metal. Is there another easier way to do this or a tool that I can buy that has a wide flat press?
