I had a set of snap tools that looked like the letter P with the bottom of the loop wrapped around the upright. The lower part of the P was filed flat. Was far faster to use than the snap guns as the tension was so easy to change by how far down the loop was pressed before it was released and allowed to snap back. Anybody know where to buy these things anymore? I know I could get some spring steel and make my own, but I'm getting lazy in my old age.
