Crimps are a great tool for magicians to use. By using them, you can eliminate some of the trick
slight of hand moves used to control cards, and you can make mixing the deck be much more realistic.
The idea of the breather crimp is nice, but I don't like having the feeling of it in my deck. You
don't have to use it if you don't want though, you can just use a regular crimp and be fine with
that.
