Card Tearing

I've been tearing cards for many years now. I never thought too much about it other than that it takes strong hands and the right technique. I have no doubt in my mind that the new Diesel Crew Card Tearing ebook is going to help me get STRONGER hands and BETTER technique! Jedd has put together a great manual that covers card tearing in it's entirety. If you want to know how to tear a deck of cards, this manual is all you need. If you are already tearing cards, this manual will take you to the next level.
