This is a great effect that you can do with any borrowed bill! A utility knife and a small square of paper are displayed by the magician. A bill is borrowed from a spectator and folded in half vertically. The small piece of paper is then folded over the center of the bill. The knife is now openly pierced through the center of the bill and the paper. It is then slit down the middle of the bill and paper. The paper is clearly shown cut by the blade…but the bill is completely unharmed! A great pocket effect that you can carry and perform at a moment's notice.
