Knife Thru Bill by Shawn Lee
Borrow a bill and fold it. Take out a blade and pierce through the bill! The blade slids over the bill, and for the audience, the bill was ruined, but when it is shown again, the bill is still intact.
There are many similar tricks, but this product looks more direct, more enjoyable, and more realistic. The blade slids across, and audience will feel distressed to look at it. And the final result gives the audience a greater psychological contrast.
Any type of bill or paper can be used and also be examined before and after performance.
Comes with a gimmick blade (sharp, must be careful) and video instruction.
