Description
You place a borrowed banknote on a piece of paper of the same size. Fold it up and push the knife through so that the tip is visible on the other side. With a quick movement – and the sound of paper being cut – you guide the knife across. Then you can return the whole banknote to its rightful owner.
The knife is 23 cm long with a 1.5 cm diameter handle and a 1 mm thick blade.
