Clean Cut Knife Routine by Mark Lee
The magician displays a pocket knife to the audience. He causes the knife to change colour several times before offering and explanation, he explains that he is using two knives and is switching them. The magician now shows a second knife of a different colour to the first and proceeds to cause the knives to transpose in a magical manner. Finally he changes one knife to become a different colour on both sides and the second knife takes on the image of a card box! Everything can be examined with nothing added or taken away. Instantly re-set. Easy to do...
