Knife through Arm | Premium Magic Griffin However once you have itEffect: The magician shows a large dangerous looking dagger. He holds it in his right hand and strikes against his left hand. He moves it against his left arm as if cutting a vegetable. Then suddenly the blade penetrates the hand and blood comes out of the arm. This is a very disturbing illusion and a sure shock to the spectators. (Blood not included)
