A magician shows both sides of a pocket knife. He then places the knife in his hand, making a fist. He then pushes the knife out through the fist and the handle has changed color. He repeats the process and the handle returns to its original color. The magician explains two knives are used. He then produces another knife of contrasting color. He says that he was able to fool you by making an invisible switch of the knives. He then holds one knife in the right hand and the other knife in the left. With both arms outstretched and a shake of the hands, both knives change color. Includes instructions. Mild toning, else in very good condition.
