The magician displays what appears to be an ordinary single blade pocket knife. The knife is shown to be a sparkle silver color on both sides. With a flick of the wrist, the knife completely changes to a green colored knife! The knife can be made to change back and forth in color, with the magician at any time showing the knife on both sides. Thanks the the paddle move, this incredible magic effect has found its way into the repertoire of many famous magicians.
 
These knives are "squarish," which makes the turnover move very easy to do. Produced by Jim Berg and Derek Kennedy, the quality of these inexpensive knife sets should not be underestimated. They easily compare to other knife sets costing $100 or more. Comes with two knives (silver/silver and silver/green), nice black velvet drawstring pouch, and complete instructions. Price includes shipping in the USA. 0051RUMCOLORCHANGINGK
