Finger Chopper (aka Finger Guillotine)

A miniature “guillotine” is introduced. Show how the chopper perfectly cuts  a small carrot, sausage or cigarette may fit perfectly. Now ask a spectator to introduce his/her forefinger. Bring the blade down quickly and, of course, their finger will be unharmed! It will look as if the blade has passed through their finger. A cigarette (or any similar item) may also be placed in the smaller bottom hole during the finger chop. Amazingly the cigarette is cut but the finger is not!
