Hades' Improved Finger Chopper by Micky Hades

You ask a spectator to examine both pieces of this two piece, guillotine style finger chopper.  They find the blade to be solid, and the stocks solid as well.  You then take the two pieces back, and place your finger in opening of the "stocks."  You then slide the blade piece through both the stocks and your finger, but your finger remains miraculously intact!  You can then hand both pieces back to the spectator for further examination.
