This is basically a billet knife on steroids with a very sensible addition to eliminate the need for the assistant! Unlike the original, you can begin with the knife on the table before you start!
You can still perform the standard routines with this billet knife but you cannot do the following routine with other versions on the market!
A paper knife and three envelopes each with the word “Performer”, “Spectator”, and “Audiences” written on it are shown. The envelopes are then handed to a spectator to hold and he may examine these envelopes to assure they are sealed and have never been tampered with. The performer then calls out three objects in the room and asks the spectator to choose one for himself, one for the performer, and one to be given to the audiences. The choices are always up to the spectator and he may change his mind before he commit to the selections. Once the prediction is ready to be revealed, the performer point out that he actually knew, way in advance, what the outcome of this experiment would be. To prove it, the performer takes each envelope and slits it open with a paper knife, handing it back to the spectator to remove the contents. Inside each envelope, he finds a prediction which matches exactly where each of the object is now located!
This uniquely and expertly engineered billet knife is made entirely of the finest selected teak with a measurement of nearly 9” long by a master craftsman.
