A card is selected by a member of the audience, and then replaced in the pack.
While the spectator shuffles the deck, the magician removes his tie, announcing he will use it as a sword to try and stab the chosen card.
He retrieves the deck and fans the cards.
The magician whips his tie over the fan and very clearly, a card is seen to be stabbed at the end of the tie....it's the chosen card!
The spectator himself removes the card and everything may be handed out for complete examination.
An unbelievable effect!
