This is a nice way to bring some additional interest to your card magic set. Because it introduces a familiar "ordinary" item that most people do not associate with a deck of cards -- it is a small knife (very closely styled like the famous and iconic Swiss Army knives). The knife is about 2.5 inches long, similar in size to the keychain Swiss Army knives that mos people have seen. Like its famous cousin, this little knife has not just a blade, but some scissors, tweezers, toothpick and file. (Note: these extra tools are mostly for show and to give the knife more authentic flavor -- they are not really made to function very well.) Two cards are selected from a shuffled deck - one is signed - and both are returned and the deck shuffled by the magician. An empty paper bag and a pocket knife are pulled from the magician's pocket before the deck is tossed inside. The magician shakes the bag to mix the cards and make the finding of the chosen card even more impossible. The knife is opened and stabbed into and through the bag. The magician states that both cards will be on the knife right before he violently rips the knife from the bag and a single card is impaled on the end of the blade. It is the signed card. The magician looks confidant as the crowd wonders why the second card was not on the blade. The magician then turns over the knife to show the second card is printed onto the knife handle bringing the effect to a satisfying conclusion. Everything needed is included! The Special knife, enough paper bags to get you started and the special something that helps with the card stab!
