Effect
The Knife Through Card trick creates a dramatic visual moment. A spectator selects a card, which is then lost in the deck. The deck is secured with a rubber band and placed inside a bag. The spectator holds a knife, and the magician slams the bag onto the blade. When the bag is removed, the spectator's chosen card appears impaled on the knife. The effect is striking and leaves a strong impression.
Full Details
The Knife Through Card is one of many routines possible with David Stone's "Tool" gimmick. The gimmick consists of two props—one for red decks and one for blue decks—housed in tuck cases. The trick relies on the gimmick's design to conceal the method while allowing for a clean presentation. The effect is self-contained, meaning no additional setup is needed beyond the gimmick and a standard deck of cards.
Who Should Consider the Trick
This trick suits magicians who want a visually powerful effect with minimal sleight of hand. It works well for performers who enjoy storytelling or dramatic presentations. Since the gimmick is versatile, magicians who appreciate multi-use props will find value in it. Beginners can perform it with little practice, while experienced magicians can integrate it into more complex routines.
Difficulty
The Knife Through Card is not difficult to perform. The gimmick handles most of the work, making it accessible to beginners. The main challenge is presentation—selling the moment of impact for maximum effect. No advanced sleight of hand is required, but smooth handling and confidence improve the performance.
