Cards as Weapons is a book written by Ricky Jay. It has been referred to in the New Yorker as "...diverting and richly informative."[1]. It has been a notoriously out-of-print book; available copies are often listed for hundreds of dollars. Its rarity and the card-throwing technique described in the book figured in an episode of Jonathan Creek, "The Three Gamblers."
The book was also mentioned by author Ricky Jay on 20th episode of Mythbusters, when asked whether he had heard about the "Deadly Playing Cards" myth.
