Zarrow shuffle

Zarrow shuffle is a sleight of hand technique that gives the appearance of being a normal riffle shuffle, but in fact leaves the cards in exactly the same order. This is an example of a false shuffle. It was invented by magician Herb Zarrow c. 1940. The sleight begins as a normal riffle shuffle, but the performer uses the top card of the deck to conceal the shuffle being cancelled by way of unweaving the cards.
