The Zarrow Shuffle is a great false shuffle that preserves the order of the whole deck. There are several versions of the Zarrow Shuffle. This one begins with a slip cut.
It will take a good amount of practice to be able to do this shuffle well. There is a big difference between an average Zarrow shuffle and a great Zarrow shuffle.
Invented by magician Herb Zarrow and first published in The New Phoenix No. 346, July 1957, page 210, as Full Deck Control.
