Erdnase False Cut
This false cut comes straight from the bible of gambling sleights - Expert at the Card Table by S.W. Erdnase. A good reason to be adept at this sleight is if you are playing with another crooked gambler as a team and he is about to deal. If you can maneuver yourself into a position to be the cut man (to the right of your partner) you can perform this false cut and pass him back the deck in perfect order.
