Probably the name of this shuffle card came from the way it was executed. When the cheater performs a shuffle, the cards are in the hand like a fan. That’s about how it happens. From cards of the deck a giant fan is laid out, which is held by two hands, then the fan is divided into two parts, resulting in each hand has one fan. Then the fan of the left hand is folded with the fan of the right hand, and it is depicted as if one fan is folded with the other in a cut, and in fact, the cards are not mixed but are in the position in which the shooting was taken, that is, the top of the deck is moved down. To get the cards to their original position, you need to repeat the motion data with the fan once again.
