Sleight of hand, also known as prestidigitation ("quick fingers") or léger de main (from the French for "lightness of hand"), is the set of techniques used by a magician (or card sharp) to manipulate objects such as cards and coins secretly.
Sleight of hand is not a separate branch of magic, but rather one of the means used by a magician to produce an effect. It can be contrasted with the flourish, where the magician intentionally displays skills, such as the ability to cut cards one handed, which is akin to juggling.
Advanced sleight of hand requires months or years of practice before it can be performed proficiently in front of spectators. Sleight of hand is mostly employed in close-up magic, but it can also be used in stage magic. There are hundreds of different sleights at the performer's disposal, but they can generally be classified into groups: switches, changes, etc.
There are several stories about magicians using sleight of hand in real life, such as the one about American illusionist David Copperfield using sleight-of-hand to fool a mugger into thinking he had no wallet in his pockets.
