The K.M. move was devised by Tony Kardyro and Ed Marlo, and jointly published in The K.M. Move, 1962, p. 2. It has its roots in the fingertip version of the slip cut. More directly, it has a predecessor in a move of Charles Jordan's in “Sympathetic Sympathy” from Four Full Hands of Down to the Minute Magical Effects, 1922, p. 27 of the 1947 edition. Jordan would hold two packs of cards, and then pull the top card of the upper pack down to the top of the lower pack during a wrist kill. The K.M. Move uses the identical actions, but with two cards instead of two decks.
