There are dozens, here are a few -
Karl Hein - Heinstein Shuffle which is/was on DVD of same name and also in an old issue of Genii.
Hollingworth has one in his book.
Ben Earl has the Grey Shuffle which is on his DVD's Past Midnight. He also has more great false shuffles in Gambit Magazine.
http://www.benjaminearl.com/gambit-magazine/Derek Delgaudio has the Truffle Shuffle which I'm sure you can lean from the Buck twins on demand site. Derek's is about 90% the same as Ben's, just independent invention, no scandal.
Many of these shuffles come from or at least are influenecd by Lennart Green. I'm not sure if Lennart published his shuffle in the end but it isnt on his early DVD's but there are a great variety of false (not riffle) shuffles and cuts on his DVD's.
My favourite is Ben's shuffle and that is what i use. There are loads more than the ones I mentioned though.
