I was reading another thread which got me thinking. So I did a little research. Goshman is often credited with a move called the Goshman pinch in reality it was the Tenkai backclip, which has also been called the
Tenkai back palm. Goshman did not create it, he did not claim to create it. It seems he contributed work to Bobo's Coin magic, and Bobo did realize it was not Goshmans move.
This is however a coin move. So while it can be successfully argued that there is indeed a Tenkai backpalm I too would need to see the effect performed to believe it works as described on another thread on this message board.
The above information I found in a conversation between Harvey Rosenthal, Mike Gallo, Jon Rachanbacher. You can click on the link to read up.
