Twisting the aces(original name of the variation)

[swamy]

The twisting move used in "TRICK KARDS" by Nick Trost(The Card Magic of Nick Trost) has been used in many effects.

The question is :
a. What is the name of the effect in which this twisting move was being first used.
b. In which book the original effect can be found.

[swamy]

Does the twisting moves in the effect "Think Touch and Turn" inspired the twisting moves used in the effect "Trick Kards" by Nick Trost or in the effect "Trabucco's twist by Vic Trabucco ?

[Ryan Matney]

The twsiting flourish/move was first published by Vernon in one of the Inner card Secrets books in the first write-up of Vernon's original "Twisting the Aces."

It was used not just as a flourish but to position the cards into the unnatural pinch-grip that was used in the Elmsley count.

[Max Maven]

The Pinch Grip is a perfectly natural way to hold cards.

[Ryan Matney]

But is it a natural way to count or display cards? I prefer the original Elmsley handling, but being of the Card College generation that is the way I first learned it.

It may be natural to hold the packet in pinch grip but to count with both hands in pinch grip has always looked more like a mix to me.
