question

[fenwick99]

In the TAO there is alist of tools from JKD. One of the techniques is called a "quarterswing."
I have never heard of the quarterswing being taught as part of jkd.
What is it?
I have always assumed it was like a short-range hammerfist used
like a boxr's inside hook.

sound like the same thing as in panantuken, attacking the hand.
