This is my understanding of how hookface works. Clubhead COG is not in same plane as the face of the clubhead.

If that is correct then what is happening with the new drivers where COG is forever being moved further back away from clubface?

This was posted by Mathew back in 2006. Get out a few businees cards to make your own Planes and follow along...

"Hookfaced position is when the initial ball flight plane runs directly vertical to the clubface plane and the lie angle plane whilst another plane can be made that is directly vertical to the lie angle plane on a line where the clubface plane intersects the lie angle plane which is also vertical to the clubshaft plane. To the degree that the clubshaft is moved around in a circle from - vertical to the lie angle plane - to towards the lie angle plane itself on the clubshaft plane is the degree it is hookfaced.

Offset is when the initial ball flight plane runs directly vertical to the clubface plane and the lie angle plane whilst another plane can be made that is directly vertical to the lie angle plane on a line where the clubface plane intersects the lie angle plane which is closed to the clubshaft plane. It is most likely that an offset club has a combination of hookface and offset.

Hope that clears things up."
