Finish swivel

[8cork]

While driving through to both arms straight, where does finish swivel prep begin, and is it different for hitters vs swingers? Is it accomplished with a counterclockwise curl of the left hand after follow-through?

Thanks

For me, the finish swivel prep begins with the awareness of a lagging clubhead and a bent right wrist through impact. Once your right arm can't go any further down and out, your right forearm makes a counterclockwise twist while maintaining the bent right wrist and the club is swiveled back to plane.
