Chalk ball was supposed to be for chalking up, I was able to hang and chalk both hands while working it but couldn't manage that on the link. It seemed a good odea at the time but why I didn't chalk thighs for a quick slap or simply use a chalk bag I have no idea.
At first I thought it was drying the hole, then you don't use the hole. One for the "devious tricks and tactics" thread

Coops good luck with finding something that can work with your wrist.
