There is also a condition know as "Pulling Wood", this ossurs when the shooter lays thier finger flat along the side of the wood disabling every finger joint except for the tip. Just try immobilising your whole finger ans see how much movement you get from just the tip, you will also note when you do this there is little feeling or strenght. This condition can be overcome by taping a small piece of dowell to the wood so as the main knuckle at the palm rests on it and keeps all finger joints free of the wood. It really works where this condition is the problem.
