If you are going to remove the fingers from boards, the easiest method I have found is to simply take either a 2x4 or 2x6 piece of strong wood, cut a slot across it and then feed the boards finger end into the slot, while sitting or anchoring the other end of the board, and pushing on it in one direction until it snaps cleanly off. In this way you are not creating particulates by sawing that could be breathed in and cause health issues later down the road. It's fast, and easy.
In some cases, depending on who it is purchasing the boards, it might be more profitable retaining the fingers with the boards, or not. There is evidence on either side.
