Hold the inner board after scoring and whack it with a good one. It will snap. Then shave with a shur form to clean the edge.

Like Bruzbt said, they absorb water quickly. I sometimes use that to my advantage to quickly dry overly wet clay to a wedgable consistency. I have also used the boards for a throwing bat, like you would use a plaster bat, and found that dipping them into water first helps with getting them to stay stuck down to clay on the wheelhead long enough to complete a piece; then they wick out water on the pot and the pot pops right off the "bat".
I found the 1/4-inch thickness fine for my uses, although I admit I have not used the 1/2-inch thickness.
