A tile saw with a diamond blade and continuous water bath should cut a Norton easily. If these saws can cut ceramic or porcelain tile, concrete pavers, and real stone tile (which they can), slicing a Norton should be effortless for that type of machine. After all, the novaculite and coticule hones are cut with this type of saw. Norton may also use them to bring their stones to finished dimension. You may be able to cut them with a bandsaw, but I suspect the blade will be scrap before you're done and then you have all that abrasive dust to clean out of the machine (and your nose).
good luck, Bruce
