Since the 12k Chinese stone is so hard, I was wondering if anyone has used it as a dressing stone to maintain Shaptone stone of finer grits like the 16000(Like a mild lapping stone that leaves a smooth surface). I know some are using it as a slurry stone already, but I thought it might have applications for reducing the need to do more drastic lapping on the Shapton stones. For the price I ordered a couple from Woodcraft, shipping is free right now if anyone else has been considering one.
