As for cutting into that stone, I would never do it - Too many lines in it and if you rubbed that on your base stone, it would scratch it very easily. To get rid of the lines in the hypothetical nagura, you would end up wasting at least half of the stone, and end up with very small nagura. Not that they wouldn't work, but they certainly wouldn't be worth a lot.
