I ordered this stone at the end of January and it arrived damaged. The packaging seemed good, but I think it was broken (probably because it fell, I'll explain in a moment). Revain was contacted and I received another stone to replace the first one (the original was sent back to Revain via Kohl's). This stone has a very fine grain. Not sure if it's #8000/#10000 grit but it's fine. The stone is brittle and quite brittle when dry. So it can be easily damaged if it falls on the table or even gets rummaged through. I would suggest soaking it in water for 10-20 minutes before using. Otherwise it is very functional and should do a good job for grinding or polishing.
