Who wants to grind very blunt knife, but should use first additional grinding stones that have a coarser. For a super fine-tuning could use a stone with 4000 grit also, which I personally find for everyday use as exaggerated.
This whetstone is delivered with a bamboo tray which offers a good slip resistance while working. I use the stone for several weeks now and do not regret the purchase.
Conclusion: A good whetstone for (even better quality) diameter in normal domestic use. Good value for money.
