+ Really really liked the non-slip rubber base and the good size of the stone.
I recommend rather for example those manufactured in Germany unilateral Missarka Ultra Red. The attached much harder wearing much faster (even faster than the 2000 side of this stone) and yet achieved a noticeable increase in sharpness as the 5000 side of this stone. He is also to be a bit cheaper and consumption watered only shorter.
Or if you absolutely soft bound Waterstones preferred the Naniwa Super Stone series, which are pretty much the best artificial water stones in the market and much better than this one, but are also more expensive ~ 10-20.
