Numata, very hard to find in that size and so clean
I think they have best feedback in about all med grit Natural stones, quite fast and leaves very uniform finish !
It is not to hard and not to soft so about medium hardness, Do not clog and dishes very very slow
have very limited stock of those !
starts about 1k grit ! splash and go, dont need any soaking
Picture is just a sample !
