I tested this one quite some time. And i really like it
I am always skeptical to coarse Japanese Natural stones
But this one i do really like and use a lot now. It is splash and go so don't need any soaking
It acts like my JNS 300 synthetic, but bit softer. Makes super uniform finish without any deep scratches
It dose actually sharpen and can remove chips witch is super Rare for any Natural stones
So not much to say then i love this stone :D
Grit Rage is from 300 - 800 if compered to Synthetics
It can be used on all Sides !
Picture is just a sample !
Approx. size: 220mm 70mm 58mm
