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
Very very consistent stone almost like synthetics have no inclusions or any lines ! Color is also super uniform and same on all stones
Grit Rage is from 1000 - 3000 if compered to Synthetics good Aoto replacement !
It can be used on all Sides !
Picture is just a sample ! Huge stone
Approx. size: 240mm 75mm 60mm
