This stone is pure from front to back and it has a 3D surface that shimmers as you tilt is back and forth, and the stone has a real mellow light gray complexion. Thicker than the average hand held stone, this one gives a sense of authority and the silky smooth surface is silent under the razor. It will come with a slightly softer tomonagura which I used when testing a Henckels Friodur. A stone to brag about.
