Another hard gray Ozuku tomae. This stone is perfect for razors and I have tested it with a Gold Dollar 66 and a Friodur. A lot of fellows uses these hard Ozuku for the final polish, and the tomo nagura that comes with this stone is geared for that method.
The top surface does have some disturbed areas where bias grain reaches the surface. The stone is so hard that the matrix holds the surface structure, so no loose particles come loose. It really is a finisher and not a destroyer.
