Hard stone easy to clean. Feels quite fine,I use it for final on low end knives. I think this is ansi 600-bonded(blocks)/loose grit,which is roughly JIS 1000 to 1200,or ansi 800 to 1000 -coated(sandpaper/film).

Great stone cuts very well in the progression of the factory edge pro stones. And with Marks customer service you can’t beat it.
