Hard, and very fine with fairly fast cutting, just barely self slurrying when used without nagura, a nice fine near mirror finishing stone with a lot of surface to work on. This stone has a few shallow surface cracks that might cause problems later, they are the light lines in the photo of the stone wet, they do not appear to extend through the stone. The price has been adjusted for this issue, a good price for a stone of this quality, for a hard stone it is easy to use. Is nearly flat on it's reverse side.
