#5 Dark Tomae is well suited for knives as it is a fast cutting and fine enought for sushi but not for shaving. I have honed a razor with this stone and it would be best used as a pre-finisher, but for knives as the last stone. With the use of the tomonagura (included) it is very fast and makes bevel work easier. The stone is attached to a painted wooden base. I am not sure which mine this stone came from.
