It's extremely fine. It would take hours to reset a bevel. I can take 100-200 passes on it when wet and it polishes the edge, but removes very little metal. After I strop with CrO2 you barely see any scratches at all. It's 80% mirror finish with a few interspersed scratches at 30X magniifcation. It shines mirror like to the naked eye before stropping.
