Thread: Nagura Progression and a scratched Ozuku

That would bother me too, but the scratches probably will have no affect on a razor. If they really bother you, you would have to lap the surface of the stone to refresh the surface a little.

Have you bevelled/smoothed the edges of your tomo nagura? It was probably that stone during slurrying that caused the scratches. Even if it is softer, a sharp edge dragged along the smooth surface of the stone would likely cause a bit of a scratch.
