Hi there!
I just got yesterday a Naniwa 2000 for bevel setting on some old razors I got. There's one thing that keeps me worried.
The stone seems very soft and as soon as 7-10 laps I can see thick black scratches on the hone (I pressume from the razor itself). Are those normal? Do I have to clean them in order to get better results of the hone or can I leave them there?
Thanks!
