okay... Just finished shaving with my freshly honed Bismarck and it worked like awesome from beginning to end! Even did an ATG pas with no issue of dulling. That said, I would like to keep this type of condition going. If stopping on bare leather only now, how many passes should I be doing before shaving next? If I start noticing the edge degrading early, what would my next course of action be? going back to 8k? Try a dozen passes or so on the 13k?
