I love these stones. I resurfaced my WoA today so I'll give it another shot on a razor. From the edge it put on my pocket knife in sure it will do fine. It made a pretty noticeable change to the edge within 10 laps, and I remembered it being slow. To be fair, I didn't REALLY give it the old college try, I wrote it off pretty quickly. I think since I finished it down to 1k it should be much better. I didn't remember it having tiny pores either. They're similar to the ones that my vintage blue la lune(more of a silver/black) has but they're much smaller.
