So the title pretty much sums it up. I would be grabbing a Naniwa stone because I am very pleased with my current ones. I was wondering though, would a 220 or a 400 be more useful? I currently need one because I have a razor that is so close to a full wedge (2/3's of it is hone wear) that I just wanna go the whole way, but it swarf's up the 1k so fast it takes for ever. Obviously for this I'd want the 220, but down the road, which would be more useful?
Thanks!
