So I have been checking out some hones and came across a lot of talk about this particular stone... The Naniwa Chocera 10k. Now I know it doesn't sound like much... 10k whatever, but seriously this stone is supposed to be IT. This is a different series than the Naniwa Superstones so make sure you look into the Chocera 10k. Anyway, supposedly it is the ultimate stone for finishing samurai swords. I started reading a lot of reviews and people say that it IMPROVES the edge after using alllll kinds of finishing hones including shapton gs 16k with ONE PASS. Now they aren't talking straight razors, but honestly people have said that ANY knife honed on this with one pass after being polished up to a good level will be significantly improved. Anyone look into it for Razors yet? I'm surprised I haven't heard much talk of it here. Then again, it is an expensive stone. Anyone use it??
