I recently got a new Oozuku Assagi from Maksim at JapaneseNaturalStones. I've used it a few times in conjunction with my new nagura. I've really gotten great edges. Of course, in true HAD fashion, the stone you have is never good enough. Thus, I received today my second Oozuku. This one comes from Morihei in Tokyo. It is a Oozuku Suita (no su). I haven't tried it out yet, but thought I'd share a bit of stone pr0n with all of the rock hounds...
