Not sold, but ... our house burned and I lost every knife I owned except the one in my pocket. The one that hurt the most was a Kuzan Oda tanto. When I decided I'd try to replace it I found out that he had moved to Japan and only makes high-quality katanas now. Fantastic blade with an honest to goodness haemon, minimized tsuba so it carried flat and close to the body, and some kind of rubber-like handle material that was grippy even with blood on it. I used it occasionally and carried it often for about 4 years, and although it's hard to believe I never had to so much as touch the edge, it was still razor sharp when it burned up. (To be fair, I'm pretty easy on a knife, especially one like that.)
That's probably as close to the mythical Japanese katana as I'll ever get.
