I have been wondering this too, specifically regarding Kizlyar Supreme. Knifeworks.com has had many of them on closeout for a while, some with very attractive prices. Did a bunch of searching a while back, and could find no real reviews of them anywhere. However, I seem to remember that there are two companies - Kizlyar, and Kizlyar Supreme, and that they were two distinctly different companies.
Hso, would you have any more info on that?
