Shazb0tI've been watching for well over a year, and this knife comes up every month or 2. The 599 has never once come up, despite constantly being asked for and voted for.
KabaAgreed that the 599 is more desirable.
However, it's an exclusive of theultimateknife.com. I wasn't exactly sure how that exclusivity worked, until I saw a youtube video where Vlad from ultimateknife explained how he actually got the design drawings from Fox, redesigned it, made it smaller, and sent designs back to Fox to manufacture as the 599.
