The knife itself is decent but not jaw-dropping--it's basically a hard-use folder. What's nifty about it is the onboard takedown tool. It's kind of like the original 1911/1911A1 where everything you need to completely disassemble it (excluding staked parts) is a part of the pistol itself.
Several knife makers include the tool(s) to disassemble the knife, but this is the first one I've seen that actually stows the tool onboard. That's pretty cool. I don't know if it's $500 cool, but it's still pretty cool.
