Best spec-ops-dark-ninja-anti-terrorist folder out there is quite easily the Böker Kalashnikov 101. That thing is so wrong, it goes all the way around to feeling right again. I swear that blade shouldn't feel as good as it does in hand. It always brings a grin to my face holding that thing.
And you know what's best of all? It's affordable but you can tell your non knife people friends it cost 500 bucks because it was designed by Mikhail Kalashnikov, which of course it wasn't. In fact I doubt Kalashnikov ever laid eyes on the thing but hey, they don't know that right. And that glass breaker on the end? That's no glass breaker that's a frickin' skullcrusher. because that's how Russian special forces roll baby...
Okay j/k, but that thing really is my no1 guilty pleasure
