One of the guys in the Lowers was a weapons expert and pulled out a variety of nice knives all through the movie. I saw a SOG model (although I couldn't ID it as it was whipping at another guy's head) and a Hibben Rambo III. There were lots of others, and I think I saw a Ken Onion Whisper. I can't be certain of it though, and there were lots of others I couldn't identify, but it was a good movie and well worth watching beyond all the knife porn!
