Good postings, but you guys missed a few, and I have a small anecdote.
The bad guy in the beginning uses a Spyderco Police to "off" the prostitute.
When they were selecting the knives(amazing scene, for me!) a Joe Kious subhilt was also presented.  I think Coyote took the Randall, and Hermes took the Kious, which Coyote paid for.
I was watching the movie in my knife shop, and called Kious to order some of the "Exposure Subhilt".  This was in 1995, and he was making fixed blades then.  We sold them, in ATS-34 and assorted wood handles, for $750.00.  I have no idea what they are worth now.  The workmanship was exceptional.
Exposure as a movie, is kind of , well, marginal.  BUT, the knife stuff was very exciting.  
Lots of movies have some knife work in them, 8 mm, Gladiator, Gangs of New York, Road House, The Crow, which no one mentioned yet, had the great scene towards the beginning when Tin and Eric go at it, here's a trivia question, and I'll make it easy.  What was the brand of knife that Tin Tin seemed to prefer, extra points for the model?  no cheating!
Just having knives in and of themselves, does not a knife movie make.  Like The Fan, which no one mentioned either.
Have fun, this was an interesting thread!
