Knife Fighting

[Vuk]

Hey all, I am looking to get a knife fighting expert to come down to my TKD club and give a seminar some time. I was wondering, what are some really good knife fighting systems? From what I have seen, Eskrima and different styles of Silat look like they have some really good stuff for knife fighting, but I was wondering if you knew of any other that I could check into. (or if you could give an opinion on which would better be suited to modern knife defense)
Knife fighting seems to be one of those things that gets overlooked in most popular MAs in the US, so I was thinking of giving the club members (and myself) a rounder education on it.
