Question for Trained Knife Fighters

[FortTom]

I have no idea what a "trained knife fighter" is - that the old school "gentleman's duel" style stiletto boot knife street fight guys used to have over "broads" in the 50's ?

I guess I would define it as someone who has a lot, to extensive training in the handling of a knife for someone caught in the unenviable position of having to defend themselves with a knife, as opposed to someone in the street fighting over broads in the 50's. Someone who might make use of those "blue" knives to train themselves in the discipline, that you take pictures of, to post on the forum, that come with the $500 "fighting" knives, that make knife " training " much smarter than using a sharpened blade?? Something like that might make you a trained knife figher?
