Seeing those Cold Steel knives in "Plattoon" is a major and annoying distraction (Berengers push-dagger, Dafoes tanto). I don't know if the person choosing the knives for the movie was a total idiot or if they had some sort of product placement deal with Cold Steel.
For a movie that was supposed to be an acurate depiction of the Vietnam war they really blew it on the knives. I think about all the really cool knives they could have used that would have been historically accurate- the common Kabar, Randall, Gereber Mark2, Ek knives, the original and genuine SOG knife, even the black-handled Buck fixed-blades, etc, etc.
This is not a knock against Cold Steel, but seeing those CS knives in "Platoon" would be like seeing guys wearing digital Casio watches and carrying M16's in a movie about the Normandy invasion.
Big fail for Oliver Stone in my book
