I'm Sorry but when I think of "knife combat" I instantly think of that scene in Saving Private Ryan where that big burly German plunges that combat knife into the American GI's throat.
Are you referring to the knock down, drag out, on the floor, on the second floor, fight where the third soldier was writhing around after being shot in the throat? If so, the German didn't "plunge" it..he slowly pushed it into the soldiers abdomen...not his throat.
The baton the other gentleman asked about is normally called an ASP.
