I bought this one back in the latter half of the 70's when I was a young and impressionable teenagers who bought everything with an edge on it. I remember I was told it was a Vietnam-issue knife. But since Camillus produced knives for both the civilian and the military marked, I'm not so sure. So I just have to ask the experts here whether or not this is a real military issue ka-bar from the Vietnam era or just something for the civilian marked. Total length of the knife: 12 in. Blade length 7 in.
