Input...
Conwict--"Input" could be something on the order of, "That is the stupidest idea I've ever seen--would never, never carry that knife or anything like it." Input doesn't have to be advice on design, or positive comments. And, an Army Ranger, while trained and skilled in combat survival, may or may not know something about knife making.
Kind of like the British, "Purveyors to the Crown" means we sold some to Buckingham Palace, once--doesn't say whether or not the Queen used or liked the item.
I agree, the cordwrap, if you get the knife into something icky (an ordinary occurence, with a general-purpose blade!) will stink and be hard to clean, short of just replacing it.
And, FWIW, I too dislike the idea of a serrated blade back.
