One politically-incorrect observation about the political correctness of certain knives. Let's say you actually have to defend yourself (legitimately, legally) against an attacker, and actually use your knife to do so. After the fact, the bad guy and/or his next of kin sues you for an unjustified assault and battery (or wrongful death). You go to court, and your knife is introduced as an exhibit.
However "friendly-looking" and non-weapon-like your knife may appear, what do you think is going to be the likely reaction when the jury is informed that the name of the designer or endorser etched onto the blade is the name of a famous fighting school or fighting instructor? Especially when many weapons ordinances have "either/or" language to describe illegal knives, along the lines of "blade longer than X inches; OR designed for use as a weapon." Under some laws, even a knife that was under the legal maximum blade length could cause trouble if someone recognizes the name as a "tactical" designer or instructor.
Just a question to ask yourself. I've got to say, I'm impressed by many designs that bear the names of famous combat instructors--and you know who you are. I've just wondered whether the advantages of that might turn counterproductive.
