Ah, finally something I can relate to...
This is something of a mindset that needs to be addressed by each wearer IMO. I agree with Dale S. on his points.

My personal feelings;
Knives are a tool, what you do with it is up to you. I carry a spring assisted lock blade pocket knife every day. I use it multiple times a day and do feel naked with out it in place. It clips to the pocket so it is visible, is under the CO law's 3.5" requirement and is razor sharp. If I were wearing a kilt with hose, I would have to carry it in my sporran. I do consider it a close range weapon should I have a need for it. In fact, a knife attack is the only thing I really fear (other than shotgun). I too am trained in self defense (Krav Maga) and have other higher force tools.
I have a personal belief that any knife is a weapon and should be looked at as one. If it's visible in public - as should be, criminals (Coyotes), mindless sheep and general public sheep will most likely see it the same way. I treat every day as a possible situation day, which is not a bad thing these days. So, decorations that give the illusion of real tools are not wise to me. When I carry my Sgain Dubh, it is a weapon and will be treated as such. I believe a person needs to be aware of this mentally and be OK with that feeling. Such as someone carrying for the first time at level 0 with a concealed pistol. It is the same thing in my mind! I have seen training videos of people dying in less than 3 minutes from a 3" knife stab in the neck. But I digress, sorry...
Bottom line, if it's legal in your state, town ect, I say carry it for the tool it is and be aware of it and people around you. MacMillan's son couldn't have said it much better. And if you plan to partake of some good Whiskey, leave it at home or locked in your friend's car like any other weapon. Judges, alcohol and weapons don't mix.
