I don't carry a gun, but I have a knife on me at all times unless I am somewhere it is forbidden by law. I also keep knives of varying length in case I am going somewhere my normal EDC would be illegal to carry such as LA or SF.
I actually have, right this second, at least a dozen knives within arms reach. That's not counting the one in my pocket. Of course that is because I've been doing some sharpening the past few days. Actually, I just counted 15 knives that I have either finished sharpening or are waiting to be sharpened.
As far as carrying a knife, which is only in small part a weapon, I think everyone should have one on them at all times. I have had a pocket knife in my pocket almost every day for 20 years, and probably about half the time from age 10 till about age 24.
I did not vote as I don't carry a "concealed" weapon.
