I will add my lawyerly weight to the discussion. Every U.S. state allows for the carrying of concealed weapons, however many states, California is one, where it is almost impossible to be approved for it. Also, the right to bear arms is seemingly restricted to the discussion of firearms, bladed weapons do not seem to fall under that category. I love my concealed carry permit myself, even though I almost never use it.
