If a Bowie is seen as a chopper, then any real Bowie will exceed the 5.5" blade length, and be illegal to carry under most circumstances, anyway.
San Antonio has a city ordinance prohibiting knives with blades that lock in the open position, with a blade length less the 5.5". (That keeps the ordinance from conflicting with the state law against blades over 5.5".) Please do notice that this prohibits MOST folders currently on the market, except slipjoints.
I would avoid ALL assisted-opening folding knives in Texas until there is a really definitive answer from the highest appeals court in the state, and preferably, also, a clear definition in the penal code. Well, actually, being a peace officer, I can carry virtually any weapon legally, but I am meaning from a hypothetical viewpoint, as if I were a private citizen, and someday, of course, I will be.
I don't like AO knives, anyway. It's a selling point for some, and a way for knifemakers to display their artfulness, but I want to feel the lock engage as I thumb a blade open, or else carry a fixed blade. Texas law is fixed-blade-friendly.
As for retail stores selling AO knives and Bowies, well, wake up and READ the law. One can possess certain things in one's home or business that cannot be carried in public.
