NIB -- I'm no expert on Texas, but methinks you have something kind of mixed up. No idea what their fixed blade laws allow, but you are allowed to carry a 5.5" folder concealed.
I believe in most states what length one carries opoenly in fixed blades sheathed is mostly limited by your inseam. Then again, am not all that sure that swords are legal to carry.
I think if you go to the BDF, a search on laws will provide threads with links to all state laws.
