Whitefeather, you have a Georgia Firearms License right? Where on there does it say concealed license? I'd be interested in learning who told you it was such. In our state, with that license, it covers both open and concealed carry. A licensed person can do either.
I would advise you to take a look at georgiapacking.org or the website in my signature to help you further on your firearm rights in our state. They may be able to even help you with your knife question. HB 615, currently in our state hopper further expands our carry rights in our state and gets rid of the old Jim Crow public gathering law. It specifically does not include knives, although our current weapon law does.
GeorgiaCarry.org is an influential civil rights organization committed to not resting until the State of Georgia ceases all infringements upon the people's natural right to keep and bear arms that is protected by both the constitutions of Georgia and the USA. It's members include prominent legislators, captains of industry, members of the armed forces, police officers, parents, academics, lawyers, and citizens from all walks of life.
Vi et Consilio
