Have to be careful. As others have said I can legally CCW as many pistols as I want. But if I have a blackjack or a knife with a blade over 4" I'm probably going to jail. They are not legal in most places to carry either openly or concealed. A weapon is to protect yourself with. If you get busted for what is considered an unlawful weapon you'll probably lose your CCW and maybe your right to own a gun if it's a felony in your area.
