Wanna hear a good one? Check out Maryland knife laws.
One cannot carry a switchblade (Automatic) knife with the intent to do harm.
I virtually always carry a knife, as a tool. I have a really nice, very high end automatic that I never carry because I have no idea how one would measure intent.
Typical Maryland insanity
The law as I understand it in TN is that a person cannot carry a switchblade knife “for the purpose of going armed”. I carry a gun “for the purpose of going armed”, so if I carry a switchblade at the same time, I figure I’m OK, right?
As a resident of Maryland, I am careful which knife I carry outside my home. When I check my keys on the way out the door, I also check my knife just because this state is so insane.
