I assume they are legal here as I was told there were 8 Federal agents policing the gun show undercover. Now I don't know if that's true or not but is what I was told by the fellow I bought the Enfield from. This was their first show and perhaps the old timers were telling them a story. There were police at the door checking firearms coming in. I've never seen the police actually enter any show, just at the front door. Switchblades are supposed to be illegal but I've seen a lot of them in my lifetime. They have a mechanical open feature which the gravity knives do not.
