Dale-
When it comes to knife and gun laws in NYC...who knows. The laws change from year to year. You have to dig hard and deep to find out what the latest changes to the statutes might be....however, it's safe to assume that the laws about knife and gun possession will always become more, not less, restrictive. This is the "New York Mentality"...restrict, control, totally progressive-liberal, and paternalistic. If you run up against the "law" for any reason....you are in deep trouble, especially if it's a gun/knife violation. The courts will not be on your side. Our wonderful communist/socialist Mayor, just reversed the "stop, question, and, frisk" laws, that actually worked, and got results! NYC proper is the worst. Very, very restrictive firearm/knife laws. Very few get permits to carry "concealed". You have to show cause and then prove your "need" for a concealed-carry permit. However, if you know some low people in high places, you'll get the permit. NYS laws vary, but they are generally more gun and knife friendly. In NYC you need a permit to own a firearm and another permit to own a rifle/shotgun, and they both cost a fortune to get, and to renew, every few years. New York City....the 'Gestapo City'....if, you get caught.
