Legal knife size in new york state?

Answer 1

Copied directly from another WikiAnswer: I've had a lot of discussions about this lately, as a certified self defense instructor. The law in New York City is vague, but goes something like this: -Blade Length cannot exceed 4" -Blade cannot open automatically (switch blades, etc) or with assist (spring opened, gravity or inertia knives) -Knife must be concealed. (This means no visible aspect. No pocket clip, no handle, no nothing) I say the law is vague, because it also dictates that a knife cannot come to a point. Yeah. (If you're looking for a knife that has a good argument for "Doesn't come to a point," check out Cherusker's Lapu Lapu Corto or LLC.) Also, there's a difference between what's legal, and what police will arrest you for. For example, butterfly knives are technically legal in the city, but the police will have good reason to grill you on why you need to carry one. So, if the police ask why you're carrying, you better have a darn good reason. Lots of people use knives for work, or to assist in projects, those are good reasons. If you're carrying for Self Defense or because "It's my favorite" or because you're a mugger, those are not good reasons. ( http://wiki.answers.com/Q/What_size_knife_is_legal_to_carry_in_New_York )
