Knife laws vary allot by city and state. In Colorado I believe the maximum length allowed is 3.5 inches in blade length. This sounds simple but can even be a grey area because some knives like Spyderco have a part of the blade thats not sharpened and technically part of the handle. NYC used to be very knife unfriendly and you could get charged with carrying a gravity knife if the knife could be flicked open in any way. Good news though as it sounds like that changed https://reason.com/2019/03/28/federal-judge-rules-new-yorks-insane-gra/ https://reason.com/2019/03/28/federal-judge-rules-new-yorks-... There was still a case in NYC of a chef who was charged with something for carrying a very small pocket knife on his way home from work. He was charged with something for the pocket knife but from what I remember it was totally okay that he was carrying a bunch of large chefs knives in his backpack. Its important to read and understand the law as well as how its actually enforced.
