NYC has extremely harsh rules for knife carry, dating back to the "West Side Story" days in an effort to fight switchblades & gravity knives. These rules are now being used against folks carrying box cutters & Leatherman knives, a lot of which are carried for legitimate purposes, i.e. contractors, store clerks, etc. It has gotten so bad I have taken to carrying a copy of the NYC Admin Code in my wallet, which states the maximum blade length is 4 inches, is not able to be opened by one hand via a "wrist flick" or some other means. It also has a ruler to show that my EDC Bucklite blade comes in at a whopping 2 7/8 inches, well within code.
