Repper22, please never ever think the TS operator at a precinet ( the officer holding the telephone transfer switch at the desk) knows anything at all about knife laws. You may have been lucky enough to have found one who knows a bit. Contact the legal division at OPP ( One Police Plaza) and inquire from them. They will tell you that any knife that can be flicked ( yes even holding the blade) can be deemed a gravity knife. Any knife that is a weapon by design is a dangerous knife, and any knife that the carrier states is used as a wepaon ( including self defense) is a dangerous knife. The city enforces the state law ( 265.01 and .02) differently than the rest of the state, but it has state wide implications since the courts have allowed this to stand. Quick and ready deployment is the thing the law attempts to ban, but it has become far to much an easy arrest in NYC where numbers of arrest count. The exposed knife is illegal with a few exceptions, but those who fall into those exceptions ( think construction workers) are subject to arrest for the gravity knife charge when the officer can flick it open. Officers have been allowed several attempts in court to get the knife to flick open. I wish I was an idealistic law student, but I am a former NYC LEO who has seen far too many people end up with a CPW arrest/conviction who where otherwise good guys.....carry a non locking non weapon knife in NYC and becareful elsewhere too....
