In the republic of nyc where citizens rights are being stripped daily for the illusion of security and to fill the coffers of the city, your knife would be at the discretion of the politician's stormtroopers; the nypd.
If they decide to stop and frisk you and obtain your knife, they can deem it illegal upon their discretion, any further action after that would depend on the officers mood and their imaginary quota. If your are issued a summons and you are before a judge, he or she will tell you to keep the knife at your job or home and of course you will pay a fine. I know this from personal experience when my full size Benchmade Griptillian was confiscated from me while it was clipped to my pocket and i was on a date on 42nd street 4 1/2 years ago.
The current assisted opener problem, all started with manhattan DA cyrus vance's move to extort money from legit business a while back, thats why we can't have any reputable knife companies shipping to nyc anymore. In his bid for cash, he claimed his office was getting flooded with stabbing cases, and that any knife that could be opened with one hand is considered illegal within nyc limits; is this guy for real??? The sad reality is; any blade aficionado worth his or her salt knows these claims to be false and any stabbings that did occur in nyc confines were mostly with kitchen utensils or some other sharp object not a CRKT Heiho or any of my beloved Benchmade's, Spyderco's, SOG's etc...
