rossshady120, NY (outside of NYC) bans the carry of switchblades and gravity knives, and daggers and dangerous knives. I beleive the penal law does not mention knives per se in the school section, but you can check ( section 265.00). The Penal law states anyone one carrying a "dangerous knife" and is 16 or under is a youthful offender. I live in Nassau also and for the most part the knife laws is not as strickly enforced as in NYC, but they are enforced. There were a few arrest for knife sales last week at a train station on Sunrise highway, and about two months ago I was shopping at the Broadway Mall in Hicksville when two plain cloths officers checked three teenagers at the front of the Mall and discover one had a knife which the officer was able to flick open...the kid was in handcuffs in the back of the unmarked car in a minute.....I would not carry a knife to school and I suggest to only carry a small, non locking knife at other times....
