With all of the security and such since 9/11 no one is doing anything above pickpocketing (if even that) in most parts of NYC that a tourist might go to; the whole SWAT-style police on streetcorners with MP-5's or M-4's seems to dissuade crime, I have no idea why though....
I don't think you'd be able to get one of the plastic knives through, some of the detectors scan for density instead of metal alone. Besides, if you're caught with a polymer dagger it won't look good for you legally. Pack a flashlight or kubaton if you're really dedicated to a SD device.
A bit off topic, but what are the fixed blade laws for NYC? Would an Emerson LaGriffe be a no-go?
