Carrying a weapon in New York City?

Question

I have one of these things (not that many knives on it though) http://specials4u.biz/retail/images/SKA13_400px_72dpi.jpg

that my friend got me from a different country which does not have laws against this. While the gadget is closed it measures 3 3/12 inches long. Is this legal to carry in NYC? I heard that I can carry it if others can see it- but how can that happen?

Also, I live in New Jersey in the summer- same laws as NY?

Thanks

It's called a Swiss Army Knife, and it's legal if the blade is less than 4 four inches.
