In NYS, the only exception for LEGAL ownership is an active duty Police officer or Peace Officer, and someone who uses the knife for fishing, hunting and trapping. Transfer and sale are illegal, so if you own one and have a VALID fishing, hunting or trapping license, you comply with the law. How to get one legally then is the issue. There are stores that feel they can sell you one ( in NYS) if you have one of those listed sports licenses, but that is not the wording of the law. The simple answer is that NYS law considers possession to be anywhere you have control over the item, therefore even in your home they would be illegal unless you fall into one of those groups I listed. get a life time freshwater fishing license ( I hope you fish). I can't suggest anywhere you should buy one in NYS as anyone selling it to you would be doing it illegally. If you have one, then the sports license would allow for ownership and carry to and from those sporting activities. As an EMT, you will be interacting with many LEOs from time to time. I suggest getting a sense of their tolerance towards these type of knives in your local area where you spend most of your time. Look up the law yourself too, and print out a copy of it if you end up owning this type of knife. NYS PL 265.01 is the law banning possession, and NYSPL 265.20 list the exception to the ban. NYSPL 265.20#6 is the fishing/hunting/trapping one.
