In NY you can get a fishing licnese and then you can legally own them in your house and use them to go to and from the lake. Right now they are not legal even in your house without a fishing/hunting/trapping license. The law is some what vague about selling them to a FFL dealer so that he may offer them for sale to Police. The law allows for the sale of them to police and peace officers, so if you really have no interest you may want to call a few gun shops and see if they have any interest in buying them ( with in NYS). I live in LI and all the Gun stores here sell them. If you don't want them, and feel the need to get rid of them legally this is the best method. You may want to look at another site that is all about this type of knives and see since there are a few NY collector's there if they wish to talk off line to you...try Talkblade.info and see what happens...the law stinks, but it is the law......
