Read the law here : https://www.nysenate.gov/legislation/laws/PEN/265.00
Is it updated. 265.00 is the definitions, 265.01 is the violations, and 265.20 #6 allows an exemption for the limited carry of switchblades and possession of them for these uses ( use to say gravity knives there too). I don't see where you are reading automatic knives being illegal?
I remember that issue with the museum displaying the old Camillus autos that were originally made in NY. At the time, I believe the museum was actually ordered in court to take the springs out of the knives.The entire definition of "automatic knives" was made up so a museum could legally display knives made in NYS years ago. A local Sheriff had made them removed their collection on display. The exemption was added with the new term automatic knife for the purpose allow the displays to continue.
So, technically, the only 100% legal way a NY resident with a fishing/hunting/trapping license could obtain an auto would be to travel next door to a state like Vermont, Massachusetts or Connecticut and physically transport it with them back to their residence by car (I assume with the knife locked securely in the trunk and license present in vehicle). That would obviously be the only option if sellers in the state are prohibited from selling to civilians and, of course, federal law makes selling autos by mail order across state lines a crime.The seller is not allowed to sell to anyone other than law enforcement and military. I too have heard of sellers saying they would sell to someone with the fishing/hunting/trapping license. That is not a legal sale. I can only think a seller may feel once the sale is complete the new owner has qualified legal possession of the knife, but the transaction itself is still a violation.
If I didn't know any better I would say that the laws are intended to make things so difficult that most people won't even bother!So, technically, the only 100% legal way a NY resident with a fishing/hunting/trapping license could obtain an auto would be to travel next door to a state like Vermont, Massachusetts or Connecticut and physically transport it with them back to their residence by car (I assume with the knife locked securely in the trunk and license present in vehicle).
