From what I could tell. Knives are prohibited. Used to be like that in the commonwealth of Puerto Rico. But the law changed in 2020 thanks to the NRA President Trump and governor Wanda garced The insular territory laws are very different. You are in the US but you are not in the US. Tough question. I can't find much information neither. I'd get there and go to the police department and ask them. Edit don't bring your expensive knives there. They might taken away. Play it safe. Good luck to you.
