I saw a butterfly knife for the first time when one of my friends in the camp brought it for self-defense. I was intrigued by its name and the unique design. I borrowed from him and tried to flip and use it and the first question that came to my mind was: is it even legal in the U.S? Because it doesn’t look like a safe knife to use.
As my friend is also from Alaska, he said “it is perfectly legal to use but I’m not sure about the other states”.
As I travel to other states quite often, I had to get clarity on its legality If I plan to use it there. I started deep research about it. After spending a lot of time on various platforms, official websites, forums etc. I finally got my answer. If you are also confused about the legality of this knife, I’ll clear your doubt in a minute.
