I went looking at every state I’ve lived in and the one with the most restrictions was Texas, obviously states like New York or California will be more restrictive, but the only real restrictions that I found outside of new england / California, were switchblades or “automatic opening knives”, and carrying in locations like schools and government buildings, which I expected. I used to carry a 8” hunting knife (13” overall) when I did a bunch of outdoor work, now I carry a smaller 3” folding pocketknife.
