From what I've been told, it's legal to own a bigger one, just not legal to carry
I believe that’s correct as well. 2” is the blade length limit for any automatic or “assisted” opening knife. Beyond that, it is illegal to have on your person or sell/trade. To me that says if you’ve already got something longer, fine…just never actually do anything with it other than leave it at home.
Also illegal to bring any kind of knife over 2.5” on school grounds.
Illegal to conceal any fixed type daggers, which is probably why you see the M/C guys have a knife strapped to a fork tube or their hip/thigh.
And there are five states where an auto or assisted knife of any kind are illegal. And of course D.C. as well.
