I’m my state there are restrictions, but they are pretty much accessory charges that you won’t get unless you are a dipshit. You do have to have a firearms permit to carry an automatic knife though, I am not aware of anybody getting charged with that and that alone.
What is funny is you can have a ka-bar on your belt not concealed and be fine, but you aren’t suppose to carry a pocketknife with a blade over 3.5". Also if the fixed blade knife is sharpened on both sides of the blade, that is a no-no, but if it folds it is fine. I think they just removed the ban on butterfly knifes or it has the firearms permit exemption now, but I would have to check to confirm.
As you can imagine, the gun laws make about as much sense and don’t do much to help the problem of violence.
