I thought this reply posted earlier but it looks like it didn’t…

At least in my state the CCW permit is the same for all weapons. The process is very gun-centric; I suspect the various knives and knuckles and so forth were tossed into the law later. Part of the process requires to you take a mandatory pistol safety course which feels extremely silly if you’re only getting the permit in order to legally carry your knife around. But as we all know, gun and knife laws rarely actually start with the intention of making a lick of damn sense, and it’s all downhill from the start anyway.

It is theoretically legal to open carry legally classified “deadly weapons” in my state, although your risk of being hassled increases proportionally with the size and audacity of your openly carried item. All in all, I’ve never actually seen a cop care about anyone carrying any kind of knife here, and I’ve even had automatics (also on the “naughty list” in this state) given right back to me by cops without comment.
