Bubba, something being a common law in a lot of states, and something being the law in the United States are two very different things. Alaska is part of the United States, and I guarantee you that no one is going to run afoul of the law for carrying a sgian dubh in their sock in Alaska. In Alaska it is legal to visibly carry a firearm... not in government buildings or schools, but in most places. At least that was the law when I left. Since coming to Japan they have changed the concealed carry laws so that as long as you have no criminal record you no longer need a permit to carry concealed. I don't know if that may have affected the law about carrying visibly, but I doubt it did.

However, after re-reading all the posts, I realised that you never did actually say that the 3 inch rule was the law in the US. You mentioned the 3 inch rule and then stated that in the US it doesn't matter if it is part of traditional attire or not. I put those two sentances together and thought that you were saying the three inch rule was the law in the US. Later when you said "here" again, I was thinking the US, but you could have just as well meant Wisconsin. So, if I misinterpreted what you were saying I apologize for the misunderstanding.
