I know that there are laws restricting concealed weapons and whatnot. But are there any restricting weapons that are out in the open? I ask because my little brother and just about all of his friends carry very large knives around wherever they go. (Typically large hunting knives) just strapped to their hip. I mostly wanted to make sure no laws were being violated on his part.
(In the case that this is a state dependant thing, I live in Washington State, about an hour north of Oregon.)
