Paul,
I am not sure about it being a law, but around here they can arrest you and take the knife if it has a blade over 6" long. Hunting knives carried in a scabbard are in a gray area as it seems to depend on the person that sees anyone with one. I think that if you are in the woods hunting, then they are ok, but not to carry in town or on your person. I have asked a couple of our game wardens about that and received two different answers, plus our police department can't seem to agree on it either.
