Here in Va, we have a concealed carry law, but in most localities, especially rural areas, we have always been able to carry unconcealed knives, or even guns, so the sgian dubgh is no problem as long as it is not concealed. I do know someone who was arrested for having a concealed weapon, when a folding Buck knife was partially covered by a jacket. It was thrown out of court because it wasn't concealed if the officer could see it.
