I'm in PA and travel into NJ. Is it legal to carry a Sgian dubh in PA and NJ? Also, if the sgian dubh does not have an edge, then is it technically not a knife? Just out of curiosity, what about the dirk? A dagger is prohibited in PA. I'm guessing the Scottish dirk would be considered a dagger? What if the dirk isn't bladed? Does anyone know of any case law that would apply? Thanks.
