I have carried a pocket or belt knife most of my life and am very comfortable around knives of any sort. I rarely leave home without a knife on my body somewhere. However in today's world there are exceptions to every rule and some are more important than others. When I fly my knife is at home unless I bother to check baggage it can travel in. When I go to a courthouse or a police station or any sort of facility where they frown on the public being armed I leave the knife in the truck. If I were to go to church I believe the sgian dubh would also be omitted from my wardrobe. Besides common regard for the church it involves common sense on my part.
