Turnbull, sorry if that came across as a personal slight on you, it wasn't intended that way. The things is, if you've never needed it for protection in the whole nearly 10 years now you've carried, it kind of tells a story about the need v probability SoCal refers to in his later post. If its concealed, its not deterring would be attackers either.

SoCal, the things you mention aren't designed with the sole intention of killing people, so there's a difference. Arguably, knives, but most knives have an everyday general purpose and most are perfectly legal in your kitchen drawer.
