I have several speedsafe knives in my collection. I was talking to a friend recently and he told me the laws in some counties in MD have been changed to make carrying speedsafe spring assist knives unlawful. I have no code cites, just this comment. The only regulations I am aware of concern automatic knives, defined as operated using a button on the scale. Does anyone have a definitive answer on where in MD speedsafe knives are prohibited, or otherwise regulated as other than a pen knife?
