I live in Maryland...I know...lucky me. Anyways, after hearing many different people pontificate about the legal length for a knife in the state, I decided to look it up in the Annotated State Code. I had heard things like "under 4 inches," "four fingers," "smaller than the palm of your hand," "can't be carried in your pocket." Well, after an afternoon of digging online, I found out that there is not a state mandated limit in Maryland. All that is prohibited are basically any kind of fixed blade or switch blade or gravity/butterfly knife. Any and everything else is legal. And since this was the annotated stated code, it listed the court rulings on each provision. And there are two that support our right to carry folding, locking blades. On the other hand, I know a few police officers, and they have said that if I get into trouble, having a knife on me, of any sort, is only going to get me in more trouble. So damned if you do, damned if you don't. I'll take my chances and be prepared.
