Patchwork is right - it is, for example, still illegal in Idaho to carry a concealed firearm or dirk-like knife in a mining camp. Which is fine except that nobody knows what a dirk-like knife is (it's a dagger) and there aren't any mining camps anymore. But, you know, if there were...
The Idaho State Constitution begins with a bill of rights before any governmental structure is specified. I quote Section 11 in full:
SECTION 11. RIGHT TO KEEP AND BEAR ARMS. The people have the right to keep and bear arms, which right shall not be abridged; but this provision shall not prevent the passage of laws to govern the carrying of weapons concealed on the person nor prevent passage of legislation providing minimum sentences for crimes committed while in possession of a firearm, nor prevent the passage of legislation providing penalties for the possession of firearms by a convicted felon, nor prevent the passage of any legislation punishing the use of a firearm. No law shall impose licensure, registration or special taxation on the ownership or possession of firearms or ammunition. Nor shall any law permit the confiscation of firearms, except those actually used in the commission of a felony.
