Awesome new idea for you magnet owners
I just had an awesome idea! I know things exist now that can be turned on and off with a magnet but how about a magnet switch in a lightsaber. In star wars lore many sabers were created that could only be turned on with the force. They also included complex locking mechanisms inside so that a stolen saber took time to decode and learn to activate. We could simulate that with a switch in a saber where only you as the owner could turn it on!
