For the past few days I've been pondering on how to make a deployable energy sword. Esentially one with blades that can be compressed in to the hilt. I figured I could use spring steel wire as a frame and some sort of multi-layer cloth or plastic for the blades posibly with LEDs or something for lighting but the devil is finding a way to cram all of it in the handle and still having room for a battery and the release mechanism. Any ideas?
