I always thought one had to be a trained Force sensitive to construct one, which is among the final tests of becoming a Jedi. Apparently if you didn't build the device properly, it would blow up in your hand upon first activation. Which is also why they are not mass produced. Luke Skywalker's first lightsaber was his father's, it was blue. Luke built his second one, which was green. Vader later noted this as a sign his skills were "complete". EDIT: I'm now reading that at some point lightsabers were indeed mass produced. I think that ruins the fun of the mythology around the weapon. EDIT2: Now I'm reading that the crystal must be infused with the Force by the builder before construction. Fun mythology back on?
