There’s a photo going around that people want me to share here, in the hopes that Abrams himself will see it. I doubt that Abrams even knows this website exists, but I’ll relent.
First, I will explain why I think there’s nothing wrong with the current Lightsaber, and then the problem with my thoughts on it.
The lightsaber has the cross beams, and people are saying “well that’s not going to stop any blade from sliding down and slicing through the hilt.” What if the material the hilt is made out of can stop the blade? It seems that it can focus the blade in whatever direction, so it stands to reason that it could also deflect the blade of another lightsaber.
Argument against? Other lightsabers have been sliced in two, including Darth Maul’s own double bladed lightsaber.
Argument for? According to super geeky source material, there are materials in the Star Wars universe that may deflect or even short-circuit a lightsaber blade. The substances are phrik, cortosis and Mandalorian iron. In fact, Emperor Palpatine’s own lightsaber was made of phrik, as described in the Star Wars: Revenge of the Sith: The Visual Dictionary.
Therefore, the material the cross beam is made out of could very well be that same substance. Problem solved.
