After watching the latest trailer, there are three main points I feel needs to be addressed:

  • How is the crossguard constructed? Is it similar to a double-bladed saber's construction of using multiple crystals to achieve the emittance of multiple blades?
  • Why does Kylo Ren's saber flicker? Seeing as the blue saber Finn was wielding in the trailer is similar to a good old Jedi lightsaber, we can conclude this isn't a new CGI style, and thus likely have an in-universe explanation. Are there functional differences to it - for example different combat characteristics, or perhaps it is unable to achieve zero energy leak?
  • Overall, is it a technological advancement, a "primitive homemade device" or simply a variant on a roughly similar level of technology?
  • Given that the rest of us also only have the trailers to go off of, I doubt you'd get any more than guessing games. Isn't your question asking people to speculate on unreleased material?

  • I was wondering if there was any talk of it in, say, novels and such Oct 23, 2015 at 6:40
  • Similar question: scifi.stackexchange.com/questions/73788/… As to Finn's Lightsaber, I'm pretty sure I read somewhere that it is Luke's, which is probably why it looks like a "good old Jedi lightsaber".

    "three main points" - pun intended.
