    So I guess that's ONE cool thing that happened in 2020.

    A handheld plasma torch. Not quite a lightsaber, but headed in the right direction. Hey! Elon! You paying attention?

    Yeah, they don't yet have the forcefield property that lets them hit each other, but like you said, it's a step.

    And that's the aspect of lightsabers that's going to be pretty much impossible to re-create.

    Well, never say never, I guess.

    This new plasma lightsaber thing is cool, but it's also a reminder that a lightsaber is a very dangerous weapon--to its user!--if used improperly.

    I think some kind of magnetic containment field is going to be as close as we get. It might even need some kind of physical component out at the end of the "blade." A reflector, a pole for the magnetics, something like that.

    To contain the "blade," the magnetic field would have to be solenoidal, which would mean the coil of the magnet would be visible outside the blade. Being a coil, it would have to be electrically insulated (lest it short to the coil in the opponent's lightsaber). For sturdiness, it would also have to either be of pretty heavy gauge wire, or be supported by a structure in the core of the blade. It would also have to be retractable/extendable. All of that bodes badly for a magnetic field as a solution.

    If you're willing to suspend a component out at the tip of the blade (and that would have to be attached mechanically to the hilt), why not just put a (very well-thermally insulated) extending rod in the core? Then duelers could cross blades and still burn/melt stuff with the saber. Yes, it's basically a metal baton disguised with a glowing plasma, but it would look pretty close to what's in the movies.
