Video: This totally bad arse “lightsaber” uses a thin burning flame as its blade. It’s a firesaber, sure, but it looks like so much fun to handle (and probably just as dangerous to play with) that I’m going to consider it a lightsaber anyway.
Made by Sufficiently Advanced, the burning lightsaber uses a nichrome ignition, a methanol and acetone fuel mixture, butane as a propellant, a valve for control, and Star Wars lightsaber sound effects for good measure.
