I found another video that depicted a real life lightsaber. Instead of a blade of energy, this lightsaber was a rob made from multiple metals with high melting points. Once the rod was superheated to around 2,500 degrees Fahrenheit, it would glow and cut through pretty much anything. However, while the Star Wars lightsabers either cauterized or melted through anything they cut, this lightsaber not only melted and cauterized things but also set them on fire. Another feature that set it apart from Star Wars lightsabers was that its power came from a cable and power pack it was hooked up to. This was similar to the protosabers in the Legends continuity. They do not have the technology to make the lightsaber self sufficient like in the movies so they have to make do with the cable and power pack.
