For the original Star Wars film, the film prop hilts were constructed by John Stears from old Graflex press camera flash battery packs and other pieces of hardware. The full-sized sword props were designed to appear ignited onscreen, by later creating an "in-camera" glowing effect in post-production.

Lightsabers are designed to cut through most materials with ease due to the intense heat and energy of the plasma blade. However, objects with exceptionally high energy conductivity and density can dissipate the lightsaber's heat and energy, effectively resisting its cutting abilities.

According to the lore of the Star Wars Legends, a lightsaber is an energy blade composed of a diatium power cell and crystals that focus the energy into a beam. In the real world, a lightsaber could be created using plasma, as suggested by physicist Dr. Michio Kaku.

Most of the materials that can block lightsabers are rare metallic ores, the natural hides or shells of animals who are connected to the Force or the dark side in some way, and in some cases, even substances from another galaxy entirely.

"You wouldn't need too much force to land a deadly blow," he says. There are real-life techniques to push an opponent's blade away, but the perpetual lightsaber clashing shown in the movies' duels doesn't make any sense," Saleu says. "You aren't there to injure the weapon."

Realistic lightsabers from Ultra Sabers come in a variety of colors, each with its own meaning and symbolism. Some of the more popular choices are: Blue - The first real lightsaber fans saw, Anakin's blue blade that Obi-Wan hands over to Luke, is a combat saber wielded most commonly by Jedi Guardians.

The shading purple speaks to moral uncertainty, reconstruction, and recovery. Therefore, the individuals that used a purple lightsaber generally shared an affinity with both the Light and Dark sides of the Force.

While blue is not the only color used by the knights of old, it was certainly the most common one. This is evident by the abundance of blue lightsaber-wielding Jedi in the prequel trilogy with the color dating back to Star Wars' very first lightsabers.

Superman has been shown to fly through the Sun itself in addition to withstanding heat vision from fellow Kryptonians, both generating far more heat than that of a lightsaber. The only possible way for a lightsaber to harm Superman would be if the crystal powering the lightsaber were made of Kryptonite.

It burns. This means that unlike a blade, the damage isn't going to be confined to just the area you were hit. Your blood would be literally boiling inside your veins in the areas adjacent to the injury, and you'd have severe deep tissue burns all around it. Were lightsabers good weapons?

It appears rarely in the Star Wars universe - so rarely, in fact, that the current canon recognizes only one carrier of a white lightsaber. Ahsoka Tano, the former Jedi Padawan who aided in the rebellion against the Galactic Empire, is acknowledged as the sole possessor of the white lightsaber.
