The lightsaber is an undeniably awesome creation, and it wouldn’t be a stretch to claim that it is the single most famous component of the Star Wars universe, more widely recognized than Luke Skywalker, the Death Star, TIE fighters, or any other canonical element. Even the sound of the lightsaber, that distinctive undulating hum, is instantly recognizable.
Many fans wonder: What are lightsabers made of? And more specifically, what are lightsaber blades made of? While the weapon appears simple, the answer involves plasma energy, kyber crystals, and advanced technology within the lightsaber hilt (handle).
If you’re really serious about lightsabers, you should understand what goes into the making of these powerful sabers. This is as good an occasion as any to take a look at the inner workings of the world-renowned lightsaber blade, as it exists in Star Wars canon as well as right here on 21st-century Earth.
Let’s begin with the lightsaber as it exists in the cinematic world originated by George Lucas and his collaborators. Remember, when we talk about the blade of a lightsaber, we mean the damage-causing cylindrical portion that protrudes from the hilt. The blade can cut with equal effectiveness from any direction, and the force of its impact does not depend on the physical strength of its wielder. That’s why younglings must be extremely careful when handling their lightsabers—it’s easy to hurt yourself with these things because even momentary, casual contact can lead to serious injury.
What are these blades made from that makes them so dangerous? Not light, despite what the name might seem to imply. Lightsaber blades are pure plasma, a moldable electromagnetic state of matter that, when emitted from a hilt, can slice through most known substances with ease. Lightsaber plasma, in addition to its combat utility, is also bright enough to use as a close-range source of light.
Plasma is commonly associated with the planet Naboo in the Star Wars universe. On Naboo, plasma can be found in abundance in the planet’s crust, from which it is frequently extracted and then put to practical use as an energy source with wide-ranging applications.
In Star Wars canon, a lightsaber blade is created when energy is focused through a kyber crystal inside the hilt. Kyber crystals are Force-sensitive minerals (found uncommonly on planets throughout the universe) that resonate with their wielder, allowing Jedi and Sith to channel plasma into a stable blade.
The crystal determines the blade’s color and helps regulate the weapon’s power. When properly attuned, the kyber crystal generates the iconic blade that defines the lightsaber.
Traditionally, kyber crystals could be found in relative abundance in the sacred Jedi-controlled Crystal Cave of the planet Ilum. It was customary for Jedi younglings to explore the Cave to find their own kyber crystal, in a rite of passage known as the Gathering.
In the Star Wars universe, lightsaber blades are made of plasma energy controlled by a kyber crystal and a magnetic containment field. In the real world, functional combat-ready sabers are constructed differently.
Ultrasabers lightsabers use durable polycarbonate blades developed for illumination, durability, and safe sparring. High-impact polycarbonate tubing allows duelists to recreate lightsaber combat safely while maintaining the look and feel of a real lightsaber blade.

What is a lightsaber blade made of in our world? The lightsabers available through Ultrasabers do not employ plasma energy. Instead, their blades are made from tough polycarbonate tubing, with film inside to promote strong illumination. Polycarbonate is a thermoplastic polymer noted for high impact resistance. That’s what makes our lightsaber blades so effective for sparring purposes. They can even be brought into play in full-contact saber battles without fear of damaging them.
Mid-Grade blades and Heavy-Grade models are made from clear polycarbonate that has a metallic appearance when the blade is turned off. Ultraedge models are made of white polycarbonate, which looks “fuller” because the illumination carries all the way to the edges of the blade walls. The clear polycarbonate and the white polycarbonate are equally durable; however, it should be noted that the blade walls of heavy-grade models are substantially thicker than the others.
