Chances are that you have seen a lightsaber at one time or another, whether on the evening news or down at the local cantina. Therefore you know that a lightsaber is an amazing and versatile device that is able to cut through nearly anything in a matter of milliseconds.

Have you ever wondered how these remarkable weapons work? Where does the energy come from, and how are they able to contain that energy in a rod-like column of glowing power?

In this article, you will have a chance to look inside a lightsaber and discover the source of its incredible characteristics. Let's get started!

It's All In The Handle

A lightsaber is a unique device, created by hand -- the controls will be slightly different on each individual lightsaber that you buy. But all lightsabers share the same general characteristics. If you were ever to pick up and examine a typical lightsaber, here are several things that you would immediately notice:

• A lightsaber is normally about 30 centimeters long, about the size of a large flashlight.

• At one end is the hand grip, belt ring and on/off switch (a.k.a., the Activation Matrix).

• At the other end there is the blade arc tip and stabilizing ring.

• Somewhere on the case (generally near the blade end of the lightsaber) you find one or two adjusting knobs for blade power and blade length.

When you turn on the lightsaber (*see important safety tips), you will notice the blade rapidly extending to its set length. You can adjust the length using the blade length adjusting knob. The lightsaber blade will make a distinctive sound that is typical of an arc wave energy field. You will also feel a gyroscopic effect in the handle, which again is a distinctive characteristic of the arc wave blade. This gyroscopic effect can take some getting used to, so be sure to handle any active lightsaber with extreme care until you are completely familiar with its feel and handling.

Important Safety Information A lightsaber is not a toy! Keep it out of reach of children at all times. Lightsaber locks are required in most states. There are two ends to any lightsaber -- one end has the belt ring, while the other end houses the blade arc tip and blade emitter. NEVER point the blade emitter of a lightsaber toward your own body. NEVER look down the "barrel" of a lightsaber, even if you are "sure" it is in safe mode. If you accidentally activate the lightsaber, serious injury could result.
