Lightsaber

"This was the formal weapon of a Jedi Knight. Not as clumsy or random as a blaster. More skill than simple sight was required for its use. An elegant weapon. It was a symbol as well. Anyone can use a blaster or a fusion-cutter, but to use a lightsaber well was a mark of someone a cut above the ordinary." ―Obi-Wan Kenobi

Mechanics
"The components are fairly simple. Every lightsaber has a standard power source, the same type used in small blasters, even in glowpanels. They last a long time, though, because Jedi should rarely use their lightsabers. […] One of the other crucial pieces is a focusing crystal. The most powerful and sought-after gems are rare Kaiburr crystals. However, though lightsabers are powerful weapons, their design is so flexible that practically any kind of crystal can be used." ―Luke Skywalker, to his students

The typical lightsaber hilt consisted of a metal cylinder between twenty-four and thirty centimeters in length. However, the size of individuals hilts varied drastically, as the weapon was tailored to the creator's specific needs and preferences. The hilt had a pommel cap at the bottom which sometimes held a backup power cell. The lightsaber mechanisms were contained within the hilt. High levels of energy generated by a high-output Diatium power cell was unleashed through a series of focusing lenses and energizers that converted the energy into plasma. The plasma was projected through a set of lightsaber crystals that lent the blade its properties and allowed for the adjustment of blade length and power output. The ideal number of crystals was three, though only one was required. A power insulator was installed on the hilt to protect the wielder from any energy discharges. Activating the lightsaber usually required a button of some sort. A blade power adjustment knob was sometimes installed to allow the wielder to vary the power of the blade. A discharge energy cell could also be installed to increase a lightsaber's power output.

Once focused by the crystals, the plasma was sent through a series of field energizers and modulation circuitry within the emitter matrix that further focused it, making it into a coherent beam of energy that was projected from the blade emitter. The blade typically extended about a meter before being arced by the blade containment field back to a negatively charged fissure ringing the emitter, where it was channeled back to the power cell by a superconductor, completing the circuit.

Cutting power
"By the Force! I thought a lightsaber could cut through anything. The walls are barely scratched. The only thing that can resist a lightsaber is… Mandalorian iron!" ―Exar Kun, regarding Freedon Nadd's tomb

A lightsaber blade was a mass-less form that neither radiated heat nor expended energy until it came into contact with something solid. The power of the energy blade was so great that it could cut through almost anything, although the speed through which it cut depended on the density of the subject. One important note about lightsaber wounds is that they rarely bled profusely, even when a limb had been severed. This is because the energy blade cauterized the wound as it passed, and thus even a severe wound did not tend to bleed heavily.

When cutting through dense material, the immense electromagnetic field generated by the arc caused resistance rather than letting solid matter enter and interrupt the arc. This gave the blade a feeling of being solid when immersed in dense material. Rarely, some solid materials could actually pass through the electromagnetic field and short out the arc. Other electromagnetic energy fields and coherent energy were also repelled by lightsabers' arcs. These include most force fields, blaster bolts, and other lightsaber blades.

Combat
"These weapons are not playthings. A lightsaber is a dangerous and destructive instrument, a powerful blade that can strike down an opponent, or a friend, if you're not careful." - Luke Skywalker Lightsaber combat was the preferred fighting method used by lightsaber wielders, many of the forms and styles being designed to compensate for the gyroscopic effect inherent in lightsabers, and take advantage of the Force-sensitivity common in most wielders. The different styles of lightsaber dueling were initially based on ancient sword-fighting techniques. Throughout the millennia, these many combat styles were refined into the seven "classic" forms that serve as the standard, and numerous other fighting methods that call for advanced levels of skill. Lightsaber combat was difficult to master for a number of reasons, one of them being that all of the weight a lightsaber had was in its hilt, and the gyroscopic effect caused resistance to changes in motion, or built up momentum so quickly than an untrained wielder could lose control of the weapon.

Rituals
Lightsabers were an integral part of the knighting ceremonies of the Jedi Order. During the ceremony, a Padawan would have his or her Padawan braid ritualistically severed by the presiding Jedi Master. This event would often be witnessed by a number of fellow Jedi, who would stand in a circle around the Padawan with their lightsabers ignited.
 * Knighting Ceremony

Only three Sith "knighting" ceremonies are known; a lightsaber was only used during one of these. During the ceremony, Galen Marek was made to kneel before his master, while Darth Vader simply lowered his lightsaber next to both sides of Marek's head, formally declaring the Force Adept his apprentice.

"I have something to return to you. It is a product of your own hands which you once entrusted to mine. In returning this lightsaber, I return your trust." - Mace Windu
 * Concordance of Fealty

The Concordance of Fealty was a Jedi tradition of entrusting one's lightsaber to a fellow Order member. This exchange represented a serious, even sacred bond the establishment of a reciprocal, master-less learning relationship.
