The lightsabre
this is the formal 
 weapon of the jedi knight.
not as clumsy or as random as a blaster.  more skill than simple sight was required for it's use.  an elegant weapon.
it was a symbol as well.. 
to use a lightsabre well was a mark of someone a cut above the ordinary.......         obi-wan-kenobi
IT WAS PART OF A JEDI'S TRAINING TO CONSTRUCT A LIGHTSABRE OF THEIR OWN.  .
       In essence a blade of pure energy capable of cutting
       through almost anything, the lightsaber is the noble yet
       powerful weapon which the Jedi Knights have masterfully
     wielded for thousands of years Although each lightsaber is unique, the weapon's basic design remains the same. The handle, twenty-four to thirty centimeters long, holds a power cell as well as one or more crystals - seldom more than three whose purpose is to focus the energy released by the power cell into a tight blade-like beam.
The blade's color depends on the nature of
   the jewel it springs from, and while its length is fixed in the
    case of a single jewel lightsaber, lightsabers equipped with
    multiple crystals can have their length varied by rotating a
    knob which allows the focusing crystal activator to subtly
    modify the refraction pattern between the gem
After losing the lightsaber that had been his father's in a duel with Darth Vader, Luke Skywalker, in accordance with tradition, builds his own lightsaber as one of the final step of his Jedi training, before he confronts Jabba the Hutt in his palace on Tatooine.

The Lightsaber:
Although the exact details of lightsaber operation
remain shrouded in mystery, the general
technology is known. All the controls and components fit into
a compact handle 24 to 30 centimetres long. When the lightsaber is activated, a tremendous charge of pure energy flows from
the power cell. Thru a series of multi-faceted jewels
that focus the energy into a tight parallel beam.
Each saber beam has a unique frequency which determines the "feel"
of the blade, how it handles when cutting something or contacting
a force field or another saber blade. The frequency of each saber 
blade can be calculated from its blade colour and pitch it generates.
Sabers use between one and three jewels to give their beam a specific
frequency.

Sabers with a single jewel have a fixed amplitude, which determine the blade length. Other sabers with multiple jewels can alter their amplitude, and thus the blade length by rotating or varying the separation between the jewels. The best sabers use natural jewels, but, evidently, the Jedi can forge synthetic

  jewels with

a small furnace and a few basic elements.
The beam emits from a positively charged continuous energy lens
at the centre of the handle. The beam then arcs circumferentially
back to a negatively charged high energy flux aperture, usually 
set in a disk that also serves as a handguard. The power amplitude
determines the point at which the beam arcs back to the disk,
setting the blade length. The tight, arcing beam forms a blade 
of amazing strength.
A superconductor transfers the power from the flux aperture to
the power cell. Almost no energy is lost in the process - the
beam doesn't even radiate noticeable heat, though it does fluoresce
and hum. The saber loose power only when it cuts through something,
but not when contacting another saber blade. The Jedi must use
his strength and skill to force his blade against another saber
blade, no lightsaber can cut another's beam.
Controls at the hilt of the saber adjust the power cell capacity
and allow periodic recharging. Though exact duration figures are
not known, it is clear that Jedi can use their sabers for years
at a time before recharging becomes necessary.

Mandalorian Iron:
A lightsaber or lightwhip can cut thru almost anything,
except another lightsaber or lightwhip.
The only known material to withstand a lightsaber or lightwhip
is "Mandalorian Iron", but it is not known if this
metal can be found anymore, it vanished with the lightwhip.
It is now among "The Lost Sith Artifacts".

 

Force Objects:
There is many "Force" objects, created with the single
purpose of increasing the force of the owner.
The Sith Lord's had many such objects,
it is not know if the Jedi Knight's had such objects.
If they had, they are few and rare.
