A Lightwhip, also known as an Energy whip or a Laser whip, was a rare variation of the Lightsaber.
Lightwhips generally functioned on the same principles and mechanics as lightsabers, emitting a coherent beam of energy that was used as a weapon. However, rather than the straight, meter long blades emitted by standard lightsabers, lightwhips featured long, flexible blades that often exceeded several meters in length. Instead of one large crystal, they contained multiple small crystals and the plasma in the blade had no cell barriers to keep it straight. It appeared standard for these weapons to emit only single blades, though "cat o' nine tails-style" lightwhips with multiple tassels are not unheard of. Like lightsabers, lightwhips came in a variety of colors and shades, including red, orange, pink, yellow, blue, and green.
Wielded in the same manner as a proper whip, the lightwhip was a rare and exotic weapon, an unfamiliar occurrence among traditional duelists. Due to this, lightwhip wielders enjoyed a considerable amount of leverage over opponents. Along with its rarity, lightwhips also featured copious range, the long, flexible energy strand allowing the wielder to attack from a range of several meters. The weapon was also difficult to defend against, as it could simply flex around an opponent's blade when he attempted to parry. When multiple tassels were included, the whip was able to overwhelm the defenses of enemies by attacking them from all sides. However, lightwhips featured just as many drawbacks as advantages. The lightwhip blade was difficult to control, able to just as easily maim an untrained wielder as an opponent, and was weaker than the standard lightsaber blade as it could not always penetrate durosteel armor or walls, and many substances could survive from a direct hit. It needed to be swung wide to gain momentum for attack, and it was difficult to use defensively as flexible tassels are not well suited for parrying, leaving the wielder vulnerable to both great speed and brute force. In fact, lightwhip blades were even known to short out violently when struck with enough force. Efforts to compensate for the inherent weaknesses of lightwhips included the addition of tassels composed of solid matter. These variations in composition also allowed the users to attack there opponents on two fronts, as the different behaviors of the energy beams and the solid strands left the weapon highly unpredictable, as well as taking advantage of flaws in Jedi training, which only prepared combatants for a weapon that was one or the other. However, this innovation was not a complete solution, as the weapon still possessed the weaknesses. Also, the inclusion of the solid strands could be countered through the use of the Jar'Kai dual-blade technique, the method being to ensnare the energy strand with one blade while shredding the solid tassels with the second.
