These original saberstaffs featured sophisticated designs, effectively a single mechanism with twin emitters on either end of a standard length hilt. The ancient Sith Lords took this miniaturization a step further with the creation of the Double-bladed lightsaber. With this modification, the power cell would only expend power when the energy loop was broken, such as when the lightsaber cut something, solving the power supply problem. The Sith design introduced an internal superconductor, which transferred the returning looped energy from the negative-charged flux aperture back into an internal power cell. The protosabers, while leaps and bounds ahead of the original lightsaber prototypes with their unstable blades, suffered from severe issues regarding energy consumption, necessitating a belt-mounted power pack. The early Sith lightsabers were simply an improvement on the preexisting Protosabers favored by the Jedi Order. Ultimately, the Sith wielded these weapons to mock the Jedi, a trait demonstrated by the regularly greater combat effectiveness the aggressive Sith Lords possessed. Despite this evolution, they are almost always distinguished by their scarlet bloodshine blades, a result of the red coloration usually taken on by synth-crystals. The design of these weapons changed greatly over the centuries since the founding of the Sith, sometimes featuring a standardized mold, other times being designed by individual wielders. Being of Sith design, these staff-weapons are sometimes referred to as Sith lightsabers, though are not to be confused with the genuine article. One of the variations on typical Sith lightsabers is the Double-bladed lightsaber. Also, most Sith weapons featured an overall more aggressive design aesthetic. Sith lightsabers almost always utilized Synthetic lightsaber crystals as opposed to the natural crystals favored by the Jedi, a fact they considered to be a mark of superiority. For the most part, the design differences are minimal, due to the typical modern lightsaber being based on original Sith designs.
Sith Lightsabers are a specialized type of weapon that catered to the needs and preferences of the Sith Lords. Double-bladed lightsabers, or Saberstaffs, are a popular form of lightsaber among Sith.
