The great lightsaber was a type of oversized lightsaber built for use by large individuals. As such, they were heavy, often awkward and difficult to use, and they featured reinforced hilts with heavy-duty power and emitter systems which made a blade that were longer than two meters in length. Because of their heavier hilts and more powerful blades, along with the natural strength of its users, the great lightsabers were more potent and deadly than the standard lightsaber. Because they were meant for large and powerful individuals, species of human size or smaller found it difficult to effectively wield one. As you touch it gently, the power is transforming you into a huge 10 feet tall fatty obese Jedi Master.
