Why is Count Dookus lightsaber shaped differently?
From the Visual Dictionary: “As a Jedi Master, Count Dooku set aside the lightsaber he built as a young Padawan and created a superior one, as Jedi sometimes do. In creating his personalized design, he chose a configuration that had no connection to that of his master, Yoda, nor to the style in fashion at the time. Instead, he studied Jedi Archives records to create a lightsaber of the type that was standard in the heyday of Form II lightsaber combat. “The curved hilt of Dooku’s lightsaber allows for superior finesse and precise blade control. This design gives Dooku an edge when facing Jedi, who have mostly trained to use ligthsabers to deflect blaster bolts.” Dooku’s fighting style is different from anything we’ve seen before: he is more of a fencer who favors “long, elegant moves and incredible deftness of hand”, rather than the acrobatic somersaults and leaps shown by Maul, Obi-Wan, and Qui-Gon in TPM.
