Lightsaber nunchucks were really cool, but also really useless. The weapon consisted of two lightsabers connected by a chain of cortosis. Not an "elegant" weapon, as Obi-Wan might say, but a bad-ass, vwing-vwing, wow-the-crowd, super-sweet weapon. Unfortunately, it hardly ever worked. Lightsaber nunchucks caused more cut off limbs than any other lightsaber variant. More of a circus act, really.
