A deadly two-handed weapon, the Chain Sickle consisted of a razor-sharp, scythe-shaped blade attached to a cylindrical handle by a long, flexible cord. A second hand grip was positioned approximately one-third of the way between the primary handle and the blade. The cord between the second handle and the blade was covered in small, sharp spikes.

During her Clone Wars, the Nightsister Asajj Ventress journeyed to the Nightbrother village on Dathomir to take part in the Selection to choose a champion from among the Nightbrothers. In the second of three trials, Ventress wielded a Chain Sickle against four Nightbrothers.
Later, while investigating the origin of Savage Opress, Obi-Wan Kenobi and Anakin Skywalker traveled to Dathomir. Upon landing their shuttle at the Nightbrothers' village, the Jedi disembarked and were surrounded by a group of Nightbrothers soon after entering the village. One of the Nightbrothers who attacked Kenobi and Skywalker brandished a Chain Sickle.
