Abacus

An abacus was a device with components that swung and clacked together. The Kupohan Azzur Nessin wore his beard in braided strands with golden beads that swung against each other and clacked like an abacus when he spoke.

Behind the scenes
Abacuses were first established to exist in the Star Wars universe in the Star Wars Legends sourcebook Pirates & Privateers, which was written by Timothy S. O'Brien and released in 1997 by West End Games for Star Wars: The Roleplaying Game. They then appeared in canon in the novel Heir to the Jedi, which was written by Kevin Hearne and released in 2015.
