Cuska
From elanthipedia
A cuska is a Rakash weapon consisting of rocks or metal weights, often sealed within leather pouches, that are joined to a handle with distinctive, sinuous chains. These pouches, or bare weights if they are not pouched, are always in groups of three, with one attached to the end of each chain like the head of a snake. Cuska may be used like a flail or thrown in a manner similar to a bola.
Cuska means 'snake' in Rakash, and this weapon gets its name from the specific style of chains used in its design.
