Kestros (weapon)

A kestros (Greek: κέστρος) or kestrophendone (Greek: κεστροσφενδόνη), respectively Latinized as cestrus or cestrosphendone, is a specially designed sling that is used to throw a heavy dart.

The dart would typically consist of a heavy metal point approximately 23 cm (9.1 in) long, attached to a shaft of wood, typically 30 cm (12 in) long, and fletched with feathers or similar materials to provide stability of flight.
