Sling (weapon)
Kestros

The kestros (also known as the kestrosphendone, cestrus, or cestrosphendone) is a sling weapon mentioned by Livy and Polybius. It seems to have been a heavy dart flung from a leather sling. It was invented in 168 BC and was employed by some of the Macedonian troops of King Perseus in the Third Macedonian war.
