Xiphos

The xiphos (Ancient Greek: ξίφος [ksípʰos]; plural xiphe, Ancient Greek: ξίφη [ksípʰɛː])^[1] is a double-edged, one-handed Iron Age straight shortsword used by the ancient Greeks. It was a secondary battlefield weapon for the Greek armies after the dory or javelin. The classic blade was generally about 45–60 cm (18–24 in) long, although the Spartans supposedly preferred to use blades as short as 30 cm (12 in) around the era of the Greco-Persian Wars.
