Flint sword and spear


Stone-tipped throwing spears – Stone points unearthed in East Africa are the earliest known throwing spears, which human ancestors used to hunt prey around 279,000 years ago. Spears, consisting of sharpened obsidian tips attached to long handles allowed ancient humans (probably Homo heidelbergensis) to hunt animals from a distance and avoid dangerous confrontations with prey.
