Final answer:
Acheulean tools are iconic teardrop-shaped implements of the Acheulean industry, replacing the cruder Oldowan hand-axes. They were used for cutting, scraping, and chopping tasks, and were an improvement over earlier tools. Acheulean tools are distinct from Oldowan tools as they are modified on both sides, creating a symmetrical tool with two faces.
