Oldowan Tools

Oldowan tools are rocks that have chipped edges, usually made with other rocks to chip the ends to make a cutting or chopping edge. It usually only took one blow from another rock to create a sharp edge flake. The best flakes are from crystalline stones such as quarts, basalt, or chert. The reason why this is so important is because it tells us that early hominid could recognize the the types of different rocks.

Many flakes were also created with a "core" stone, a rounder, softer rock. The "core" stone was deliberately rounded to help with making tools and to help with control.

The flakes were mostly used for cutting, for cutting grass and getting pieces of meat from game. Flakes were also used as a shovel for getting to bugs underground.

Acheulean Tools

These tools look a lot like Arrow Heads but not as sharp and not made from obsidian. Acheulean tools were made around 1.5 million years ago and we first found them in East Central Africa. The tools below were associated with Homo ergaster and western Homo erectus.

The way these tools are made is, chipping the sides of the stone to make a bifacial cutting edge, shaping the tool into a recognizable tool form and, different shapes and sizes of tools were made it just depended on what they planned on using them for. The tools were made from glassy lava, quartzite, flint, and chert.

Making these tools requires skill and strength. Some of the largest shards were made from boulders or very large rocks. These heavy have refined edges and are shaped in a symmetrical shape.
