Due to the vast array of scrapers there are many typologies that scrapers can fall under, including tool size, tool shape, tool base, the number of working edges, edge angle, edge shape, and many more.
Stone tools preserve more readily than tools of many other materials. [ 1 ] [ 2 ] So the oldest tools that we can find in many areas are going to be stone tools.

The oldest stone tools are about 3 million years old. Chopping tools mainly occur in the Olduwan (2.9 to 1.6 million years ago).

This method, which often uses punches made from bone or antler tines (or, among modern hobbyists, copper punches or even nails), provides a greater means of ...
The flakes are shaped using the lithic reduction techniques, allowing for creation of various tools such as arrowheads and handaxes. Two stone characteristics will determine whether one is able to chip away large enough flakes to make tools out of: whether the stone is of a cryptocrystalline structure, and how conchoidally the stone fractures ...
