Answer:
Oldowan Tool
Explanation:
According to my research, the tool that is being described within the question is called the Oldowan Tool. Like described in the question this tool was made from stone cores with flakes removed from part of the surface, this then creates a sharpened edge that was most likely used for cutting, chopping, and scraping, usually meat from animal bones, and other materials to fabricate clothing.
