Shaping flint and obsidian into blade cores provides flakes that are razor sharp. This technique was practiced worldwide in the archaeological record to get the most out of a small amount of raw material. Once shaped in this way, flakes coming off the core can be blanks for many different kinds of tools such as blades, scrapers, burins, gravers, and points.
