s by first preparing common stone cores into shapes that lend themselves to knapping off flakes that closely resemble the desired tool and require only minor touch-ups to be usable. In contrast to the production of core tools like

handaxes A hand axe (or handaxe or Acheulean hand axe) is a prehistoric stone tool with two faces that is the longest-used tool in human history. It is made from stone, usually flint or chert that has been "reduced" and shaped from a larger piece by kn ...

, where cores themselves were the end product shaped and trimmed down by removal of flakes, in prepared-core technique large flakes are the product and the core is used to produce them. This shift made it faster and more resource-efficient, as multiple tools could be struck from a single piece of starting material. Prepared core preparation techniques are grouped under the label Mode 3 technology. The best-known prepared core reduction method is the Levallois technique Prepared core technology was likely invented independently multiple times at different locations. The regular use of Prepared core technology is associated with large-brained hominins such as ''
