2. Levallois technique - Wikipedia

   en.wikipedia.org/wiki/Levallois_technique

   John McNabb, archaeologist at the University of Southampton said of this: "The tools the people at Jebel Irhoud were making were based on a knapping technique called Levallois, a sophisticated way of shaping stone tools. The date of 315,000 years ago adds to a growing realisation that Levallois originates a lot earlier than we thought.

3. Knapping - Wikipedia

   en.wikipedia.org/wiki/Knapping

   Knapping is the shaping of flint, chert, obsidian, or other conchoidal fracturing stone through the process of lithic reduction to manufacture stone tools, strikers for flintlock firearms, or to produce flat-faced stones for building or facing walls, and flushwork decoration.

4. Lithic reduction - Wikipedia

   en.wikipedia.org/wiki/Lithic_reduction

   The Levallois technique of flint-knapping. In archaeology, in particular of the Stone Age, lithic reduction is the process of fashioning stones or rocks from their natural state into tools or weapons by removing some parts.

5. Stone tool - Wikipedia

   en.wikipedia.org/wiki/Stone_tool

   Knapped stone tools are made from cryptocrystalline materials such as chert, flint, radiolarite, chalcedony, obsidian, basalt, and quartzite via a splitting process known as lithic reduction. One simple form of reduction is to strike stone flakes from a nucleus (core) of material using a hammerstone or similar hard hammer fabricator.

6. Prepared-core technique - Wikipedia

   en.wikipedia.org/wiki/Prepared-core_technique

   The prepared-core technique is a means of producing stone tools 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.

7. Flake tool - Wikipedia

   en.wikipedia.org/wiki/Flake_tool

   These tools were able to be made by this "chipping" away effect due to the natural characteristic of stone. Stone is able to break apart when struck near the edge. Flake tools are created through flint knapping, a process of producing stone tools using lithic reduction.
