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. Tranchet flake - Wikipedia

   en.wikipedia.org/wiki/Tranchet_flake

   Knapping freehand allows for greater control while supporting the core against the leg makes the work easier. The technique used to make the tranchet flake was used in the making of other tools as well, including tranchet axes (characterized by their trapezoidal or triangular shape) adzes, and even tranchet arrowheads. Unlike chisel arrowheads ...

5. Lithic reduction - Wikipedia

   en.wikipedia.org/wiki/Lithic_reduction

   Normally the starting point is the selection of a piece of tool stone that has been detached by natural geological processes, and is an appropriate size and shape. In some cases solid rock or larger boulders may be quarried and broken into suitable smaller pieces, and in others the starting point may be a piece of the debitage , a flake removed ...

6. Use-wear analysis - Wikipedia

   en.wikipedia.org/wiki/Use-wear_analysis

   This may require flint-knapping a tool comparable to the artifact under analysis, which can be long process dependent on personal ability, or buying such a tool. Also, the replication of tool use requires comparable source material (for tool creation) as well as access to the material the tool was used on.

7. Solutrean - Wikipedia

   en.wikipedia.org/wiki/Solutrean

   Knapping was done using antler batons, hardwood batons and soft stone hammers. This method permitted the working of delicate slivers of flint to make light projectiles and even elaborate barbed and tanged arrowheads. Large thin spearheads; scrapers with edge not on the side but on the end; flint knives and saws, but all still chipped, not ...

8. Hand axe - Wikipedia

   en.wikipedia.org/wiki/Hand_axe

   Later examples of hand axes are more sophisticated with their use of two layers of knapping (one made with stone knapping and one made with bone knapping). Lastly, a hand axe represents a prototype that can be refined giving rise to more developed, specialised and sophisticated tools such as the tips of various projectiles, knives, adzes and ...
