Lithic reduction involves the use of a hard hammer percussor, such as a hammerstone, a soft hammer fabricator (made of wood, bone or antler), or a wood or antler punch to detach lithic flakes from a lump of tool stone called a lithic core (also known as the "objective piece"). As flakes are detached in sequence, the original mass of stone is reduced; hence the term for this process. Lithic reduction may be performed in order to obtain sharp flakes, on which a variety of tools can be made, or to rough out a blank for later refinement into a projectile point, knife, or other object. Flakes of regular size that are at least twice as long as they are broad are called blades. Lithic tools produced this way may be bifacial (exhibiting flaking on both sides) or unifacial (exhibiting flaking on one side only).
Cryptocrystalline or amorphous stone such as chert, flint, obsidian, and chalcedony, as well as other fine-grained stone material, such as rhyolite, felsite, and quartzite, were used as a source material for producing stone tools. As these materials lack natural planes of separation, conchoidal fractures occur when they are struck with sufficient force. The propagation of force through the material takes the form of a Hertzian cone that originates from the point of impact and results in the separation of material from the objective piece, usually in the form of a partial cone, commonly known as a lithic flake. This process is predictable, and allows the flintknapper to control and direct the application of force so as to shape the material being worked. Controlled experiments may be performed using glass cores and consistent applied force in order to determine how varying factors affect core reduction.
Levallois Core Reduction: Recurrent Preferential by Dr Chris Clarkson With Commentary
This video describes the process of making several large preferential Levallois flakes from a single core. The video was made for a student project at the University of Queensland.

Lithic Analysis in Archaeology
This video introduces some of the most basic aspects of observing and making measurements on the products of flintknapping, with emphasis on debitage (the flakes removed from a core). It also introduces the chaîne opératoire as a theoretical and conceptual tool for the analysis of lithic and other technologies.

Levallois lithic reduction method tutorial for neurolinguistics experiment
This is a standardised video tutorial for all participants doing a crash course in Mousterian middle palaeolithic stone tool technology for an electroencephalography experiment. This way we can get data on similarities in the neural processing of motor sequence procedures and the neural processing of long-distance syntactical dependencies in language.

Using lithic reduction sites to trace the development of planning & forethought in the humans
Full title: In the Mind of the Maker: Using lithic reduction sites to trace the development of planning and forethought in the human evolutionary past
This paper explores the use of lithic reduction sites and their assemblages as markers of the progression of forethought and planning, in particular mental time travel (MTT), throughout the Palaeolithic. MTT is the ability to move backwards and forwards in time through engagement of episodic and prospective memories. As a field, cognitive archaeology often fails to unite cognitive evolution models, such as MTT, with Palaeolithic research. The significance of forethought and planning is widely discussed but little attention is actually given to their development. A novel approach was trialled in a diachronic pilot study of two lithic case s...

MTT is the ability to move backwards and forwards in time through engagement of episodic and prospective memories. As a field, cognitive archaeology often fails to unite cognitive evolution models, such as MTT, with Palaeolithic research. The significance of forethought and planning is widely discussed but little attention is actually given to their development. A novel approach was trialled in a diachronic pilot study of two lithic case sites. Each site was analysed through its specific chaîne opératoire and each stage was placed in a distinct planning level. The results were then compared to determine if any progression of forethought and planning could be traced. The findings of one case site are presented here. These results, when placed in a wider archaeological and cognitive context show the nuance of cognitive evolution. It is clear when layered with cognitive models; the approach developed is sensitive to cognitive subtleties. By using this approach, we can move away from the traditional ‘has or has not’ understanding of forethought and planning capabilities of toolmaking hominins.
