The Prepared-core technique starts by shaping a flint stone core for making blades (reassembled from blades for illustration purposes), Boqer Tachtit, Negev, Israel, circa 40000 BP. The distinctive forms of the flakes were originally thought to indicate a wide-ranging Levallois culture resulting from the expansion of archaic Homo sapiens out of ...
They would have made tools out of chert nodules using a technique called flint knapping which employs the striking of hammer stones and antler billets to remove flakes of chert until the nodules are reduced to bifacial shape. They would have then used smaller antlers to pressure flake these items into spear points, knives, or other tools.
Cores from which blades have been struck are called blade cores and the tools created from single blades are called blade tools. Small examples (under 12 mm) are called microblades and were used in the Mesolithic as elements of composite tools. Blades with one edge blunted by removal of tiny flakes are called backed blade.
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.
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 ...
In contrast to the production of core tools like handaxes, 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 ...
Flake tools could be sharpened by retouch to create scrapers or burins. These tools were either made by flaking off small particles of flint or by breaking off a large piece and using that as a tool itself. These tools were able to be made by this "chipping" away effect due to the natural characteristic of stone.
The Micro-gravette or Gravette micro point is a microlith version of the Gravette point and is a narrow bladelet with an abrupt retouch, which gives it a characteristically sharp edge when compared to other types. The Azilian point links the Magdalenian microlith points with those from the western Epipaleolithic. They can be identified by a ...
