The objective piece, or the rock being reduced by the removal of flakes, is known as a core. [ 1 ] : 254, 258 Once the proper tool stone has been selected, a percussor or pressure flaker (e.g., an antler tine ) is used to direct a sharp blow, or apply sufficient force, respectively, to the surface of the stone, often on the edge of the piece.
In archaeology a chopper core is a suggested type of stone tool created by using a lithic core as a chopper following the removal of flakes from that core. They may be a very crude form of early handaxe although they are not bifacially-worked and there is debate as to whether chopper cores were ever used as tools or simply discarded after the desired flakes were 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 ...
In archaeology, a blade is a type of stone tool created by striking a long narrow flake from a stone core. This process of reducing the stone and producing the blades is called lithic reduction . Archaeologists use this process of flintknapping to analyze blades and observe their technological uses for historical purposes.
In archaeology, a lithic core is a distinctive artifact that results from the practice of lithic reduction. [ 1 ] [ 2 ] In this sense, a core is the scarred nucleus resulting from the detachment of one or more flakes from a lump of source material or tool stone , usually by using a hard hammer precursor such as a hammerstone .
The HSS core drills with Hard Coating are core drills with a coating on them, generally TiN Coating. This makes the core drills more resistant to heat, longer tool life, and even removal of chips. These core drills are gaining a lot of popularity over the Standard HSS core drills these days.
