The experiment [7] also shows that the Levallois core is an economic optimal strategy of raw material (lithic) usage, which means it can generate longest cutting edge per weight unit of raw material. This result also implies that the mobility of prehistoric people was higher when applying Levallois technology; prehistoric people may explore ...
The concept of the "state of the art" originated at the beginning of the 20th century. [3] The earliest use of the term "state of the art" documented by the Oxford English Dictionary dates back to 1910, from an engineering manual by Henry Harrison Suplee (1856 – after 1943), an engineering graduate (University of Pennsylvania, 1876), titled The Gas Turbine: Progress in the Design and ...
Cutting edge or The Cutting Edge may refer to: The cutting surface of a blade or other cutting tool State of the art , the highest level of development, as of a device, technique, or scientific field
Pressure flaking is a method of trimming the edge of a stone tool by removing small lithic flakes by pressing on the stone with a sharp instrument rather than striking it with a percussor. This method, which often uses punches made from bone or antler tines (or, among modern hobbyists, copper punches or even nails), provides a greater means of ...
The cutting conditions will affect the value of this surface speed for mild steel. Schematically, speed at the workpiece surface can be thought of as the tangential speed at the tool-cutter interface, that is, how fast the material moves past the cutting edge of the tool, although "which surface to focus on" is a topic with several valid ...

However, such a cutting-edge technique was severely criticized by other traditional painters. His style, which was called "Mourou-tai(Blurred style)" (which nowadays exactly depicts his painting's character), meant the lack of energy and vitality sarcastically.
The sabre weapon is for thrusting and cutting with both the cutting edge and the back of the blade [2] (unlike the other modern fencing weapons, the épée and foil, where a touch is scored only using the point of the blade). [2] The informal term sabreur refers to a male fencer who follows the discipline; sabreuse is the female equivalent.
