Burin: A chisel-like implement derived from a flake or blade; the modification of other implements by using the burin technique to remove the edges parallel to their long axis and/or transversely or obliquely. Generally forms a right angle edge on one or both margins. The specialized flake removed as a result of the burin break is called a burin blade or burin spall" (Crabtree 1982, 27).

The negative scar produced by the removal of a burin spall is calleda burin facet. A burin is a tool which can take many forms, but all are made by the burin blow technique. This has been defined as the action of making the ´sides´ or facets of a burin.



A burin spall can be defined as "the part of a flake, blade, or bladelet detached by burin blow technique" (Tixier 1974, 9).
