Tranchet flake

(重定向自Tranchet)

In archaeology, a tranchet flake is a characteristic type of flake removed by a flintknapper during lithic reduction. Known as one of the major categories in core-trimming flakes, the making of a tranchet flake involves removing a flake parallel to the final intended cutting-edge of the tool which creates a single straight edge as wide as the tool itself. A large flint artifact with a chisel-end, the tranchet flake has a cutting-edge that is sharp and straight. The cutting-edge is unmodified in most cases; sometimes, it is polished for increased durability and/or sharpness.
