A flint blade
In
archaeology a 'blade' is a type of
stone tool created by striking a long narrow
flake from a stone
core.
Blades are defined as being flakes that are at least twice as long as they are wide and that have parallel or subparallel sides and at least two ridges on the dorsal (outer) side. They became the favoured technology of the
Upper Palaeolithic era, although they are occasionally found in earlier periods. A soft punch or
hammerstone is necessary in creating a blade and their long sharp edges made them useful for a variety of purposes. They were often worked to create
scrapers or
burins
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
bladelets 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.
