A small, narrow stone blade, ranging from less than 5 to 11 mm (0.1–0.4 inches) wide and about 15–45 mm (0.6–1.7 inches) long. They were often made from a conical or wedge-shaped microcore, often punch-struck or pressure flaked. Microblades were often retouched into various forms of microliths. Microblades are found in the Upper Paleolithic industries of Eurasia and in the Upper Paleolithic of Siberia, but are also characteristic of the Mesolithic and later industries of the circumpolar regions. Examples are the Eastern Gravettian, the Dyuktai culture, and the Arctic Small Tool tradition.
