Size: Largest: approximately 15 cm long (Ballenger 2014:3); typically resharpened until exhausted. Average stem length: 12.5 mm; average max. width: 18.1 mm; average max. thickness: 4.7 mm (Lyndon 2005:Table 10); Average length: 25 mm; average base width: 20.9 mm; average max. thickness: 5.4 mm (Loendorf and Rice 2004:Table 9).
Shape: Triangular with wide necks and concave bases with rounded ears that are wider than the point blade.
Cross-section: Thick biconvex to thin and flat.
Base: Deeply concave, eared.
Flaking: Percussion and pressure; random.
