Understanding Middle Palaeolithic Asymmetric Stone Tool Design and Use

In the Late Middle Palaeolithic, the variability of Neanderthals' lithic technologies in Central and Eastern Europe was complemented by a specific asymmetric tool type - the so called Keilmesser. Due to their morphological characteristics and interpretation as tools in purported long-term use, Keilmesser provide a unique archive for tracing late Neanderthal behavioural features. These may range from understanding tool design, production and dedication, to tool function, use and maintenance; along with aspects of technical innovations and transmission of skills and knowledge.
