By understanding the real function of tools found in an archaeological context, we gain privileged access to lifestyles and socio-economic organizations of the past. Tool function can be recreated by analyzing the dynamics of wear and through diagnostic combinations of traces of use (use-wear analysis). The notion of function refers not only to the use of an object, but also to the role it could play in a given socio-economic organization, which is composed of technical reduction sequences. The function of a tool in a chaîne opératoire (“reduction sequence”) is representative of technical choices made in the context of a cultural group, which is acting in a specific physical environment. The search for a function requires not only creating a database of the dynamics of use-wear in a controlled setting, but also carrying out ethnoarchaeological experiments. By studying the physical representation of the chaîne opératoire for processing of hides at three Palaeoeskimo sites in Nunavik, i.e., Pita (KcFr-5), Tivi Paningayak (KcFr-8A), and Tayara (KbFk-7), it became possible to interpret and understand the real function of the selected tool categories and ultimately identify women’s activities in Dorset society and its economy.
