In the early Holocene archaeological record in Northwest Santa Cruz province, a peculiar modality of manufacture of unifacial lithic artefacts was identified. In its reduction sequence, the flake blanks were flaked by detaching totally or partially covering flakes and then finished by scalar retouches of about 10 mm. In order to deepen in the knowledge of its manufacture, replicative experiments, and diacritic analysis were performed on the experimental and archaeological specimens. The obtained results show that the totally or partially covering flake-scars correspond to a preconceived and deliberate action tending to shape the flake blank and are not accidental or result from the resharpening. In this way, the research reinforced that this way of making artefacts may correspond to a technical style shared by the early Holocene occupations in central-southern Patagonia.
