Peripheral blood cells were stained with HLA-A2.1 tetramers containing the tyrosinase368–376 peptide followed by staining with a panel of lineage antibodies, as described in
Blades and blade fragments seem to have been especially used for longitudinal motions, mainly on plant material (7/12). Flake and flake fragments are used in different motions on
This shape also occurs in the combination artefacts (see below). The shape is the result of intensive use in a repetitive abrasive motion, carried out from different angles. In
