List of the 82 simplified attributes defined on the basis of the sample of studies analysed, with an indication of the usefulness of these attributes for identifying techniques.

The names of studies in black indicate studies on flint or chert; the names of studies in red indicate studies on obsidian or glass; the names of studies in blue indicate studies on all materials (quartzite is excluded because the number of studies is too small). Attributes unanimously considered useful are highlighted in green; attributes unanimously considered non useful are highlighted in orange; attributes with contradictory results are highlighted in blue; attributes whose results seem contradictory due to the grouping of attributes are highlighted in grey.
