The first group 'morphology' contains all the attributes and measurements related to the morphology both of the artefact and of the edge. These include the following:
length, width, thickness and mass (weight) of the artefact
edge angle, edge length, edge thickness
edge profile. The profile of the edge was measured following Grace (1989) and placed in one of three groups: concave (<-0.1), straight (-0.1–+0.1), convex (>0.1).
The shape of an artefact was initially obtained through the ratio length/width following Grace (1989) and were grouped in the following way: very long (>3); long (1.2–3); square (0.8–1.2); short (0.3–0.8); very short (<0.3).
The shape (Z) (Shiel ratio) was then recalculated as Z=I2/S. This gives a range from >1, which is planar, ~1 is cubic and <1 is columnar.
The second group contains all the macroscopic observations, obtained at 10x magnifications, related to edge damage following Grace (1989). These include:
dorsal and ventral macro fractures (absent; <5 per 10mm; >5 per 10mm)
dorsal and ventral macro fracture type (flakes, snaps, steps, flakes and snaps, flakes and steps, flakes and snaps and steps, flute, absent)
edge rounding
The third group contains the results of the microscopic observations following Grace (1989). These were obtained at 200x magnifications. This group includes the following observations;
dorsal and ventral micro fractures (as macro)
dorsal and ventral micro fracture type (as macro)
dorsal and ventral micro rounding (absent, heavy, light)
dorsal and ventral microtopography (flat; undulating; ridged)
dorsal and ventral polish distribution (continuous; intermittent; absent)
dorsal and ventral polish distribution type (away from the edge; gapped; edge only even; edge only asymmetric; differential; absent)
dorsal and ventral polish invasiveness (edge only; <0.5D; >0.5D; absent)
dorsal and ventral micro linear features (parallel; perpendicular; angled; parallel and perpendicular; parallel and angled; perpendicular and angled; absent)
dorsal and ventral microstriations (parallel; perpendicular; angled; parallel and perpendicular; parallel and angled; perpendicular and angled; absent)
dorsal and ventral polish development. [A (individual pockets); A+ (large unconnected individual pockets); B (linked pockets); B+ (greater linkage between pockets); C (all over polish); D (linear)]
The final group contains all the ethnographic information. This includes the following;
User (12 possibilities)
Edge angle unused (as measured in the field before use)
