Combs
A comb is a tool featuring a linear and discontinuous active section with teeth that are separated at regular or irregular intervals.
There are many secondary alternative types of combs, such as double-pronged tools and multi-toothed combs.

Multi-toothed combs are defined as follows:
 teeth separated at even or uneven intervals;
 profile (curved or straight face);
 tooth morphology (flat, round, oval, dashes or stitches);
 identical or different tooth morphology;
 tooth width;
 tool height.

Changing tool face heights and widths will be explained with the variants. The impression of a comb’s active section is a dotted and lined up multiple impression.

Double-pronged tools are defined as follows:
 tooth morphology (flat, round, oval, dashes or stitches);
 similar or different tooth morphology;
 tooth width;
 tool height.
