Cut marks made by sharp stone or metal tools have a different character.

They tend to be more regular in shape, with flat or slightly curved cross-sections rather than the V-profile of animal tooth marks.

They often run in parallel groups or clusters, reflecting the back-and-forth motion of a blade being drawn across a surface.

They appear on specific parts of bones that are consistent with specific activities: cut marks associated with defleshing appear on the shafts of long bones and around joint surfaces; cut marks associated with brain removal or skull preparation would be expected on the interior surfaces of the cranium.

The distinction matters enormously for interpretation.
