As unifacial stone tools get thicker and rounder (size-adjusted thickness, Tsa, increases) the % of unifaces with a spur does not significantly increase (ρ = 0.600, p = 0.208).

This result does not support the notion that spurs were created incidentally or accidentally via resharpening. In this instance, the Tsa range of each group was equal.
