A biface at the right stage of reduction can be transformed into a finished point, a knife, a scraper, or other tool as the situation demands.

Carrying bifaces rather than only finished tools was a rational strategy for mobile groups covering large territories.

The bone tools in the Anzick assemblage — specifically, cylindrical bone rods that have been found at several Clovis sites — are less well understood in their specific function.

They appear to have been carefully shaped and polished, and they have been interpreted variously as projectile components (foreshafts into which stone points were set), as shaft straighteners, or as other tools whose exact use is not definitively established.

Their presence in the Anzick burial alongside the stone tools suggests they were valued objects that accompanied the stone artifacts as part of a coherent technological assemblage.
