Their form suggests that they were hafted. Some examples have small projections or notches at the edge of the working face, suggesting that they were multi-purpose tools. Concave side-scrapers are assumed to have worked like spokeshaves. A number of specialized tools are frequently found on Early Palaeo-Indian sites. These include gravers, beaks, burins and spokeshaves.
Gravers are flake tools with small, sharp projections or 'spurs'.
These are assumed to have been used for perforating soft materials. Larger, heavier flake tools with points are usually referred to as 'beaks'. These were probably used for slotting or hollowing wood or bone.
