Incisor tools were frequently used where fine engraving and delicate carving was needed -- the natural cutting edge of the tooth provides a fine, sharp cutting edge. These tools were usually 'hafted', or fit into a handle, that allowed the user to better grip the tool. Wooden handles do not preserve well in wet, acidic soils, so usually only the tooth is left to be discovered by archaeologists.

In some cases, detailed inspection of incisor tools shows abrasions on the cutting adge from resharpening. Use wear and various kinds of edge damage can be used as indicators of what kinds of materials were being worked with the tool.

This artifact is from the Belcara site, on British Columbia's coast, and dates to between 750 and 200 years ago.
