| We now have a thin biface with nice convexity which could be finished with pressure flaking in a minimal amount of time. | All the primary, secondary, and tertiary flakes from the reduction process to this point. A few of the pressure flakes escaped on me, but for the most part this is the complete debitage pile from the reduction process. These would all have been used as tools or as blanks for points, scrapers, etc. |

| An obsidian biface showing a face that was thinned with 3 overshot flakes. Notice how the middle overshot flake initiates from the bulb of percussion and widens out into a thin and wide flake that travels the full width of the piece. The bottom left corner shows some pressure flakes just starting to regularize the edge. | The opposing face showing more pressure flaking which has started to obliterate the percussion overshot flake scars. The piece is extremely thin at this point. |
