Awesome antler percussion and pressure flaking, native AZ obsidian. Spall to point

This video demonstrates the process of transforming an obsidian spall into a finely crafted point using flintknapping techniques. The artisan, Jesse Parra, meticulously works the stone, focusing on thinning, shaping, and refining the edges. Highlights of the process include: Initial Shaping and Edge Preparation (0:01-1:01): Jesse begins by identifying the natural shape of the spall and grinding down thin, fragile edges to prevent collapsing during percussion and pressure flaking. Thinning Flakes and Convexity (1:12-6:50): He uses well-timed thinning flakes to reduce the overall thickness of the obsidian, aiming for a convex and rounded surface. This involves careful angling and striking to remove high spots and create desirable contours. Addressing Imperfections and Enhancing Pattern (7:16-12:51): Jesse tackles issues like hinging flakes and "boo boos" (collapsed edges), demonstrating techniques to correct them. He also focuses on creating a consistent pattern across the surface to eliminate flat, unworked areas. Transition to Pressure Flaking with Antler Tools (15:53-19:00): The video shifts to pressure flaking, highlighting the use of an elk antler tool. Jesse explains how the antler "grabs the edge" effectively for precise flake removal, and demonstrates how to utilize natural platforms on the stone. Refining Edges and Base (19:07-59:22): Further refinement of the edges continues, with attention paid to removing high spots and creating a smooth, even surface. The base of the point is also thinned to prepare for notching. Dealing with Overshots and Tricky Spots (44:01-55:53): Jesse encounters and addresses overshot flakes, explaining how they occur and strategies to mitigate their impact on the point's shape. He also navigates areas of the obsidian that are difficult to flake, possibly due to natural fractures. Final Touches and Notching Preparation (56:39-1:04:14): The video concludes with the point nearing completion, with the base thinned and ready for notching. Jesse emphasizes taking time to plan the notching design to ensure a high-quality finished product.
