Quick Answer
Combining both pressure and percussion methods can be an efficient way to achieve desired results in flintknapping, as it allows for the removal of large amounts of material and subsequent refinement of the edge. This hybrid approach can be particularly useful for creating arrowheads and blades with complex geometric shapes.
Combining Pressure and Percussion Techniques
When combining pressure and percussion methods, it’s essential to understand the limitations of each technique. Percussion is ideal for removing large amounts of material and creating a rough outline, while pressure flaking is better suited for precision work and fine-tuning the edge. To combine these techniques effectively, start by using percussion to remove a significant portion of the flint, creating a rough shape. Then, switch to pressure flaking to refine the edge and remove small amounts of material.
Pressure Flaking for Refining Edges
When pressure flaking, use a low-angle approach (around 10-20°) and focus on removing small amounts of material at a time. This will help prevent over-flaking and maintain control over the edge. For larger flakes, use a pressure flaker with a flat surface and apply gentle, consistent pressure. For smaller flakes, use a pressure flaker with a pointed tip and apply more precise, controlled pressure.
Hybrid Knife Construction
By combining percussion and pressure flaking techniques, you can create complex geometric shapes and achieve a high level of precision. For example, to create a narrow blade with a sharp edge, start by using percussion to remove the majority of the flint, then switch to pressure flaking to refine the edge and remove small amounts of material. Use a low-angle approach for the pressure flaking, focusing on removing material from the center of the blade outwards. This will help maintain a consistent edge angle and prevent over-flaking.
