Can pressure flaking be effectively used to repair damaged tools?

Repairing Edges

Pressure flaking is a versatile technique that allows you to subtly alter the edge of a stone tool without compromising its integrity. For damaged tools, focus on repairing the area where the edge has been chipped or worn down. To do this, select a small, thin pressure flaker (about 1/4 inch in width) and use it to carefully tap and shape the edge, gradually refining the shape of the tool.

Refining Edges and Points

When repairing a damaged arrowhead or blade, it’s essential to maintain the original shape and geometry of the tool. To achieve this, use a combination of pressure flaking and percussion to gradually refine the edge and point. Start by using a coarse-grit pressure flaker (about 1/2 inch in width) to remove any large flakes or debris, then switch to a finer-grit flaker (about 1/8 inch in width) to hone the edge and point. Apply gentle, controlled pressure, working in small increments to avoid further damaging the tool.

Safety Considerations

When pressure flaking, it’s essential to wear protective gear, including safety glasses and a dust mask, to prevent injury from flying debris. Work in a well-lit area, and use a magnifying glass or loupe to inspect the tool as you work. To avoid damaging the tool further, always work in small increments, checking your progress frequently and adjusting your technique as needed.
