Quick Answer
To maintain sharpness on stone tools, regular maintenance through touch-ups and flaking is essential. This can be achieved through the use of a pressure flaker, a fine-grit sanding stone, and a steady hand. Maintenance should occur after each use to prevent dulling.
Sharpening Techniques
When sharpening stone tools, it’s essential to use a pressure flaker to re-sharpen the edges. Hold the tool at a 20-30 degree angle, with the bevel side facing you. Apply gentle pressure, using a soft mallet or your thumb, to create small, controlled flakes. This technique should be repeated several times, checking the edge for sharpness after each flake.
Flaking and Maintenance
To prevent dulling, maintain sharp stone tools by touching up the edges after each use. This involves removing any debris or residue that may have accumulated on the edge, and then using a pressure flaker to re-sharpen the tool. Aim for 2-3 touch-ups per tool per month, depending on usage. For high-usage tools, such as arrowheads, consider daily maintenance.
Tool Maintenance and Storage
To maintain sharp stone tools, proper storage and handling are crucial. Store tools in a dry, protected area, such as a wooden case or a sealed container. Handle tools by the handle or a stable part of the tool, avoiding contact with the edge. Regular cleaning and lubrication can also help extend the life of the tool. For particularly sharp tools, consider storing them in a padded compartment or a separate, secure container.
