What type of stone produces the best noise for attracting attention when?

Choosing the Right Stone for Noise Production

When selecting a stone for knapping, it’s essential to consider its ability to produce a loud, sharp crack. This is often necessary for signaling or attracting attention in survival situations. Stones with high silica content and a dense, fine-grained structure tend to produce the best results. In particular, Arkansas Novaculite is renowned for its loud, sharp crack when struck.

Techniques for Maximizing Noise Production

To maximize noise production when knapping, it’s crucial to use the correct striking technique. Aim for a direct, perpendicular strike with a hard hammerstone, using a force of around 5-7 pounds per square inch (PSI). This will help generate a loud, sharp crack. Additionally, use a sharp, well-prepared edge on the knapping stone to increase the likelihood of a clean, loud fracture.

Pressure Flaking for Enhanced Noise Production

Pressure flaking is a technique used to remove small flakes from a knapping stone. When performed correctly, it can help create a sharp, loud edge on the stone. To apply pressure flaking for enhanced noise production, use a small, sharp pressure flaker to remove small flakes from the edge of the stone. This will help create a sharp, clean edge that will produce a louder crack when struck.
