![]() ![]() ![]() Knapping is the shaping of flint, chert, obsidian, or other conchoidal fracturing stones through the process of lithic reduction to manufacture stone tools. Unlike conventional knives, which are forged and ground, obsidian knives are created through a process known as knapping. How Obsidian Blades Are MadeĬreating obsidian blades is a meticulous and delicate process that dates back to prehistoric times. The sharpness and precision of obsidian blades have led to their use in various applications, from early human tools to modern surgical instruments.Īs we explore further, we’ll understand more about how obsidian blades are made and their applications, especially in the medical field where their ultra-sharp edges are put to use. This process leads to incredibly sharp edges that are just a few molecules thick, significantly sharper than a typical steel knife. When obsidian breaks, it fractures with a distinct conchoidal or shell-like pattern. The properties that make obsidian suitable for blade crafting lie in its unique formation process. This glassy, lustrous mineral is found worldwide and has been used in various tools, including blades, due to its razor-sharp edges. It’s created when felsic lava extruded from a volcano cools rapidly without crystal growth. Obsidian is a naturally occurring volcanic glass formed as an extrusive igneous rock. 9 References Understanding Obsidian Blades ![]()
