Water, Oil, or Wood? The Secrets of Metal Hardening
The quenching process is a crucial stage in toolmaking, determining the future hardness and durability of the metal. Rapidly cooling red-hot steel in water makes it incredibly strong, while using oil or natural mediums like earth or wood helps maintain its elasticity and prevent cracking. Choosing the right cooling method transforms an ordinary blank into a reliable, high-quality tool.
