The Rockwell Hardness Scale is a standardized measurement used to determine the hardness of materials, including metals and alloys. By assessing the depth of indentation made by a specific indenter under a fixed load, it quantifies the resistance of the material to deformation. This scale is crucial in industries where material durability and performance are paramount, such as in the crafting of high-quality knives, where it helps ensure that each blade meets exacting standards for edge retention, durability, and overall functionality.
