When looking at knives you will often see a number in the specs with RC after it. This number represents the Rockwell Rating. The Rockwell rating is a scale that is used to measure the hardness of a material. An example is stainless steel AUS-8, which usually 57-59 Rc. The Rockwell hardness test is the industry standard for knives.

The hardness is inversely proportional to the depth of penetration. There are many Rockwell hardness scales, depending on the type of indenter and load used. For example, the Rockwell C scale uses a cone-shaped, diamond-tipped indenter with a 150-kg load. The Rockwell B scale uses a 1/16-inch diameter ball indenter with a 100-kg load.
The Brinell and Rockwell B scales are generally used to measure hardness in stainless steel. (Note: the Rockwell A scale is used for softer materials; Rockwell C for the hardest materials) Actual hardness testing consists of a precision tip (or ball) that enters the material surface under the force of a specific load.
