WHAT IS ROCKWELL?

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. When a range is listed, it means that whatever variation occurs in the hardening process will fall within that range. The range should never be greater than two, in a reliably quality controlled setting. The test does little to no damage to the material being tested, and provides important information about the hardness and durability of the steel. I won’t go into the history of the Rockwell scale, as it is easily learned on Wikipedia.
