  3. Understanding Rockwell Hardness in Knives at KnifeArt.com

    Understanding Rockwell Hardness in Knives. There are several different Rockwell scales; each one is used for a different material. Scale C is specifically used for rating the steel used in knives. The highest RC rating is not necessarily the best A harder steel will generally hold an edge better than a

  4. Rockwell scale - Wikipedia

    The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measuring the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). There are different scales, denoted by a single letter, that use different loads or indenters.Some results are removed in response to a notice of local law requirement.
