Test Steel Hardness Of Knife Blades - Rockwell Scale
A Rockwell hardness number has many limitations that are overlooked by consumers and even the marketers. Most blades are tested at only one point for hardness, whereas they should have been tested at several different points. Also, Rockwell hardness test only reveals the surface hardness of a material and not its internal hardness.

Generally, knives are described as having an HRC rating of X. HR stands for the Rockwell Scale of Hardness, and the C represents part C of the scale. The Rockwell Scale is used to determine the hardness of a material, and part C specifically refers to steel.
Understanding Rockwell Hardness in Knives at KnifeArt.com
HRc refers to the Rockwell Scale of Hardness, part C. The Rockwell scale is widely used by metallurgists to define just how hard a piece of steel is: the higher the number, the harder the steel. A particular metal's rating is important to the knife maker because a harder steel will hold an edge better than a softer steel.

Understanding Rockwell | AGRussell.com
The important scale for knife steel is Hardness Rockwell Scale C, often shown as HRC, which is further abbreviated to just Rc. How is the test performed? This test is performed by measuring the depth of penetration of a diamond tipped indenter under a large load compared to the penetration made by a preload.
Understanding the Hardness of Metals | Design News
For example, an extremely hard steel might have a hardness of 64 HRC, while a fairly soft steel might have a hardness of 70 HRB. Which scale is best to use? It depends on what you're measuring. The Rockwell C scale is good for measuring hardened steel. Rockwell B is better for softer steel or relatively hard aluminum.

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.

The Sharpest Knife: Rockwell Scale Hardness of Knives
The Rockwell scale is a measurement system used by commercial manufacturers to determine the relative hardness of objects based on the depth of indentation from a heavy object. In other words, they drop a heavy ball or diamond cone onto the steel and measure the size of indentation. For knives they use the C scale in units labeled HRC.
