Another tutorial from the Mad Chef. A subject that often goes pretty much overlooked is the quality of knives, whether they be for hunting, camping, or in the kitchen. Many folks opt for the more expensive the better, but that is not always so.
I have owned many knives in my life, mostly in the hunting, butchering, kitchen, and pocketknives. One category that often goes overlooked when selecting a knife is the HRC. The Rockwell scale C, also known as HRC, is a method used to measure the hardness of a knife. A higher hardness level means the knife can be sharper and maintain its edge for extended periods. Typically, kitchen knives have a hardness range of 50-65+ HRC, with most consumer knives falling between 52-62 HRC. It is essential to consider the trade-offs when choosing a knife. Knives with a higher HRC rating can be more brittle and prone to chipping or breaking as well as harder to sharpen if not used properly. On the other hand, knives with a lower HRC rating may not chip or break as easily but will lose their edge more quickly but will be easier to sharpen.
Rockwell Hardness
52-54 HRC
Cheap, needs sharpening
54-56 HRC
Sharpen a few times a day for professional use. Suitable for home cooks.
56-58 HRC
Easy to sharpen, used in professional kitchens
58-60 HRC
High quality, stays sharp longer, harder to sharpen
60-62 HRC
Remain sharp for a long time, but have more risk of becoming brittle
63-66 HRC
Needs cleaning after each use, prone to breaking and becoming brittle
