The Rockwell hardness of any knife blade is the best indication of edge retention and sharpening ease.
In many of these columns you will see the phrase “Rockwell Hardness” when commenting on actual blade hardness. Invented by metallurgist Stanley P. Rockwell in 1919, the Rockwell Testing Instrument is able to determine the hardness of a wide range of materials, as well as many non-metallic materials. The instrument typically uses a cone-shaped diamond applied under pressure to penetrate the object tested. When a knife blade is tested, it is secured in a fixture and the diamond impressed into the blade under pressure. Initially, the first application of the diamond is used to establish a zero-reference point. Then, the diamond is applied Continue reading Hard As A Rockwell
