So how much harder is 60 HRC than 59 HRC? BladeForums

Jun 19, 2012 · I see rockwell hardness numbers thrown around a lot, but I've never really seen anything that clearly defines how much harder 60 HRC is than 59 HRC. I looked around at the way the HR numbers are actually calculated, and found that in terms of measuring the depressions and everything that are actually used to get the hardness value, there's only
