This is being probably overly curious but is there a non destructive method one can use at home to determine (roughly) the HRC of an antique knife?
They seem almost as hard as some of my softer j-knives 58-59. Is this possible???
Those guys new what they were doing and that virgin carbon steel was amazing stuff. too think all of it was eyeballed back in the day, no pyrometers and heat treat ovens. just experience.
