I agree Mr. Bud. Mr. Max the Knife, who has sharpened a lot of real-world used knives, reported here some time ago that greater than 95% (I think he said something like 98%) of the well known high-end brand of => HRC 60 knives that he got in for sharpening were chipped.
Most cutlery is in that HRC 54-58 range, and I suspect the reason is because commercial manufactures have learned over the years that is the sweet spot of price/performance and chip resistance. So again, I agree with you Mr. Bud. For me at least, 20% more roll resistance is not worth the extra cost and added propensity to chip with expensive harder steels, not even taking into consideration the increased difficulty when sharpening. I would far rather have a dull blade to sharpen than an ever so slightly less dull chipped one. That said, easier deburring is always welcome.
It’s also interesting to note that the difference between the total roll of HRC 54 and HRC 58 is only 8%. For my use, 8% is statistically insignificant in real-world use.
It will indeed be interesting to see the sharpened after heat treating roll results as that is more real-world. I’ve always wondered how deeply heat treating penetrates the blade.
