Yes Mark, it is unlikely that edges soften due to a momentary overheating; it was just a horseback guess, failing any others.
Whatever causes this, if we only had a clean and quick test to spot the edge that will roll more readily before we put the knife to use or hand it over to the customer.
When we have this test, we can catch what in the sharpening process causes it, and then make a more plausible guess.
Till then it will be from overheating, just because humans are intolerant to uncertainty.
What this device is promising to be, compared to the rope cutting, is like BESS edge sharpness tester compared to CATRA edge longevity tester - or in one word, not the same.
I also put my hopes on it in quick detecting a wire edge without dulling the edge; the knife community think we've solved the wire edge problem, but it has re-emerged in super steels.
