BTW, regards to the "flattening", I should have said denting: the edge was still kind of sharp, but bent to the sides and rippled into the secondary grind.

Interesting, I would have imagined even the most ductile steels to be kind of brittle at such an high hardness, I was kind of wrong I guess.

Not to state the obvious, but wouldn't 52100 and AEB-L be some of the better steels to use for this? And maybe 1095 full hardness?

You’ll have a tough time defining that hardness for just one steel unless you also fairly narrowly define the use as well. Also I don’t think the torsional toughness test are more important but I do think they’re more repeatable and consistent. Charpy testing higher hardness steels has a lot of scatter in the data.

Maybe hardness only have a minor role in this, as long as the grain size is very small and the carbide content is minimal seems plausible to me that steel will tend to deform rather than crack, which (I think, correct me if I am wrong) usually originate from some kind of inclusion in the steel matrix, like carbide.
If I understand correctly, max hardness 1095 should have most of its carbon content dissolved in the steel matrix, so cementite content should be very low, that could make up a bit for the loss in toughness derived from high hardness.
Just my speculation, I could be totally wrong
