Damascus HRC

[sailfish]

An hour of digging turned up inconclusive. But I've been trying to find the stated HRC of CRK damascus blades in recent years, as they seem to vary with time. The more the better but I'm specifically looking for specs on a 2016 Devin Thomas, 2019 Devin Thomas, and a 2020 Chad Nichols. Thanks in advance to anyone with info.

The cards for the 31s show it as 57-58 so that would cover the 2020 Chad
