Ya, I hear you. I cryo everything. But, I still wouldn't do it without following up with a temper. Look at it like this: the effect of cryo is to continue the process started by the quench. The quench causes stress in the steel, that stress is removed by tempering. Now, as you said, some steels are not as affected by this as others but that isn't to say they are not affected at all, i.e., cryo causes stress. Admittedly, that should be considerably less stress than quenching but still stress nonetheless. Just because Dtec didn't have a blade that failed doesn't mean that no blade will fail. In the final analysis, as unlikely as a failure of this type might be for some steels the insurance against failure is cheap and easy - simply do a temper cycle and remove even the possibility of having an issue ...
