Heat treat Recommendations by Nick and to be done by Roger
This billet is a 1084/15N20 mix.

It should be normalized after grinding 3 times (heat to 1400F and cool to black between heats).
Then the blade can be austenitized at 1450-1500F and quenched.
The lower the aust. temperature you go with, the longer I'd soak it.
If you want to get it fully hard, I recommend soaking at 1450F for 5-10 minutes
(after the blade has equalized with the heat source) and then quenching.

Your oil warmed up to the 120-160F range will work nicely.
Typically, I temper at 400F, but sometimes go up or down a touch depending on the knife
