When making small mini-prybars/keychain tools how do you HT?

[Steelhog]

Hey all - I have decided to make use of some of my steel cutoffs that are too small for knives and try to make some keychain prybars/screwdriver tools. For anyone that has also done this - how would you heat treat something for this intended purpose if at all?

I have a steel cup for small stuff. Quench it all at once dunked in oil. Remove one by one from cup, return the oil and temper.

Depending on the steel on how to h/t but would shoot for a Rc in the mid to low 50's

I did a batch of key chain bottle openers/slotted screwdrivers and put them all on a big ring of mild steel. I took the ring out of the oven and quenched the whole lot at one time. I shook it all around and up and down rapidly to get a good cooling rate. Worked fine.
