Well, my deep fryer fried, I don't understand why, it was only 10+ years old.
I now have a double walled quench tank with a lid so I heated a rr spike in the forge, chucked it in the oil to warm it and hardened 2 blades. I had to use the wife's toaster oven to temper them.
i was really looking forward to experimenting with tempering in the deep fryer.
