That's not a problem. Having the oil heated to 400 is the problem.It’s not the oil at 400f that should scare you. It’s the steel at 1500f going into the oil.

Oh, I wasn't suggesting quenching into oil pre heated that high...Quenching into oil at 400 is worse than just heating oil to 400 and putting a room temp blade in it, IMO.
Once you've raised it so close to the flash point, quenching a 1500f blade just sounds like a disaster that makes salt pots sound like safety devices.
Now, if there are marquenching oils out there with super high flash points like Larrin suggested, OK.

This is true. The problem is that you are holding a oil near its flash point and simultaneously quenching an object far above it's flashpoint. Frying is safer because while you are near the flashpoint, you are not introducing anything to the oil that will bring it above said flash point. Also fryers are designed not to spill on the operator.I know, there's 2 conversations going on. Oil can be dangerous either way. Though it's likely easier to find a safe way for heating and holding the proper high flash point oil to 400f for normal tempering than for marquenching. I didn't even think there was such an oil out there. Or like Joe said, industrial controls.
Either way I'll save hot oil for my turkey personally. Well away from my buildings.
