Anyone know of a "backyard" method to put the temper back in an EZ-Out?

Not necessarily a shared box, but a tech that relies on tools to make a living. I’ve been doing it for 30 years. And when you need a specialty tool and it fails, you’re usually worse off then when you started. I love easy outs and use them regularly with great success.
sorry i was self projecting... learned early on to keep all the specialty extractors, chasers, thread files, vicks bits, transfer punches, taps and dies under lock and key.

the gen pop knuckle busters are not above the skullduggery of returning busted off easy out to the case!

here's an especially interesting one i had awhile back.
