Brake line flaring tool that actually double flares steel line?

I always have trouble with old used line. I have better luck not trying to "patch" brake line.
I have used the snap on/Imperial Eastman/Mac tools etc one for years and bought a master cool brand hydraulic flarer about 4years ago.
The only thing is that hydraulic one ain't the best when trying to do one in place as it takes up alot of space if you're in tight quarters
