I just received this ferrule remover tool. The first half of the process worked great: the ferrule [and nut] came right out.
But the nut is really really locked on the thread of the removal tool. I've put enough force on trying to get it off that it has lightly scratched the other end. I'm uncertain if the thread were still whole.
Any hints on how that nut/ferrule can be disengaged from the disengagement tool? (I have three other lines to remove tonight if possible ;)
