I think the point is that in inexperienced hands both either file or die alone can do a lot of damage. Yes I am sure in experienced hands a file/chaser alone will get a thread functional again ( I have done so myself ) however there is also a risk of removing too much metal and significantly weakening the thread. A die on the other hand, if you can get it started correctly, will only remove the flattened portions of the original thread (and would be my preference) however get it wrong with a die and you are even worse off then you were at the start. Which ever method you choose take care as is there is a lot of load imposed on this thread to remove a tight hub.
