I have a couple of MAC sets, they have saved my you know what so many times, at the drag strip, on the side of the road, work, home, you name it. They have never failed me, the key is to be patient and diligent. They are called rethreader's but I contend they are restorer's you have to make sure you are following whatever is left of the old threads or you can wipe out everything.
I have taken regular taps to the wire wheel to dull them for this but they are usually still too sharp for me, dies can be filed but again are still too sharp IMO.
Seen many a good tech/mechanic strip a savable thread with regular taps.
