Looks good, any idea on the age ?
I saw a German documentary on how they resharpen old files again, it was the last company in Germany still doing it, and then it closed as well, mainly due to new files being cheaper.
Quite sad to see a honest trade going out of business.
<EDIT>
Found it again, in German though, but even if you dont understand it, it is interesting to watch and see the process and tools.
