I rummaged through my restoration drawer and found this very nice ERN that I can't make up my mind about. I can't date it exactly but my guess is that it is made before 1914. As you can see it seems to be unused and it has got an, in my opinion, very nice etching on both sides of the blade. However the etching has got water stains. What would you do?
- Polish the blade and remove both the stains and the etching.
- Leave the blade as it is.
