Hello gents, I found a NOS Carl Frederich ERN razor couple weeks ago. I was planing to buy this beauty since then and did some research. Although, I haven't found any date, I knew ERN was a good company and they made very good razors back in the days.
It has two small rusty spots and some dirt. Can you give me any advice how to clean it without damage the etching.
By the way factory edge is not good but not bad, how can I touch-up the bevel? Shall I dull the blade on the glass or just touch-up on the 1k and go up?
Thanks in advance.
