Thread: Cleaning and restoring of a vintage blade.

I have recently purchased a very nice Boker that I am looking forward to using. It came with a small amount of discoloration on the tang and shoulder where it was in contact with the scales when closed. Is there a way to clean this off without disassembly and great hastle? Not the end of the world if it’s perminant just asking the pros. Lastly, could someone identify the spisific date of this red-injun?
