Great advice Utopian, thank you! The bow razor looks as if is serrated, so yes, it's really rough. Do you have a good resource for blade restoration that I can refer to? I was thinking of using a lot of elbow grease and 1000 grit wet/dry sandpaper to get started...but not sure if that's the right direction to go. I do intend to shave with a couple of them, although I only recently switched to a safety razor...straight razors are my next step.
