Working on the 90 year old razor that was given to me with heavy rust. I’ve sanded it down to this pitting. Any suggestions? Will I ever get through the pitting without wearing out the blade?
It looks to me like celluloid rot caused by the natural off-gassing of old celluloid. This is common on some brands of vintage razors. I'm not saying that the razor isn't salvageable as I've been able to save some razors that looked similar. However, you will want to replace those scales and avoid storing that razor long-term around other razors as it is quite contagious.
