Carbon steel knives will always develop a patina with use, this is normal.kennethsime wrote: ↑Sat Dec 03, 2022 12:43 pmI'm not 100% opposed to this. I guess my question is: will this turn into destructive corrosion, or is it just that - patina?
You should take it as a sign of "proof of use" that it is not being a safe queen.
You just have keep them dry to avoid reddish brown rust, they will naturally patina and stain with cutting. You only clean the reddish brown rust because it is more destructive just use Bar Keepers Friend; there is no elbow grease with that stuff.
Again carbon steel will stain this is normal, just like carbon steel cookware darkens with use over time and does not stay shiny.
