I worked in wet underground mines for years and found a trick for protecting steel.
With survival knives this trick will work real good .
Get a container and soak your knife in it with a 75% mix if water and 25% Naval Jelly Rust Dissolver for a few days to weeks
This will leave a coating of ferric phosphate, FePO4.over the steel that protects it from further corrosion.
you can then cover the blade with cold gun bluing to blacken it
For survival you do not want a shiny reflective blade anyway.
Also grease your blade by warming it up and dipping it in a good grade grease instead of using oil.
grease lasts longer then oil and does not vaporize over time like some light oils.
