One of my bug out kits got wet because I forgot to put contents in garbage bag. My USAF survival knife blade rusted but other stainless steel knife no rust. Used sandpaper to clean most of rust. Sharpened blade with commercial sharpener then whetstone. Now I include sharpener and sandpaper in my kit.
Best all-around knife USAF Survival knife. Only drawbacks..not
Stainless and pommel should be wrapped in paracord or leather cord that could be unwound. Prefer serrated edge
but it doesn’t come with one.
