I own a few 1095 carbon knives and like to keep them well oiled to prevent rusting. I keep lube in the pouch on their sheaths but am trying to think of a way to make due without. Does anyone know of sources for an oil or rust preventative in the wild? I've heard you can use oil from the side of of your nose(not snot) but I have dry skin and in certain climates this may not be reliable. I was thinking maybe animal fat or possibly oil from a plant. Any ideas?
