How I Protect My Knives From Rust Sharp Works

Rust is a natural and inevitable thing that forms on high carbon steel knives. There are ways to prevent it, or at least slow down the process. Simply, a knife needs a coating to prevent air and moisture from interacting with the metal. The best rust prevention is to force patina your knife, but will ruin the shine of your blade. A coating can also be paint, wax, oil, etc. The easiest coating to use is oil (any type of oil). Apply a thin layer on your knife and it will protect it for a couple of weeks, or until the oil evaporates off and dries out.

I found that the best protection coating comes from petroleum jelly since it does not dry out as quickly and it forms a thicker layer over the knife. In this video, I show that moisture can be trapped on your knife when it is dirty or without a coating. With petroleum jelly, the water sheds right off and whatever water stays on the blade won't affect the knife because it is resting on top of the petroleum jelly.

I use this on my knives when I know that I will not be using the knife for a while (a month +). This is because once you use the knife, with oil or petroleum jelly on it, the coating will wipe off and need reapplying. I usually use oil on the blades that I use more frequently and petroleum jelly on the blades that I keep lying around inactive.

This is best for collectable blades, show-pieces, or any knife that you want to keep in pristine condition.
