Recommendation? Rust Inhibitor with Best Durability?

Sorry if this is a dumb question, but I was just wondering if I could find tests anywhere comparing how "durable" a rust inhibitor was. Obviously there are tons and tons of test of applying X oil or wax or whatever to bare steel and then having them sit in the rain or something to show rust prevention. The problem is, it's kind of hard to take these results in a vacuum because maybe Y oil was the best at preventing rust, but would come off as soon as you even touched the metal, making the test useless. If there aren't any comprehensive tests, your personal experience with whatever you use would be helpful as well. Thanks
 
I find that fluid film, Krown, and wd-40 “specialist” rust inhibitor work the best. None of these are food grade though. In my experience they are effective for 6-8 months without re applying. If using them on cutting tools a more frequent application my be necessary.
 
Do a search on Youtube. Someone made a two-part video testing about 20 different brands of rust preventatives side by side and hour by hour. Brilliant piece of experimentation! He used identical plates of bare steel, stuck side by side in a frame so you can see the results for yourself.

The only "rust inhibitor" that will do what you want is one that hardens to stay in place-like paint.
 
Many people really like to use Ren-Wax as it works well and doesn't react adversely with other materials on a knife and protects well. Ive seen brass on a Buck 110 look like new years later and a patina never forms on carbon blades. It must be mentioned the examples I speak of were never carried but Id imagine to achieve a level of protection desirable on an EDC one would only have to apply more often.

Personally Ive used regular old Johnson Wax to great effect on knife blades, vintage bayonets and high lustre vintage S&W revolvers and have never experienced a lower level of protection.

Waxing the blades protect very well, what I do is, I force a dark boiling vinegar patina on the blade then wax it with hot food grade paraffin and buff it smooth. This has given the best simple diy rust protection I have ever tried on carbon steel and the patina becomes beautiful with use. The need to re-apply wax is far less often then simple oiling witch does not last even a day and it add the bonus to render your blade much easier to clean.
