How do i prevent rust?

[JJ_Colt45]

Rem Oil will work ... if you arent worried about food contact any decent 3in one oil would work ... there are some options that dont have a strong oder ... that would be the only thing Id check out Rem Oil isnt terrible like WD40 or some others

Hi,

I live near the ocean and I recently got a D2 steel knife.l for the first time. I hear it is rust prone. Preventing rust is very simple since I have gun oils, but all seems very toxic (some say fatal if ingested)

I want to use it for food prep.

What is the best oil/method to keep it from rusting, but also not worry about eating food prepped with it?

If anyone has a cheap method, it would be great, then i can maintain them all the knives same way. Someone suggested Nano oil, but it seems too expensive to slather on every knife I have, after every use... someone also suggested Frog Lube, but then im told that is just coconut oil....which i have plenty of.

If anyone has a suggestion, i would appreciate it very much.

Thank you

Seems like lots of solid advice. I’ll just add my two cents: just about anything derived from petroleum has always worked well for me. Some petroleum-based protectants will do their job for week, others for a few minutes. However, I found that irritating, and I wanted something foodsafe, so Ive started using a mixture of beeswax and mineral oil, and I’m pretty happy with it.

Melt the beeswax, dump in a little mineral oil, make sure its mixed well, let it cool, cram the mixture into a container, good to go.

I never measure, but I’d say I use about 2 parts mineral oil, 1 part beeswax (melted, as a liquid). I adjust the mixture depending on how I’ll be using my knife. A fairly thick paste for storing a blade, very thinned out for daily use. A little beeswax goes a long LONG way.

I liked the idea of mineral oil (food safe and all), but it would separate almost as soon as I put it on the steel, so it was kinda pointless. Beeswax alone would, obviously, be a huge pain in the butt, like trying to coat a knife with a crayon. Someone suggested mixing the two.....works darn well.

I’d say I like pure lanolin almost as much. In fact, just for ease of use, I’d prefer to just use lanolin. But, with some people having a severe allergy to lanolin, I didn’t want to be way out in the wilderness and risk causing someone to go into anaphylactic shock.

So far, so good. I’m pretty anal retentive about caring for my gear. But, my knives see a lot of use, and I don’t baby them. They come in contact with water, fish guts, blood from field dressing, etc. I use it on my stainless steel, and carbon knives. Zero problems, 100 % happy happy happy!

A couple options on top of any patina or coating.

Food grade mineral oil is ok.
Pure beeswax or carnauba, or a mix is good. Cutting board wax is a mix of those and mineral oil. The waxes are less messy than oil.
Food grade silicone is good for blades and not messy either.

Hot food grade paraffin bath, has always protected my carbon steel patina beautifully and the protection last way longer than any oil I tried. I never waxed nor oiled a D2 blade until it start rusting and that did not happen because, first it is not that prone to rusting at all and second If there is no trace of corrosion on the blade, oiling D2 is like putting water on the back of a duck it wont stick there a minute. I just clean them with soapy water. D2 will darken with time especially if you cut meat with it. But the surface of the blade will remain rust free if you keep it clean and store it dry.

Edci was re introduced to the market recently.. Some vids on the topic.

Some great advice so far, especially like the idea of natural waxes where food prep is a concern. My experience of Oceans is that literally everything rusts. Even things that don’t rust. This may not be food safe so may not be for you in this particular application but I know the Tuff Glide people make a “marine tuff cloth” which they purport to be used by special forces for gun (and I guess knife but can’t remember) protection. It seems specifically aimed at ocean type applications. I have used it and it dries well and according to them molecularly bonds with the metal but I haven’t tried it in the setting it was designed for and don’t know whether it would come off in food prep. What I do know is it works great at repelling greasy finger marks or dust which just wipe straight off and I don’t worry about getting my M4 blades wet. I found in the past that even my perspiration or oily thumb would “patina” and tarnish M4 around the Spydie hole and it doesn’t happen since I wiped this product on it. Oh and if cost is a concern the cloth lasts for ages if kept in a sealed container but they sell a top up bottle for when the cloth finally dries out (or to just spray directly) that will probably have the cloth wear out before I run out of liquid.
