Food Safe Oil for Blade?
« on: August 07, 2014, 06:16:29 PM »
Hi, all -

I just started learning to properly sharpen a knife as one of my 13 Skills for this year.

I have an Ontario Knives SP-1 (see link at the bottom) that's great for camping, or TEOTWAWKI... However, it occasionally shows some light rust spots on the sharpened edge, so I figure I need to keep it oiled. Ordinarily I would just use some 3-in-1, but I sometimes use the knife for food prep.

Is there a good food safe oil that will keep my blade happy and won't gunk up its sheath?

Thanks,
- InquiringMind

I don't know about gunking up the sheath but any oil used for cooking will also protect your knife. Use just enough to keep the surface lightly oiled and you should be good.

Try Froglube, it's "USDA Approved."  It's primarily a lubricant for guns, but also protects steel.  I've had an O-1 Steel blade coated with it for about a year, now, and no discoloration.

Coconut oil,olive oil,vegetable oil...of these I have had the best luck with coconut oil as it is a great oil for consumption and it stays where you put it.

Mineral oil is an option which you can also use on your wood cutting boards.

Unlike food based oils, it won't go rancid.

Thanks for all the great suggestions! I was worried about it going rancid, so mineral oil sounds like a good option.

I've heard mineral oil as well. Someone told me to put it in jumbo straws and melt both sides. That way I have small packets of it in my bag.

I usually use mineral oil but seeing as coconut oil stays put better and I have it on hand, I think I may have to try this.

I lube just about everything with synthetic 5-20. A quart will last you about a lifetime. An empty 5 hour energy bottle is a nice way to carry some spare lube or alcohol stove fuel.

I use very little oil on my knives anyway (maybe a drop on a hunting knife) and if they are going to be used for food prep I wipe them off - but I have a lot of kitchen knives.

Does it taste good?
I don't take a chance with cross contamination as even wood handles and the junction of steel and plastic will hold oil. While I do use the synthetic oil on guns (especially oil with PTFE (Slick 50) mixed in)...I have tasted oil years ago and so I stick to vegetable oil and or coconut oil for food prep knives.

Honestly, 99% of my kitchen knives are german stainless - I don't oil them period.

Most of my outdoor knives are 1095 or D2 or other stain resistant steels - anything that would really have rust issues, I let patina and keep oiled and don't use for food prep.

But I use very little oil anyway - neither my guns nor my knives are dripping with lube.

Mineral oil is the answer to the question - it is also a good laxative, so dual purpose!

Yep, safe for consumption (which would be very minimal) and it is the base for many traditional gun oils.

And I agree, wipe off the blade before use whatever you put on it. :)

Good...I thought I was doing it wrong.

Purchase Laxative Mineral oil from the pharmacy section at most any store. It's cheap and is food grade. Don't worry it won't work as a laxative unless you drink it. That's what I use.

I also use it to treat my wood / bamboo cutting boards.

I've got a carbon steel blade that I use exclusively in the kitchen.  I occasionally use a light, very light coat of oil, but more importantly I developed a patina on it that protects it as long it's not scrubbed too hard.    I cut up a bunch of tomatoes with it and the blade went from "shiny" metal to black, kinda like "blueing" a firearm.  As long as I don't scrub off the patina, it doesn't rust.

Spray it with PAM. I use it on the blades of my carbon steel kitchen knives and the wooden handles also. Convenient and protects the wooden handles.

I often use cold blue to protect my carbon steel knives..

Ballistol is safe (in Europe it is approved for some type of medicinal use...can't remember what) or as suggested Frog Lube.  It is minty though
