For slip joint pocket knife.


Due to not having access to proper cutlery at work, I have recently gotten in the habit of using my edc pocket knife to cut food while at work. Blades started sticking and I put a few drops of air tool oil in it without any thought towards using it for food as I use the knife for just about anything a guy could need a knife for as well. As a side note, knife started sticking due to pocket lint and surface rust, not food, I always wash/clean the knife very well before and after using it for food.

Anyways, wanting to clean it out and relube it with something safer to consume if I happen to not clean the knife well enough before using it on my lunch. Also, whats good to clean it that would be safe on the stag handle, I was thinking Zep, but not sure.

Air tool oils come in food grade formulas and shouldn't get gummy as they dry. I forget what I have in the shop but just a quick Google search found this Super Lube

Friend always said to make sure you're using food grade oil in your air tools, as it can spray that stuff all over ya. Nail guns in particular like to vent the stuff all over.

Why not use Canola? It was developed as an industrial lubricant originally anyway. Now we eat it. Might as well fry our food in 10w40.

Use mineral oil... Olive oil will turn rancid ...

Yep. FYI, rancid oil is basically varnish. Mineral oil (what I use on cutting boards and butcher block) is a food grade laxative.

Because Canola goes rancid and gums up even faster than olive oil. It's lubricant oil use was limited to steam engines, where the superheated steam could wash off any hardened oil (strangely, in steam service that rancidified oil actually helped stick to surfaces, protecting them from corrosion, making it a positive attribute there).

If you really want to use a plant based lubricant, I'd suggest jojoba oil. That's not going to go rancid on you, and was originally used as a replacement for whale oil for lubricating machine guns.

For my part, I use White Lightning Clean Ride on my pocket knives. The volatile carrier is probably toxic, but evaporates off within minutes, and I doubt the wax left behind is that toxic.

EDIT: Added photo

The lightweight synthetic superlube oil (0w-10) is food grade, and perfect for what you want. I use it to oil the motors in my Snap-on impacts and drills.

Re: olive or canola oil, over time these can destroy some natural and synthetic rubbers and can corrode metals, particularly zinc.

That’s why running biodiesel or veg oil isn’t recommended for all diesel vehicles.

Way before the juice was on trial. He was still a superstar.

Ronnie and OJ are at the urinals in the White House bathroom.

Reagan takes a look over at OJ, and asks him how it got so big.

OJ says rub lard on it every night before bed.

Reagan does it for a month, and heck, it gets shorter.

Runs into OJ soon after, and mentions it isn't working.

OJ asks what he was using. The reply, "Crisco".

OJ laughs and says that's the problem, Crisco is shortening

Ba-dum-tisk. It was way funnier in 5th grade...

That was actually kind of my point for mentioning canola oil. It's ****, it's actually toxic, and food companies are putting it in more products every day. My wife has an allergy to it and gets violently ill after eating anything that has canola. Apparently a lot of people have the same problem and don't even know what causes it.
