Spraying WD-40 on a folder?

WD-40 has trace amounts of muriatic acid in it. Spraying it on your knife will surely cause problems.

But seriously, it'll be fine...
 
WD-40 would help it function more smoothly for a time, but it's not meant to be a long term lubricant. For long term lubrication of the joint, there are much better, longer lasting products, like nano oil, Blue Lube (Benchmade), Tuff Glide, and the are a lot of others. The Modification and Embellishment forum here might have some good ideas.

My hands down favorite lubricant oil is Rem oil. Made for guns but works wonders on knives and multitools. If anybody here feels that's a bad idea please tell me. I have long known that WD-40 is bad for knives but not sure why. Looks like the fella above me knows why
 
I can't stand Rem oil or WD on my firearms and or tools. I, personally, find them inferior to other products out on the market. I prefer Frog Lube in most all cases. In other cases I use LPS Labs products. Look up those two and order some products. Wait till you see the difference. I bet you will likely retire the Rem Oil & WD and give it away. Or use it as a fire starter or for trash and junk projects.

EDIT: FWIW: if you prep food with your folder, Frog Lube and LPS both have food grade lubricants. I find that very important to me.

Really? Do ya'll know what "WD40" actually stands for?

WD 40 stands for "water dry 40th composititon". So, where did WD40 come from? A group of scientist's were tasked with finding a product that would keep corrosion from forming on Nuclear warheads. Nuclear warheads that were sitting in a moist condition in underground silo's. And it took them 40 different combinations before them came up with what became WD40. Hence Water Dry 40.

As I grew up during the early Seventies, I was introduced to the Skeet Shooting community. And the Quail and Dove hunting community. I promise you. These shooters, shooting 100's of rounds a day. Some shooting shotguns that cost Hundreds of times more than most knives, used WD40 to wipe down their guns before putting them in their cases. I saw this thousands of times. I've wiped down my guns, AR-15's, Semi-auto shotguns, pump guns, bolt guns, pistols, revolvers....I think that covers most. And I have exactly 0 problems with rust. And I live in Central Alabama where humidity is very high.

As far as "traces of Muriatic acid". OK then. That's because Nuclear Warheads do better being protected with a lubricant containing Muriatic acid? I guess. NOT.

I don't use WD40 as a lube. It makes a nice thin lube. I use it as a protectant. I use Wal-Mart 10w30 synthetic as a lube. How much lubrication do ya'll think a knife needs exactly?
 
Fishing rod reel oil is all I've been using lately, and some gun oil on my carbon blades for a light coating to prevent corrosion.
 
It's actually "Water Displacing #40.
WD 40 contains no traces of muriatic acid. Where do you guys get this stuff?:rolleyes:
The lubricant in WD 40 is mineral oil-just like the lubricant in 99% of the other oils on the market.
I have used WD40 every day in my professional knife restoration shop for years.

"Water Displacement, Formula #40".

A group of scientist's were tasked with finding a product that would keep corrosion from forming on Nuclear warheads. Nuclear warheads that were sitting in a moist condition in underground silo's.

Not used on nuclear warheads, but used on the thin-skinned fuel tanks of Atlas ICBM's.

When I talked about it not being a long-term lubricant, I was speaking from my own experience, using WD-40 as lubricant. It works pretty well, but seems to evaporate much more quickly than other lubricants available today. WD-40 as a rust-preventive coating works wonderfully. Half of my yard & pruning tools in the garage are coated with it for the winter.

I wouldn't use it as a lubricant for a folders action, but for cleaning folders they are great. You can spray them down to clean the crud out then wipe them down and put a drop of oil in the pivot action.

I think I also heard that CRK sprays down their titanium grips with WD-40 before shipping them out. Gives them a fresh gleam.
 
The military does not allow WD-40 to be used on small arms.
Combined with powder residue if forms a vey tough varnish type of coating which will cause jamming malfunctions.
In the Vietnam era it was a real problem.

Research tests of rust/corrosion comparisons with WD-40, not the best.

As a cleaner penetrating oil, fine,,,, much better lubricants are available today.

+1.

WD-40 is just mineral oil plus mineral spirits. The latter works as a mild solvent, then evaporates leaving behind the mineral oil. Btw, Leatherman's website recommends WD-40.

FWIW, Johnson's Baby oil is also mineral oil plus fragrance.

WD-40 fine, as long you are okay with mineral oil.

Other fine contenders:

- Breakfree CLP. I spray this stuff on anything that moves. Love it.
- Ballistol. Stinky but good. Spray it on leather and wood too.
- Boeshield T-9 (solvent plus waxy compound; the solvent evaporates, leaving a waxy coating that endures. Made by Boeing for aircraft. Good stuff).

Just my opinion.
 
Boeshield is awesome stuff for steel that gets around salty water/humid air.

I'm using Fireclean, and I know some other folks are fans of Froglube.
 
My new orange Delica 4 was looking a little dirty. Some hot water and WD-40 cleaned the FRN scales back to their original glow.

I use a drop or two of Tuff Glide for lubricant at the pivot.
