I found this in another thread. It really gave me some clarity.



Dear Members,

I was looking through the forums and happen to come across this post. I just finished replying to an e-mail from a customer regarding this subject. I thought it might be relevant here so I've included it below.

Best Regards,

Ernest Emerson



Dear xxxxxxxxxx,

As with everything we do, it is purpose driven. Although many not knowing the history of Emerson Knives think that we are just another Knife Company, the roots of this company are buried deeply in the history of the Naval Special Warfare community.

Per the requirements set to us by NAVSPECWAR, all of our materials were dictated to us by the environment they were to be used in. Since SEAL operational duties require exposure to marine environments, all of the materials chosen for our knives had to both function and not degrade upon exposure to salt water.

You may note that we were also the first company to use Nylatron washer bearings for that same reason. Although they may be smoother, bronze or brass washers degrade and oxidize almost immediately upon exposure to salt water. Just another reason that Emerson Knives are different from the other knife companies that just claim to be "hard core."

The lubricant that we use is a graphite grease impregnated with copper specifically used for its waterproof and stability (longevity) properties. This lubricant does not wash out or break down even under years of exposure.

I do not build knives for collectors or casual users. I build them for the hardest users and the most extreme environments on this planet.

The reason that there are people who take their Emersons apart to clean or re-lube is simply, because they can. Emerson Knives was the first Knife company to make knives that could be completely disassembled by the user. This was impossible for any other production knives at the time and voided the warranty for most production knives. Once again, knowing both the purpose and the environments our product would be serving, I built the knives to be just like a gun. You can take it apart, clean it, tune it and replace parts as needed. No other so called "hard core" knife company even understood that simple need.

On my own knives, I have never ever changed the lubricant on any of them and some I have carried daily for over 5 years. They are knives that I simply picked up off the assembly table and put into my pocket.

I build my knives to a different standard. A standard unknown or perhaps ignored by other knife companies and a standard probably not understood by those who are casual users of Emerson Knives. That standard is so that any and every Emerson Knife can be carried into the harshest and most extreme environments on this planet and perform anytime, anyplace, without concern.

So in the end to answer your question, what purpose does it serve? I hope I have given you an answer.

Thank you for your support of Emerson Knives.

My Best Regards,

Ernest Emerson
 
I like that despite the wonderful ergonomics and design, the construction is kept simple and tough.
 
I know I keep learning these things personally as I carry an Emerson daily. These things, that Ernest has pointed out, aren't obvious to even most knife knuts, you come to realize it as you use them. It seems many don't use their Knives, or any singular knife, enough to appreciate it though.

The salt water thing is interesting, it makes sense to me now.

I know many do replace washers, but I haven't I find that use wears them in to be very smooth, much like a gun, as Ernest said.

Thanks for sharing this, and thanks to Mr. Emerson for a great product.
 
I wish we knew what the "graphite grease impregnated with copper" lubricant they use is. To my knowledge, they've never specified what exactly it is that they use. Please correct me if I'm wrong.
 
But 154CM isn't 100% stainless steel. And some knives are just satin/stone wash combination without coating.

it appears to be an anti-seize compound, Permatex 80078 or similar.

That product is described by Permatex as: "A highly refined blend of aluminum, copper and graphite lubricants. Use during assembly to prevent galling, corrosion and seizing due to weathering or chemicals. Anti-Seize assures easier disassembly. Temperature range: -60°F to 1600°F (-51°C to 871°C). Salt, corrosion and moisture resistant – ideal for marine use. Non-aerosol version meets Mil Spec #907E. Aerosol - Level 3 *NFPA Fire Code 30B - See more at: http://www.permatex.com/products-2/product-categories/lubricants/specialty-lubricants-anti-seize/permatex-anti-seize-lubricant-detail#sthash.dO2q8I0K.dpuf"

It certainly sounds like it would be suitable, at least just based on the text description. I have no idea how to interpret any of the more technical info. Also, it includes aluminum in addition to the copper and graphite that Emerson mentioned; I don't know if the aluminum wasn't relevant enough to be mentioned by Emerson, or if he's using a different product.

What it boils down to is what I said in the first place: I wish they would just state what they use, so those of us who think the OE-spec is good enough can just use the same stuff without having to guess.
 
I'd like to re-address the subject of the grease used by Emerson.

Based on the earlier suggestion that it might be Permatex 80071, I researched that product on Permatex's website, as I mentioned earlier. http://www.permatex.com/products-2/...ti-seize/permatex-anti-seize-lubricant-detail It says that 81343 is a smaller package of the stuff, and a local auto parts store had 81343 in stock, so I got a tube. Even a one-ounce tube is quite a lot, so I'm glad I don't have four ounces sitting around now.

Here's my concern. First of all, the 81343 package and tube make no mention I can find of having any copper. So even though the Permatex website says it's the same as 80071, I have my doubts. Also, the stuff is silver in color. Somewhere else here, I've read that the stuff that comes in Emerson knives is black.

Permatex says these products are aluminum with copper added. This is apparent from the silver color of this stuff. But in the OP above, from Mr. Emerson himself, he says he uses a graphite lubricant with copper added. That's probably why the stuff seen in from-the-factory Emerson knives is black.

So, still much confusion on my part, along with doubts that 81343 or 80071 is the right stuff. And overall, I still wish EKI would just say what they use, so we can get the same stuff. Or, if it's proprietary, sell it on their website so we can get some for doing our own maintenance.
 
I also would like to get the OEM Emerson grease, I have no doubt it does the job.

Until then I do want to share my experience with John Deere Multi-Purpose SD Polyurea Gun Grease - TY6341. I had some on hand (used in my manual trans shifter) and after a thorough cleaning of a 2014 Combat Karambit and 2015 CQC7 used a THIN film on both sides of the Nylatron washers and a more generous amount on the blade pivot. IMHO the action is much improved and the specs on the grease would seem to indicate it'll be an effective lube, plus it's cheap and widely available.
