Did you try to clean the blade with water and a sponge?

If you're lucky, the Tuf cloth left something on the blade that causes that discoloration. I've personally never seen that on one of my BB knives when they were new.

It seems strange though that the discoloration seems to extend into the pivot aera where you probably didn't reach into with the cloth in the first place, so maybe it is something else than just the result of tuf glide.

Well, if anything else fails, you've just found which one to EDC and which one will be the safe queen :) The EDC'd blade will be looking "used" soon enough anyway.

Thanks for your help Dennis...

I will try to clean it with water we'll see how it's turn out.

I think I fixed it...I think when I used Tuf Cloth to wipe it down (just to do it like I done to all of my knives before I'll keep them in the box for storage :p )
I probably done something wrong....dried out the blade.I thought I have this Honing oil just to tried it out by soaking the blade with the oil then leave it after that I wiped it dry.I doing this about two times.It looks ok to me now. :)
I hope that sal reading this and teach me some lesson...

Lucky me ha ha :D

Reminds me of the time my mother went to the doctor cause her hands were blue.

It turned out she was wearing some new bluejeans. Apparently they were less than colorfast.

I'm probably going to sound like an idiot here, but why would you whipe down a NIB knife? Does it really need to be cleaned right away?

Well, there was some oil on the blade when I got it then I carried in my pocket play with it for awhile. Actually I just tried to clean up some of the fingerprints and those lints from my pant really. I had Emerson knives with black blade and I never have these kind of ploblems with Tuf Cloth or they have a different type of coating on the blade :confused:

The exact same thing happened to my USN Endura when I wiped it down with a Tuf-Cloth. I ended up wiping it down with CLP and that seemed to get it back to normal.

What is CLP?

Breakfree CLP is a gun/knife cleaner. The CLP stands for Cleans, Lubricates and Preservative. I used it on my knives until I decided to try the Tuf-Cloth. CLP is not a dry lube/oil and seemed to attract a lot of pocket lint.

Cleaner Lubricant Protector; Its a common way to clean lubricate and protect guns and other items that need lubrication and rust protection. Its an all purpose med light weight oil, usually has Teflon in it. You can buy it at any gun shop or sporting goods store.

Thanks guys

Tuff Cloth works by leaving "stuff" on the blade. If you use the Marine Tuff Cloth on an uncoated blade, you will really notice it. Consider it just the Tuff Cloth doing its' job. :)

The black coatings sometimes holds this stuff pretty well. As you have found out.

WD-40 is great for cleaning blades.

I also use Birchwood-Casey Sheath. A gun product that works great on knives.

What is happening is that a coating of protectant is being left on the blade, this often happens with coated knifes, but it is more noticeable on the Endura for some reason (mine does it too) polymer additives and Teflon rags tend to do this. I used a polymer enriched gun lube and it did the same exact thing.

Exactly same thing happened to my USN Endura. I didn't use any protectant, I just used warm soapy water to clean it, then dried it.

And then I noticed it was turning red.. I was thinking it was somehow rusting.
