Kershaw spec bump coating faded

[DavidW3]

Tonight I cleaned my spec bump (the one with 154CPM and was dated Oct05) with warm water and dish detergent. Big mistake! After I was done, I noticed that some of the color of the coating had faded. Now the blade has noticeble patches of grey to darker grey on it. Perhaps I should have known better because earlier today, I wiped the blade with some WD40 using Q-tip. At that time I already noticed some reddish brown color somehow got on to the cotton of the Q-tip stick. Still, didn't know that the coating could come off so easily. So don't repeat my mistake, folks.

Oh, is coating covered by the warranty? I mean, a knife with that price tag...

Also, I noticed that my spec bump is actually not pointed. By that I mean the very end of point is not like /\ . It is more like |\

Is your spec bump like that?

Sorry if I haven't made it clear to you. I just wish I had a camera.

Surely you know someone with a camera?

I'm planning on buying one of these knives tomorrow, so I guess I'll see for myself.

Is the black coating on the blade the same as on the Kershaw Blackout? I've had my Blackout for years and nothing has messed with that coating...

Take some cooking oil or mineral oil and wipe on the blade, then wipe off excess. I have used the lube I use on the pivot, but if you use the blade for food prep, use the cooking oil.

When the blade was sharpened it was probably held at two different angles. I take care of this by just resharpening the knife. I use a Lanskey.

Hope this helps.

Nothing wrong here. This is the nature of this coating - same I have with MOD Mark II and other knives. After soap it turn faded, but any oil, fat etc fix this problem instantly - ask Chuck Bybee

He has perfect silicon cleaning close - Item No: SCC01 - $2.50 as I remember. It will fix this "problem".

This is great knife and great coating. I think only BC coating may be better or TiAlNi...

Thanks, Vassili.

P.S. That patches are may be due to WD-40 (which is mostly kerosin)- it may protect some parts of the blade from soap more then other parts.

I figured it is just detergent that filled the gaps of the bead-blast. I think that is the finish of the blade under the coating. You just need to oil it to remove the detergent and it will become black again. Don't know what the brown color is. I am hoping that it is not rust. Coated blades don't usually rust that easily, even if it is 154CPM.

Experienced the same thing. I actually think, what you are seeing is the really color of the coating. Just wipe it down with a bit of oil and it looks again slightly shiny and black. Its DLC, you are not going to rub that stuff off with anything other than a real abrasive, even a missed swipe with the Sharpmaker rods didn't do any damage to mine. Slipped on a 1000 grit waterstone though, and that did it.

Thank you guys for all the quick replies!

As suggested, I ran into the kitchen and wiped the blade with some cooking oil. Viola, the coating is back!

I know there's a reason I visit this forum regularly

Thanks again for helping out!
