I got a brand new Super CQC 7 just recently. The quality seems really good except theres some copper coloring on the part of the blade thats facing the liners by the pivot. And one really small spot of the same copper color by the back of the serrated teeth.
 
EmersonRep will be here to asssist but just use that baby and that color will go away.

Ive used the kershaw emersons for awhile now and I gotta say a real emerson is scary sharp compared haha
 
It's hard to say without pics, but to venture a guess I'd say it's the factory lube Emerson puts on the knives. It's a copper impregnated grease.
 
I will try to wipe it later but i didn't take pics cause i dont think the tint of the color will show in a pic.
 
Sounds like Emerson pivot grease remnants which is a mix of moly grease and anti-seize compound (black grease with copper). Clean it of using a light solvent to help make those particles off the coating to avoid marks from aggressive wiping assumin it is a black coated blade which you didn't mention Damatinc. Is it? Satin/stonewash blade would be a different scenario.
 
Yeah its a satin/stone. The the thumb ramp with the jimping is also a darker color then the rest.

Looks like remnants from the heat treat process that wasn't fully removed from the final finishing of the blade. Some of my SF Emersons are like that. Not a structural concern, cosmetics. See if pencil eraser will do anything.
 
Thats what I thought. I was just worried about it being over ground and the heat treat being messed up.
 
The serrations are ground in using a wheel. If it were from heat, it would be more consistent. I grind down steel strips from time to time at work and those have been consistent in the zone being heated up from such.

That has happened, not out of the question. I have one satin finish that has a weird colored tip. It was heated a bit too much during the grinding it looks like. As far as consistency goes, you can see it faintly from right to left all the way through the serrations.
