Was in a leather pocket slip. Removed my knife and saw this build up on the coping blade. Looks like a battery terminal. Have any of you experienced this?

Have not hard used this knife. Have only opened boxes and such.
 
For what it's worth, with my CV blades I always wipe off the blades at the end of the day when I've carried the knife that day. Even if I'm taking the knife out of the pocket and putting it on dresser, I wipe the blades. I use an old tee shirt with mineral oil, and occasionally put a little more oil on the shirt.
 
If it did not pick up something to do that to it on what you cut with it,more than likely it picked up something on the leather slip. Either way something did that ,something ph + or -
 
I´ve been told, that I should NEVER leave a carbon steel blade in a leather sheath or so because of the acids that are used in leather production. They will definetely cause corrosion on carbon steel blades. Concerning this you´re happy that just one blade was infected
 
You put it away wet. During the day you probably got wet or sweaty and that moisture worked it’s way in there. Overnight the moisture won’t evaporate if the knife is closed, especially if it is in a sheath.
 
Wow!!!! I've had blades rust and pit overnight before, but nothing like that. Something corrosive had to have gotten on the blade. I'm not buying into the leather slip theory, with that level of corrosion. Did you use the coping blade to cut anything yesterday?
 
After taking another look at the pictures, I can’t really tell how deep it is from the pictures. Is it surface level patina or is it different? After you get it cleaned up please show a few more pics. I hope it isn’t much more than a surface level patina.
 
That looks like something smeared on the blade. If it were from the leather I think you would notice dramatic corrosion on the part of the blade that is exposed out of the blade well, and it would be on both blades. That looks like the blade is covered in something.
 
Unless there a Tube Queen I normally store mine in a leather slip/sheath. But could definatley see how leather could be bad because at times they feel damp. But I’m always wiping my blades down and either putting some Flitz and or oil on them so never had a issue .
 
I've left mine in a leather pocket slip overnight once or twice.
I've not had that happen to me.
Strange. I'd freak out if that happened to me.
 
No pocket slip did that to that knife. You cut something corrosive/nasty with that sheep foot blade and did not wipe it off. Then you left it in the pocket for a time. Just lack of cleaning the knife after use and neglect. Nothing more.
 
That's some interesting chemistry going on there.

It almost appears that something liquid has got in between the pull side of the blade and liner and sat there for a while. And may be at the bottom of that blade well as well from the other picture.

I would think the exposed part of the blade (when closed) would have more corrosion if the leather sheath was to blame as thats where contact would be made and people have been storing 1095 blades in leather sheath for quite a long while without that happening overnight.

Of course, those are, admittedly, just random keyboard warrior guesses.

But I'd be curious to see if anything had been done with/to the knife recently that could also be a factor.
 
When I cut open boxes, I only cut the tape- never the cardboard. Cardboard dulls a knife very quickly. If it has to be broken down more, I’ll tear it by hand or
use a box cutter.
That said, that does not look like rust or corrosion. It looks like the glue gunk from packaging tape. With luck, that’s all it is.
Clean it asap.
Then get in the habit of wiping the blade on your shirt tail or something every time you close it. At the end of the day, wipe it again, maybe a tiny bit of Nortons on the blade and joints and blow the lint/ dirt out.
 
Wow that is wicked build up... Like said above, that was not caused by the slip but by somthing you cut. Polish it off and repost some pictures!
 
For what it's worth it's carbon steel, if you use it will eventually stain.
 
that is gnarly! learned my lesson with knives in leather sheathes. even fixed blades dont stay in their sheathes mostly. well i do examine now and then.
