My knife arrived in pristine condition... but i quickly put an end to that. I bought this knife to be a user, so a friend and i took a little hike and i tried some batoning with the DMDC. When i got home I knew a needed to clean it up... all a had at the time was some break free clp but it removed all of the grime from by blade. After scrubbing the blade down for a while i was left with a very clean, slightly scuffed up, well oiled blade. A few days later i picked it up and noticed some dark gray lines forming near the edge of the blade. I'm really not concerned as long as it's not going to affect my blade in any way other than cosmetically. But i did think it was a little odd that we are the only ones reporting this issue.

I don't know if there's anything to this, but my knife was also inspected by #18
