That definitely looks like where the curved and flat bevels came together during machining. Probably two different machine passes that didn't align correctly. It looks most like the round cutting tool stopped early where they come together, leaving a raised ridge, like grass sticking up where you didn't overlap the mowing enough.
Under warranty?

Not 100% certain of the meeting of the grinds or the belt stuff,
But on a zt I have I have a distinct line like that on one side only.
Under a loupe it looks like the counts per mm became changed.
Almost looks lke the member who said a pass did not take.

If it's in the same place, both sides, obviously something that clamped both sides at the same time. Sort of like it hit a V-sharpener or something...not that it did.
If it's steel-inherent, it must be some kind of flaw vein. Where are the steel guys?

First & foremost, Mpdog: it's quite refreshing, to see bathroom pictures posted here, without feet in them. :thumbup:
As for the ridges on your Microtech DOC. I wouldn't quite call those imperfections: "normal."
I've owned a few Benchmade 4X Balisongs, that had these same type of uneven grinds.
If this MT DOC were mine, I wouldn't be returning it for this reason alone...& please don't forget to take into consideration, Microtech's warranty/repair departments poor history of very lengthy turn around times.
If you look at where the lines terminate on the edge and flats of the blade, you can see that they are V shaped - especially between the C and the D. This is a raised ridge from the grinds not quite meeting. I would think you could feel it with a fingernail.
I'd keep it if it was a Buck. But if this is a knife that is priced high because of its precise machining, this would fall well short for me of that aim. Whether that means return or warranty is up to you, but I think this example would have less resale value as well as the flaw being something you'd never be able to look past.

Weaker? I doubt it.
Being that it's machine ground and not hand ground, I assume it's a line from some machine process that transitions between the different bevels. A hand ground blade would not produce such a crisp line like that on each side, which leads me to believe it's just part of their automated grinding process.
