Firstly its your knife and you have to be happy with it. If it's "like-new" and you don't like it TNK should return it in good faith, which I am sure they will.
Having said that, it's important to understand these are not true "Damascus Steel" blades, though that term is used universally to decribe them these days. They are 'pattern-welded' blades. The pattern is not created by the acid etching, the etching simply reveals the pattern that is there. These patterns exists in three dimensions, and are not uniform though the stock of the blade, like you might think. The swirls of the "Spirograph" effect get larger and smaller, and the side of the knife simply reveals one plane of that pattern, which may contain "smudges", which are in fact the places where the pattern is transitioning from one steel to another. When the blades are ground it is impossible to predict where these smudges will be, so a portion of the cost of Damascus blades is to cover discarding blades that turn out very smudged, that customers would reject. All of the CRK patterns have these smudges on them, in varying degrees, with some very sought-after perfect patterns popping up from time to time. The ladder Damascus seems to the least prone, and the smudges are almost unnoticeable in the raindrop due to its already mostly random nature.
That is the crazy crux of the Damascus blade issue. The repetitive pattern appeals to our OCD, but the pattern itself is often flawed, which annoys us! CRK could issue only perfect DT Damascus blades, but they would have to discard a hell of a lot more blades than they do.
Good luck with whatever you choose!!
