most likely what you're seeing here is scuffing and aesthetic flaws in their etching effect, not necessarily flaws in the hamon or blade. nearly all Hanwei katana with differential heat treating feature a very heavy, "frosty" looking effect on the hamon to simulate a more complex process of using finger stones to bring out the hamon. this is achieved by using a chemical etch treatment to create contrast, which is cosmetic and should have no real negative affect on the functionality. I'm not sure I've seen a Hanwei katana blade without at least a couple of scuff marks in the etching, which can happen from rubbing on the koiguchi or during manufacturing, packing or shipping. it shouldn't be an issue but if it really bothers you, you can re-etch your blade with vinegar or lemon juice. there are many videos showing how to do this. or, you could remove the current etch and leave it without an etch at all. the hamon might be less visible afterward but many feel it's more natural looking that way.

Well, thanks for the insights and numerous responses. I did find a scratch or two on the mune, but I don't really mind those, as they are rather minor. A skilled eye might have spotted them instantly, it took me quite a bit to notice them. So far, I guess I'm happy with what I have. Will have to read a bit more on maintenance though, as I'm unsure if the tsuka needs to be removed for maintenance (there's steel in there after all) or if the oil coating of the blade alone is sufficient (= status quo, never took the tsuka off).
Now that I got what I wanted, I already know what I want next, if budget weren't an issue... That Celestial Katana does look pretty.... Expect more "fun" questions once the budget allows it

Sword collecting is like peanuts, you can’t stop just with one.
