ED.

~(~KK > ~K) is equivalent to: It is not the case that not knowing is a necessary condition of not knowing that you know.

Yes, but you are still assuming that this premise is true are you not?
Does it not boil down to the acceptance of your premise since your form is valid?

@fast,

Contradiction (Stanford Encyclopedia of Philosophy)

@fast,

Two terms are contradictories (or negations) if one or the other must apply to a thing, but both cannot apply to the same thing. On the other hand, two terms are contraries if only one can apply to a thing, but neither applies to some things.

contradictory vs. contrary

Not exactly a great source. I'll try to find a better one.

Why would you need to, is there any doubt what the terms mean? Though the above explanation is not good since it is about properties of a thing and not about propositions which this thread is about.

So the answer is that it is true because it is true?

I see a valid form but what makes it sound?

But you have not given me a non-question begging reason. That is what I am looking for. I know of two arguments against the KK-principle, namely the argument from counter-example and the argument from infinite regress.
