Daggers Identification please

[Dolf]

Gentlemen,

Can the experts on this matter please help identifying these two daggers?
I believe they are Soviet, at least one of them has a date, 1978, so apparently from before the end of former USSR.

All information, such as if from the Navy (at least one of them seems a Navy Dagger), Army, the rank, the value, etc, is very much welcome.

Thanks a lot,

Here is the 1st Dagger:

Here is the 2nd Dagger:

The daggers are 1970's officers parade daggers with belts; navy and army. Nice daggers, worth about $150 each with belt.

Doug,

Thank you very much.

$150 is a buying or a selling price? :)
Bothy look in excellent condition but on the Navy one there is a small rivet missing, visible on pic3 of the 1st Dagger.
Btw, what is that "strange" symbol on the one from the Army?

Thanks again,

Dolf

It is the mark of the ZIK factory.
