Need some help with German Naval Dirks etc.

Hello forum
Long time reader, first time poster.
For quite some time I have had this dagger lying around, it was passed down to me by my grandfather who obtained it overseas and based on all my research so far it is a naval officers dagger, 2nd model. (see link for very similar related pictures) Wittmann Militaria - 2nd Model Navy by Eickhorn

My main questions are referring to what rank these specific types of daggers were assigned to, and I suppose following that how rare that would make these particular blades?
Thanks for the help in advance forum!

 

Germania International Kriegsmarine scroll down to dagger, which is same as the one your referring to..

one or two of the guy's here will know the issuing of daggers..

 

post a photo(s) please then we can go from there, am assuming you have the short Dolch worn by Offiziers and not the sabre to higher ranks ?

 

The photo in my first post is as close as I can find to an exact match on the internet.

 

You said that you have the dagger lying around...pick up a camera and take a picture.

 

I am curious as to what 'higher ranks' you are talking about. It is my understanding that dress regulations for Officers and senior NCO’s prescribed wear of side arms as a component of particular forms of dress. Officers and certain senior NCO ranks were responsible for purchasing their own uniforms, including side arms, and as a result were allotted a clothing allowance through the Navy’s Offizierkleiderkasse system. The sword was just a more expensive option and one that was not purchased by as many Officer's and senior NCO's. To my recollection I have never seen a photo of Doenitz wearing a sabre.
