Any help in ID maker? Oskar 1938?

Oskar is most likely the original owner of this beautiful dagger and he received it in 1938.

I also think that Oskar was the owner and can´t see any maker´s markings. D.R.G.M. is for "Deutsches Reichsgebrauchsmuster" (patent).

HELLO Garandrew;   beauty dagger!    it appears the hanger fittings have  gold wash left on them.  .......for general officers;    white metal for all other officer grades  GREAT FIND.   BEST;     T BIRD

Is there a General Oskar?

So more than likely a General had this? I know it’s a long shot and o know he was in the Nazi party but I thought of Oskar Schindler?

Thanks for looking and any opinions do welcomed 

How about Oskar the grouch?
