Hello grzegortz:

What you have there is a dagger, not a knife.
Knives are usually single edged, and made for cutting.
Daggers are double edged, usually (but not always) only sharp at the point, and made exclusively for stabbing.

And just in case you wanted to know, I could be wrong, but I seriously doubt if that piece is of Third Reich vintage.
I hope that this is helpful to you.
