This is a German Army officer dagger used during the Third Reich period. The dagger is a standard model for army officers, featuring a swastika and eagle insignia on the crossguard. The blade bears the maker's mark of Eickhorn, a renowned German edged weapons manufacturer.

Condition is near-perfect.  Blade is 99% with only a very faint stain near the tip, probably removable.  Exterior fittings are heavily silvered, with hardly any wear (only a couple of light marks on the pommel).  Screws unturned.  Grip perfect.  Portepee in outstanding condition.
