Not long ago I've enherited this Japanese sword.
The story is that my great grandfather who was a captain sailing the seven seas brought this home to Denmark after a visit to Japan before WWI.
He had a rather large weapon collection, that he at some point was forced to sell and this sword is the only item he kept. Later it was hanging on the wall in my grandparents appartment and now its mine.
Opinions are very welcome. See photos below.
@Mod, for some reason I cant add the photos to the text box.
