It is very nice that you think that I am much younger than you, but I'll get 76 years old this year and many years of this time I spent in a higher position in one of Germany's military museums. So I know lots of partisans and spontoons and all of them in our house had langets. They have been made for nothing else than battle. The ones without langets are mostly pieces made for representation purposes. As you can see from the two fotos attached, all spontoons except one have langets.
As the blade in question has no monogram or something else what could help to identify it , it was certainly not made for representation and over that and without langets certainly not made for battle. That was the reason why I said that I think it is a piece of historism. But I am not the pope of polearms and maybe I am completely wrong.....................
