Dutch navy poniard?

[corrado26]

In my opinion, the coat of arms on the saber has nothing to do with Düsseldorf, the differences are too important as can be easily seen from the two illustrations. The lion on the sword holder holds a sword in his raised right hand and leans on an anchor with his left, this sword detail lacks the Düsseldorf lion, but instead has a forked tail. The lion, on the other hand, is very similar in basic shape to the lion in the Brabant coat of arms. Over that both crowns are very different, the anchor-lion wears a duke's crown very well fitting to the duchy of Brabant, the Düsseldorf lion's crown is that of a baron!
