Dutch navy poniard?

[cel7]

I bought this poniard last week. It is clear to me that it is a navy poniard and probably Dutch. The use of a poniard with the same type of grip was also fashionable for a while in the British, French and Russian navies. The strange thing, however, is that it has a shield with a lion leaning on an anchor. Now I thought I would manage to find this emblem somewhere but it just gave me a headache. I continued my search across the border and the only thing that looks like it (so far) is the coat of arms of Düsseldorf in Germany. However, that lion has a double tail and no sword in its claw (In addition, it would be strange that a coat of arms from Düsseldorf would be on a poniard like this).
The poniard is almost 50 cm long and has a triangular blade. Marked with B.S.B, which stands for Benjamin Schimmelbusch Solingen.
Does anyone recognize the emblem on the shield?
