I am not familiar with the history of Hungarian blade making, but I have no doubt that this blade was made in Solingen. It says Eisenhauer on it in large letters.

I don't think this was a dancing sword, unless it was a dance of death.

It's a miracle the knuckle chain survived, most of these shamshirs that I've encountered in books and in museums had the chains missing, being delicate as they are. The beads have ornamental quality, pretty as they are, and maybe other significance, perhaps as the Islamic rosary beads?...
