Mysterious sword

[u/bazzismenace]

This sword from the « tales of earthsea » has been haunting me since I saw the movie, where does this sword design comes from ? I searched and I found its kind of German inspired, tho not sure about that I could be totally wrong. Please help me find out. Thanks !

The style pretty much a La Tene era Celtic one.
