Take a look here in the Bashford Dean book

I am forgetting the plate off the top of my head but there are similar blade profiles that go from ovoid to hex. France/Alsace/Strasbourg
I have a shard of one of these blades with folded steel, assembled as a dagger when I found it. I'll attach pics I have if interested. The etchings are different but the same "school" and timeline.
Loosely translated; In God is my hope but my sword is my defense

As a good Percy would say; Esperance en dieu!
