It's my pleasure! I hope that some of it has been helpful. ^_^
Ah, I'm glad to read that you have weapons other than swords already in the works! (Already being forged, one might say. ;P)
As to more-unusual swords (well, dagger-like things), the one that springs to mind is something like this: https://en.wikipedia.org/wiki/Mambele
But more generally, multi-bladed weapons and the like: think of Darth Maul's two-ended sword from the Star Wars prequel trilogy, or The Kurgan's pronged sword from Highlander (see here: https://www.imdb.com/title/tt0091203/mediaviewer/rm954182401/ )
Otherwise, it sounds like you have things in hand. ^_^
