There is a lot of 2h swords in floris but all of them are awful, but dont get me wrong they are historicaly correct with the clamshells and rings but thats what also makes the awfull.

I suggest you make some simple 2h swords like the flamberge (keep the parry hooks and the leather), but with a straight blade and choices of the colour of the leather, like making two, one black leather one brown leather and NO RINGS OR CLAMSHELLS.
Such zweihander is in the perisno mod but it hasnt got leather on the blade and the texture is awful.
