I remember when Fab made that funny looking sword. I admit it kind of put me off. You are totally right it does resemble many fantasy swords. Kudos to him for making something that doesn’t fit the expectations of the period.
That part of the ‘strong’ of your blade is often where you ideally want to parry, trap the opponents sword against your cross. If you have a blade there it’s just going to get dinged. One of my longswords has a big notch right at about that point. It could also be a half-swording grip like you see on some of the really big ‘true’ two handed swords.
