Here is a tip for anyone buying a sword:
The real “historical accuracy” of a sword is judged by the weight. I’m talking real swords used in battle, not ceremonial swords.
Most modern replica swords are 2-3x the weight of original medieval battle swords because it’s simply cheaper to produce.
I have a replica Ancient Greek xiphos that weighs 2.5kg (5lbs) and a historically accurate one that weighs 650gr (1.2 lbs). The heavy one is immediately obvious that it is not real, as it is unusable in combat because it’s impossible to swing fast. The accurate one simply feels like a giant knife, very light.
If you want a sword that is accurate and that you can swing and practice with get one with a historically accurate weight. In my opinion accurate weight is really the #1 criteria. (Apart from structural rigidity and build quality obviously).
