That is a sword...
It has no pommel to end one's opponent rightly, so it's not a sword!
Actually, it's very interesting stuff, what constitutes a sword and knife/messer. Gonna take this off tangent a bit - some historian could correct me, but I understand that in medieval Europe, a sword is a sword because it's not built like a knife or messer - a knife has scales. Something to do about swordsmiths only being allowed to make swords and knifemakers only being allowed to make knives - guild policies and all that. So, my understanding is that even if the blade and overall shape is exactly the same, what makes a sword a sword and a messer a messer then was the way the handle was made... again, correct me if I'm wrong.
