It looks like someone stole one of those gasoline pump handles and stuck it where an actual grip on a sword is supposed to be. How do you even use this thing?
what kind of loving sword design is that
That is the dumbest sword design I've ever seen, even worse than the gunblade
The swords, in my guess, aren't meant for fighting other people, and have handles designed like that to remain in one's hand after a high-velocity strike against a titan. They don't really swing them that often, they usually just let the momentum carry them and the blade to their target.
