That said, notice how the blade on the arm drawn back looks. It tapers down sharply, like AC1 blades and AC2 one built by Leonardo, while the one on the other arm looks to taper smoothly, like Giovanni's and Ezio's roman blades. This makes me think it's either to show they're an upgrade, later than a matching set.
