Eckesachs

Eckesachs (エッケザックス Ekkezakkusu, translated Exaccus in fan translation) was used by the Hero Hartmut, along with the Sword of Seals to combat dragons during the Scouring. After the Scouring, it became the royal sword of Bern, usable only by its king. In Fire Emblem: Fūin no Tsurugi, Zephiel uses it in his battle with Roy and also uses it in a fight with Cecilia.

The weapon itself is very unique in design. Having no known sheath, the blade is simply carried around in a scepter form instead of being in a case. When it is actually used, the sword mechanically morphs into a huge blade of overwhelming power. Zephiel transforms it into a sword by spinning and thrusting it. The sword apparently has some affinity with the element of electricity, because it draws thunder when Zephiel attacks with a critical hit and sends a shock wave when he attacks from a distance.

Eckesachs can only be used by Zephiel, and can only be used by the player in Trial Maps

There is no known title bestowed on Eckesachs therefore it can be assumed that Hartmut might be the one who bestowed titles for the other 7 divine weapons

Origin
Eckesachs, or Corner Sacks, is a sword used by the German hero Hiebschwert. A sage named Dietrich von Bern described this sword, leading to the conclusion that both Bern and Eckesachs are of German origin.
