The Deus Ex Calibur is an enchanted sword from the 2017 Continuum.
A long scimitar-like sword with a razor-sharp (incredibly sharp, able to cut right through stone with the barest of effort, as seen with Peghook used the sword to decapitate the stone statue of Scrooge), but significantly damaged blade, the Deus Ex Calibur is a cursed sword. As described by Webby Vanderquack, the Deus Ex Calibur won't rest until it slays its target, flying through the air and glowing with power to chase after its victim.
At some point before 2017, the Sword which found its way to the ownership of Scrooge McDuck (who carelessly kept it in his garage in McDuck Manor). In September 2017, Dewey drew the sword on Dewey Duck out of self defense, unaware to the sword's nature and power. As he pointed the sword towards the captain, it flew away from his hands in an attempt to slay Captain Peghook. However, the sword was caught mid-flight and was then used as a weapon for Peghook. Peghook used the weapon in his brief duel with Scrooge and even managed to cleave off the head of a statue modeled in his likeness. However, Peghook was quickly outsmarted by his opponent and banished to the afterlife.
After their trip to Atlantis, Webby was seen playing with the the sword, to the shock of Dewey.
