Towards the end of Avengers: Endgame, we see

Thanos fighting Captain America. He repeatedly hits Cap's shield with a big double sword thing, which breaks the shield.

How did this happen? As far as I know, we've never seen anything that can damage

vibranium before in the MCU. Black Panther's vibranium suit is not obviously damaged when hit (admittedly just once, remotely) with Thanos’s sword in the battle. Is the sword made from a hitherto unknown metal? Thanos wielding double-sword!

    Your assumption is quite flawed.. Corvus Glaive's blade goes right through Vision's body.. And Vision is made of vibranium. Moreover, didn't Thanos rip off the mind stone from vision's forehead with his bare hands?

    Also vibranium isn't indestructible, just very tough and it hasn't been hit with a giant sword wielded by a Titan on the edge before.

    @PaulD.Waite well, the MCU has established that Vibranium is the strongest metal on Earth. However, there is no proof that it's the strongest in the universe (not counting the comics here).

    Also also, apart from vibranium, vision has only organic tissue over his vibranium shell. so Glaive's blade kinda cut through vibranium once.. So if thanos is giving around vibranium-cutting weapons to his thugs, I'm sure he has something much better kept for himself

I do believe that Vibranium is the strongest element only on earth!

In Infinity war, we see Corvus Glaive cleave straight through Vision as if he were made of butter.

Considering that, it's not so surprising that Thanos would have the element himself.

After all, why would he entrust the strongest weapon only to one of his lackies... errr... I mean, kids, and not himself?

    Worth noting that Vision is not just made of Vibranium, in fact considering the amount of Vibranium Ultron got I would imagine Vision is mostly made of the stuff Helen prints.

    Helen just had a mechanism to print stuff. In the case of Vision, she just printed it. The source material was Vibranium all along. Ultron did manage to get his hands on a sizeable amount of Vibranium, judging by the shipping crate he "bought" from Klau.

    I thought he only got a few vials of vibranium but yeah there might have been more.

    You also have to remember Corvus Glaive's glaive is the sharpest thing in the known universe according to the lore and can cut through anything.

    Civil War showed that vibranium is capable of damaging other vibranium as Black Panther's claws left visible marks on the shield. The Black Panther movie also showed that vibranium originally came from space so it's not unreasonable to assume that other space-faring cultures have had access to the element at some point. Therefore, it's not unreasonable to speculate that Thanos' sword might have been made of vibranium as well.

This was (indirectly) addressed by the film's directors in an interview with Comicbook.com. In short, the strong implication is that his sword is made out of uru, the same material as Stormbreaker and Mjölnir.

“Clearly Thanos is a thousand-year-old character who has fought everyone in the universe and is the greatest: He’s the Genghis Khan of the universe, so he would have the greatest weapon. He knows of Eitri, he’s been to Eitri to have his glove created. Did he have them create his blade as well? Potentially. But it’s interesting that it could destroy the shield.”

Amplified by Thanos' raw strength, this would explain why it can cut through a material as resistant as vibranium with moderate ease.


In the commentary included with Avengers: Endgame.

..he was able to break his Vibranium shield because Eitri made his dual-edge sword from something much stronger. - BGR
