Thor has been a mainstay in the Marvel Cinematic Universe ever since phase one. Unfortunately, the same can’t be said about the God of Thunder’s mighty hammer. That was destroyed in Thor Ragnarok, however it did make a triumphant return alongside it’s new owner, Jane Foster, in Thor Love and Thunder.
What is Thor’s hammer’s name?
Thor’s hammer is called Mjolnir and it was given to him by his father Odin. Odin gave the enchanted hammer to Thor as a way to channel his powers just before his planned coronation to become king of Asgard.
There were two people to wield Mjolnir before Thor. It’s original owner was Odin himself who then passed the war hammer to his daughter Hela to fight alongside him. Mjolnir was eventually taken from Hela when Odin imprisoned her in Hel after she turned evil.
What is Thor’s Hammer made of?
Thor’s hammer is made of Uru metal which is one of the strongest substances in the Universe. Uru is a metal ore found only on the first moon that came into existence. It is incredibly durable. It’s main property is that it has the ability to easily absorb and hold magic. Uru is highly difficult to forge and can only be melted under extreme circumstances, such as in the heart of a dying star.
Where was Mjolnir made?
Mjolnir was made by the Dwarves on Nidavellir at the request of the Agardian Royal family. Odin himself requested this to be forged to allow him to wield one of the most powerful weapons in existence.
Who can lift Mjolnir?
Before Odin stripped Thor of his powers and sent him to Earth with his hammer, he enchanted the weapon so that only those who are worthy could lift it.
Whosoever holds this hammer, if he be worthy, shall possess the power of Thor.
Odin’s Mjolnir enchantment
Since then, in the Marvel Cinematic Universe, we’ve seen a handful of characters lift the mighty hammer. These people are:
- Odin
- Hela
- Thor
- Vision
- Captain America/Steve Rogers
- Jane Foster
With Mjolnir now put back in one piece, it remains to be seen if any other Marvel characters will lift it in the future.
When did Mjolnir break?

Mjolnir broke at the hands of Thor’s sister Hela during the events of Thor Ragnarok which was released in 2017.
Can Mjolnir summon the Bifrost?
The simple answer is no, Mjolnir cannot summon the Bifrost by itself. Thor always needed Heimdall to activate the Bifrost to get him out of sticky situations, or just for general inter-realm travel.
However, the weapon that is forged for Thor in Avengers Infinity War, Stormbreaker, can summon the Bifrost. We see Thor use this to his advantage on a few occasions. Such as traveling to Wakanda to face off against Thanos’ army in the closing scenes of Avengers Infinity War.
Mjolnir vs Stormbreaker: which is more powerful?
While Mjolnir is incredibly powerful, it was not originally intended to be used by Thor. It was forged for Odin to be used by Odin. Meaning it’s not perfectly suited to Thor like Stormbreaker is.
Stormbreaker is forged specifically for Thor to be the most powerful weapon on Adgard, according to Eitri, the dwarf who forges the weapon on Nidavellir.
It’s a mold. A king’s weapon. Meant to be the greatest in Asgard.
Eitri on Stormbreaker’s power
Stormbreaker is also able to summon the Bifrost, something that Mjolnir cannot do. Although Mjolnir’s enchantment only allows it to be used by those who are worthy Stormbreaker can be used by anyone.
Are Mjolnir and Stormbreaker sentient?
Looking only at the evidence from the MCU it would appear that Mjolnir and Stormbreaker have some level of sentience. In Thor Love and Thunder we see Stormbreaker get jealous of Thor’s affection for Mjolnir. While it was likely done as a gag by Director Taika Waititi, this sentience might actually come from Stormbreaker’s handle which is made from Groot’s arm.
When it comes to Mjolnir the answer isn’t quite as simple. While Mjolnir displays sentient characteristics such as only allowing those who are worthy to lift it, this comes from a magical enchantment.
While it can’t be confirmed for sure, the evidence suggests that Stormbreaker is sentient and Mjolnir is not.
