Creation & Origin

In a wager with Loki, the dwarves Brokkr and Sindri forge Mjölnir; Loki's interference makes the handle short, but the hammer is otherwise perfect. [S2]S2 · Snorri Sturluson, Prose Eddac. 1220–1235textOpen source ↗

Forged in the underworld forge of the dwarves as a contest-piece against Loki. [S2]S2 · Snorri Sturluson, Prose Eddac. 1220–1235textOpen source ↗

Atlas Power Profile

Interpretive, 0–10. An Atlas editorial reading — not a historical or canonical ranking.

Destruction9

No surviving Norse source says Mjölnir failed to break what it struck; it is the weapon of choice against the strongest foes, including giants and Fenrir's kin.

Defense8

Thor is never wounded in a myth in which Mjölnir is his shield; the hammer is his default protection.

Protection9

Linked to blessing and consecration of marriages, births and houses; the hammer is a charm, not just a weapon.

Magic8

In the Prose Edda its head is engraved with runes; it is tied to Odin's magic and to Thor's thunder.

Durability10

No surviving Norse myth describes Mjölnir being broken or destroyed.

Range7

Thrown and returned; its strike spans the field of battle but it is not a long-range projectile in the way a spear is.

Limitations & Constraints

  • It must be wielded by Thor (or one of equal stature); it will not leave his hand in the myths.

Notable Facts

  • The short handle is blamed on a fly (Loki in disguise) that bit Brokkr as he worked the bellows. [S2]S2 · Snorri Sturluson, Prose Eddac. 1220–1235textOpen source ↗

Where the record is thin

Interpretation note
  • The "World-Scourge" epithet is attested in skaldic verse but its exact sense (world-scorcher / grinder of giants) is debated.
