Mjolnir

Mjolnir, known more formally as Mjölnir (/ˈmjɔːlnɪər/) is a fictional magical weapon appearing in American comic books published by Marvel Comics. It is depicted as the principal weapon of the superhero Thor. Mjolnir, which first appears in Journey into Mystery #83 (Aug. 1962), was created by writer Stan Lee and designed by artists Jack Kirby and Joe Sinnott.

Mjolnir is typically depicted as a large, square-headed gray sledgehammer, with a short, round handle wrapped in brown leather, culminating in a looped lanyard. The object is based on Mjölnir, the weapon of the mythological Thor.
