Mjölnir, the Thor's Hammer made in Catia and rendered in Keyshot 9 Pro.

n Norse mythology, Mjölnir (in Old Norse Mjǫllnir, in Icelandic Mjölnir, in Danish and Norwegian Mjølner, in Swedish Mjölner) is the hammer of the god Thor.

According to later Icelandic sources, Mjölnir is described as one of the most feared weapons in Norse mythology. In them it is related that it is used to defeat all who challenge the supremacy of the Æsir. Although it is generally depicted and described as a hammer, it is sometimes referred to as a mandarin, an ax or a club.1 One of the most popular myths about its origin is related in the Skáldskaparmál, where it is mentioned that the Sindri and It was forged by Brok and gifted to Thor as part of a bet Loki placed on them.

Mjölnir means 'shatter', and refers to the hammer's pulverization ability. It is related to the Icelandic verb mölva ('to crush') and mala ('to grind'). Similar words, all coming from the Proto-Indo-European root melə, can be found in most European languages: the Slavic words melvo ('demolish') and molotu (hammer), the Dutch meel (to grind), the Russian Молот (molot, ' hammer '), the Greek μύλος (mylos,' mill '), the Latin words malleus (' hammer ') and mola (' mill ') and the English words meal (to grind), mill (' mill ') and mallet (' mallet '). It has also been suggested that the name, apart from reflecting the fabulous powers of Mjölnir, could also allude to Thor's agricultural nature, since in his early days he was a divinity worshiped by farmers.

An alternative theory suggests that Mjölnir could be related to the Russian word молния (molniya) and the Welsh mellt (both translated as 'lightning bolt'). This second theory is related to the idea that Thor was the god of thunder, which is why he could have used lightning as his weapon.
