Hammer-shaped pendants were carried as protection from the thunder god. A=Finnish Ukonvasara B=Scandinavian Thor's hammer C=Icelandic Thor's hammer
This kind of stone hammer could be the original meaning of Ukonvasara

Ukonvasara, or Ukonkirves, is the symbol and magical weapon of the Finnish thunder god Ukko, similar to Thor's Mjölnir. Ukonvasara means hammer of Ukko; similarly, Ukonkirves means axe of Ukko. It was said that Ukko created lightning with Ukonvasara.

Ukko's hammer was probably originally a boat-shaped stone axe. When stone tools were abandoned with the advent of metalworking, the origins of stone weapons became a mystery. Stone axes, so-called thunderstones (ukonvaaja in Finnish), were found in the ground, especially after drenching rains washed away dirt. They were believed to be weapons of Ukko, stone heads of the striking lightning. Shamans collected and held stone-axes because they were believed to hold the power to both heal and damage.

Modern Pagan Finns sometimes carry hammer or axe pendants around their necks, much like Christians sometimes wear crosses.


According to Asko Parpola, the Sanskrit vajra- and Avestan vazra- both refer to a weapon of the Godhead, and are possibly from the Proto-Indo-European root *weg'- which means "to be(come) powerful". It is related to Proto-Finno-Uralic *vaśara, "hammer, axe", but both the Sanskrit and Finno-Ugric derivatives are likely Proto-Aryan or Proto-Indo-Aryan but not Proto-Iranian, state Parpola and Carpelan, because of its palatalized sibilant.[1][2][3]

Unto Salo [fi] believes that Ilmari, another Finnic sky god, is the origin of Ukko, but that as Ukko Ilmari experienced very significant, although far from total, influence from the Indo-European sky god especially in the form of Thor.[4][5] Others believe that Ukko's original name was Baltic Perkūnas.[6]

Perkūnas is pictured as middle-aged, armed with an axe and arrows, riding a two-wheeled chariot harnessed with goats, like Thor[7] The name Thor descends from the Proto-Germanic theonym *Þun(a)raz ('Thunder'),[8] According to scholar Peter Jackson, those theonyms may have originally emerged as the result of the fossilization of an original epithet (or epiclesis) of the Proto-Indo-European thunder-god *Perkwunos.[9] from which Perkunas also descended from [10]

Indra is described as using the vajra to kill sinners and ignorant persons.[11] Indra's mythology parallels Perun, Perkūnas, Taranis, and Thor, suggesting a common origin in Proto-Indo-European mythology.[12][13][14]
