The Mjolnir (Thor’s hammer) one of the most iconic and powerful symbols was certainly a weapon but It also occupied a central role in rituals of consecration and hallowing. The hammer was used in formal ceremonies to bless marriages, births, and funerals as well.
The Valknut symbol is an ancient symbol associated with the god Odin of Norse mythology. The Valknot, or "knot of the slain," often represented the afterlife in old Norse carvings and designs. It is often considered a symbol of Odin, the ruler of all of the Norse gods but also the Norsemen’s god of war and of death.
