This sparkling name from Norse Mythology is borne by the blacksmith dwarf, who, along with his brother Brokkr, forged Thor's hammer Mjǫllnir and Odin's golden ring, Draupnir. Also known as Eitri in mythology, his name means "sparkling" or "someone who sprays sparks", likely in reference to his work with metal.

A variation of the Old Norse name Sindri, which is borne by a blacksmith dwarf in Norse mythology, who, with his brother, made Thor's hammer. With its appealing meaning "sparkling", this form is familiar in Norway and was particularly popular in the 90s, when it ranked #21 in the Norwegian charts.
