Si euli are a type of knife worn by the people of the north of Nias, a small island to the west of Sumatra. They are relatively rare on the market because most ethnographers and collectors have focused on the more flamboyantly carved styles of the southern part of the island.

They are found in illustrations published by the Italian explorer Elio Modigliani, who visited the island with only four Javanwse hunters/trackers in 1886 and miraculously made it back alive to write his book. He gives them the name si oli.The name si euli which is accepted today appears first in Feldman's study of 1990.2
