US Inuit Nation Skill Toy: "Yo-Yo" - "Igruuraak"

The Eskimo yo-yo, called "igruuraak" by the Inuit First Nation, originated as an important and widely used hunting tool made simply with sinew and bones. The skills required to use the yo-yo, including dexterity, speed, aim, coordination, strength and stamina, remain important in areas where people subsist off the land.

The object of the Eskimo yo-yo is to make the balls circle in opposite directions at the same time. Each cord is a different length to allow the balls to pass without striking one another.

The yo-yo is a popular tourist art found in gift shops across Alaska. It is made in a variety of shapes and may be elaborately decorated with fine beadwork.
