The term ulu refers to an all-purpose knife traditionally utilized by women among the Inuit, Iñupiat, Yupik, and Aleut peoples. It is a versatile tool used for a wide range of domestic and survival tasks.
Common applications for the ulu include skinning and cleaning animals, cutting food, and trimming blocks of snow or ice to construct igloos. Additionally, it has been used for personal grooming tasks such as cutting a child's hair. Today, these knives are widely sold as souvenirs in Alaska.
