An ulu is an Inuit woman's knife. Its blade is formed as a somewhat semi-lunar shape, which is excellent for a variety of tasks, especially scraping skins and preparing food. Prehistoric ulus were made with slate, but the body of the knife was replaced by metal as it became more available through trade relations. Handles are usually made out of bone, wood, or antler. This general purpose cutting tool was the primary implement for skinning pelts, as a chopping instrument, for slicing fish and for cutting out clothes, boots, and mittens.
