An ulu (Inuktitut syllabics: ᐅᓗ, plural: uluit, English: "woman's knife") is an all-purpose knife traditionally used by Inuit, Yup'ik and Aleut women. It is utilized in applications as diverse as skinning and cleaning animals, cutting a child's hair, cutting food and, if necessary, trimming blocks of snow and ice used to build an igloo.
Today the ulu is still often made with a caribou antler handle but the blade is usually made of steel. The steel is quite often obtained by purchasing a hand saw or wood saw and cutting the blade to the correct shape. A hardwood called sisattaq is also used for handles. These uluit are both kept for home use and sold to others. It is also possible to purchase commercially produced uluit, sometimes made with a plastic handle and complete with a cutting board.
