This is an ulu whale carving. The ulu is made with a caribou antler handle with fossilized ivory and baleen inlay, and a whale bone blade. The whale is made from baleen and walrus ivory. There are mammoth ivory accents with baleen inlay at the bottom of the ulu. This was made by Alaska Native Inuit artist Jon Ipalook. This is set in a 10" high x 12" wide x 1.5" deep shadowbox.
