Made this ulu out of some green jasper from Mt. St Helens. The handle is from some Northwest Territories caribou and the ivory but cap came from a Hippo tooth. The blade in the atlatl dart is one someone gave me at the Classic years ago. I spent last Sat. with the Wyo. Game and Fish at one of Wyo's picture graft sites teaching young people to make and throw atlatl darts. Last year it was elk calling and the year before was knapping. Thanks for looking! Joe
