axinomancy

Axinomancy is an obscure method of divination using an axe, hatchet, or (rarely) a saw. Most methods involve throwing an axe into the ground, or swinging it into a tree, and interpreting the direction of the handle or the quivering of the blade. A form of this is axiomancy; this is when the quivering of the blade of an axe that has been thrust into a wooden table is interpreted by the diviner.

Another interesting method is heating an axe-head in a fire until it glows, and then interpreting the colors and shapes. A variant, attributed to the ancient Greeks, who held it in good repute, is to balance a spherical piece of agate on the edge of the axe (held sharp edge up). The direction in which the agate rolls can be interpreted as needed.
