A furison is a fire steel, used with flint to strike sparks for starting fires. It is also blazoned a “ferris” in mundane heraldry. The furison is a period charge, found in the arms of Grassawer, c.1340 [Zurich 237]; but its most famous usage is as a badge of the Order of the Golden Fleece, c.1430. It is fesswise by default, with its flat edge (its “steel”) to base.
