A steel stone-carving tool, often with a large, brick-like head, having two striking ends, each covered with rows of pyramidal metal points. Found in several sizes, some with a longer, thinner head. Bush hammers are used to dress the surface of a stone by breaking down the rock surface, pounding and removing small amounts at a time. The textures achieved are typical among finishes in traditional French masonry. Granite and other igneous rock are worked with a bush hammer, although now it is usually an electrically motorized version. Also called by its French name, "bouchard" or "boucharde."
Abbreviation for quart.
