Wire saw + pulley stand + diamond wire rope = Granite stone cut
Mining and quarrying industries commonly use a wire saw to cut hard stone into large blocks that can then be shipped to processing plants to be further refined (in the case of ore dressing) or shipped to distributors (in the case of granite or marble for building). These wire saws are large machines that use diamond-impregnated beads on a cable. The saws allow the bottom of a quarry slab to be cut free (after the cable is passed through access drill holes); with the bottom cut, back and side charges (explosives) can cleanly cleave the slab. Quarry saws on this principle date back centuries; before the era of steel cables with diamond cutters, there were fiber ropes that drew sand through the kerf. The sand (flushed with water) cut the stone (albeit more slowly than diamond does today).
