There were other uses of obsidian, too. Mesoamericans made a unique weapon called the "macuahuitl." A wooden paddle studded with obsidian blades, it looked like an elongated mace, and surely inspired as much terror. Artisans have used it to make jet black jewelry for at least 10,000 years. And humans have assigned the stone various magical, spiritual, and healing properties throughout history. Apache tears, for example, is a name for rounded obsidian pebbles that are said to have formed from the tears of Native American women mourning Apache warriors killed by the U.S. Calvary. Today, those little rocks are used as meditation stones. Thin volcanic glass fibers called Pele's hair, meanwhile, are named for the volcanic goddess who created the Hawaiian Islands. It's too fragile and sharp to be handled, but remains a potent reminder of the origins of the Polynesian archipelago.
