The Chinese also made blades from jade. This beautiful mineral is hard but brittle, so the blades are unlikely to have been put to practical use. Instead they would have been held by chieftains as symbols of authority. Large quantities of jade blades have been excavated in different regions in China, indicating their widespread use over a span of more than 3,000 years.","physicalDescription":"Looks like a rectangular tablet, with one hole drilled at the top and two holes along one side.
