Bronze Socketed Adzes and Moulds
Palawan, Tawi-Tawi, and Batangas
Socketed adzes made from bronze are characteristic of the Early Metal Age. Bronze socketed adzes were found in Batu Puti and Uyaw Caves in Palawan; Sanga-Sanga in Tawi-Tawi; and Batangas. These tools were dated from 300 B.C. to 500 B.C. Clay molds for casting these bronze adzes recovered in the caves indicate that the people during that time reused damaged bronze implements for making socketed adzes.
The present implement known as wasay (axe) in central Philippines could have come from the bronze socketed adze of the Early Metal Age.
