Keris daggers, used as deadly weapons centuries ago, are now collector's items and heirlooms in Indonesia passed down from generation to generation. Believed to have magical powers, these daggers are forged by empus, masters of their craft, and some take months to complete because of the rituals and time-consuming steps involved. But the number of empus in the country is dwindling, and the government is trying to get more young people involved in the dying art form. A new keris culture study program was established at the Indonesian Institute of the Arts, Surakarta, and one of the country's most famous empus, Subandi Suponingrat, was recruited to help train new recruits — including his own son.
