The kris typically has a wavy blade. It is an essential part of numerous ritual activities in Java, and also in other Malay-Indonesian cultures.
krises are often lavishly decorated, so they are also works of art.
The word kris itself comes from an Old Javanese word that means “to cut.”
From Candi Sukuh, we can see that the kris was already important in Java, and most likely elsewhere, as a ritual implement by the 15th century.
