[1] Given to Charles Knaud, a Dutch physician, by Paku Alam V in the 19th century, the kris is on display at the Tropenmuseum, Royal Tropical Institute in Amsterdam.

Scientists suspect that due to its special features the kris is even older, but was decorated during the heyday of the Majapahit kingdom to celebrate an important event.

[2] The kris bears scenes from the Ramayana on an unusual thin copper layer which partially covers it.

Long after Knaud's death, during World War II, his family buried the Keris in their garden to protect it during the Japanese occupation.

Kurht Knaud loaned the keris to the Royal Tropical Institute, K.I.T., Amsterdam, where it has been displayed since February 2003.
