Kris Indonesian sacrificial knife.

A kris is an Indonesian, Malaysian or Philippine dagger double, often wavy blade where mystical powers are attributed to. The crystal is often worn as a sign of authority or dignity. Indonesia is the belief that someone dies soon as one crosses a kris in his footsteps. The mocking of a crystal leads to disaster. If a crystal is made with nickel from the meteorite in 1749 in the area around Prambanan fell, the gun should only be directed at the said person sentenced to death. The crystal is included in the list of masterpieces of the oral and intangible heritage of humanity by UNESCO..
