The keris is a weapon from the Javanese tribe which has a variety of cultural functions and many of them have a damascene appearance, namely the visible layers of bright metal fibers on the blade.
In the past, the keris functioned as a weapon in duels or war, as well as a complementary object for offerings. In today's use and the development of the keris from time to time, the Javanese have turned it into an object that has a life teaching philosophy for its owner, as self-identity, a moral message, a symbol of self-reflection, peace, patience, hopes/dreams, as well as a self-reminder or fence. Advice for the owner to always be peaceful and calm and not get emotional easily. Keris are collectible objects that are valued in terms of their aesthetics.
Keris has been registered and recognized by UNESCO as a World Non-Tangible Human Cultural Heritage originating from Indonesia since 2005.
