Keris is a stabbing weapon belonging to the dagger group originating from Java which has a variety of cultural functions known in the western and central parts of the archipelago. It has a distinctive shape and is easy to distinguish from other sharp weapons because it is not symmetrical at the broad base, often the blade is winding, and many of them have prestige (damascene), which is visible fibers of a bright metallic layer on the blade.
In the past, the keris served as a weapon in a duel or war,[6] as well as a complementary object to offerings. In today's use, the keris is more of an accessory (ageman) in clothing, has a number of cultural symbols, or becomes a collection object that is judged in terms of aesthetics.
