Keris
The keris (also spelled keris) is the national weapon of Indonesia and the oldest distinctive weapon in that culture. It is found throughout the archipelago, as well as in Malaysia and the Philippines. It was the tool of ancient heroes and kings, becoming a symbol of both courage and beauty. Sultans had elaborate versions of the kris made for them by famous bladesmiths. Keris blades are hammer-welded of special iron, even meteoric iron.
According to legend, Empu Ramadi around A.D. 230 made the first keris. Early kerises were leaf-shaped and were called pasopati, paso or pisau, meaning knife, and pati, meaning deadly. Antique kerises are kept as heirlooms or votive objects, and some are said to possess magic power. The curved blade appeared around A.D. 329. The number of curves is always odd, and the correct number for a particular owner is based on a thumb-beside-thumb measuring ritual accompanied by “lucky” incantations.
The wavy blade or sarpa lumaku (walking serpent) was perfected and began to decline in the 15th century, the last period of “magic” kerises. The pamor (Damascus) blade-welding technique also began to die out after the Majapahit era. Hammer-welding three metal bars containing nickel iron and meteoric iron created the distinctive patterns. This allowed varying degrees of hardness in the blade, combining sharpness with shatter resistance. Rust and even poison were sometimes added to make the blade deadlier.
