"According to legend, Empu Ramadi around A.D. 230 made the first kris. Early krises were leaf-shaped and were called pasopati, paso or pisau, meaning knife, and pati, meaning deadly. Antique krises are kept as heirlooms or votive objects, and some are said to possess magic power. "

I found the above interesting because it is also what I heard, anybody know who Empu Ramadi is. Did some google searches and he is described as the empu of the gods.
