The kris or keris is a prized asymmetrical dagger most strongly associated with the culture of Indonesia, but also indigenous to Malaysia, Thailand, Brunei and Singapore. It is known as kalis in the southern Philippines. The kris is famous for its distinctive wavy blade, although many have straight blades as well.
A kris can be divided into three parts: bilah (blade), hulu (hilt), and warangka (sheath). These parts of the kris are objects of art, often carved in meticulous detail and made from various materials: metal, precious or rare types of wood, or gold or ivory. A kris's aesthetic value covers the dhapur (the form and design of the blade, with around 150 variants), the pamor (the pattern of metal alloy decoration on the blade, with around 60 variants), and tangguh referring to the age and origin of a kris. Depending on the quality and historical value of the kris, it can fetch thousands of dollars or even more.
