Karambit

The kerambit or karambit (Minangkabau language: kurambik or karambiak) is a small Southeast Asian hand-held, curved knife resembling a claw. Known as kerambit in its native Indonesian and Malay, it is called karambit in the Philippines.

Origin
The kerambit is believed to have originated among the Minangkabau people of West Sumatra where, according to folklore, it was inspired by the claws of big cats. As with most weapons of the region, it was originally an agricultural implement designed to rake roots, gather threshing and plant rice. As it was weaponised, the blade became more curved to maximise cutting potential. Through Indonesia's trade network and close contact with neighbouring countries, the kerambit was eventually dispersed through what are now Cambodia, Laos, Malaysia, Myanmar, Thailand and the Philippines.

Culturally the kerambit was a subject of condescension in Java because of its history as a weapon of the agrarian peasantry, as opposed to the kesatria (warrior class) who were trained in the keraton or palace. European accounts tell that soldiers in Indonesia were armed with a kris at their waist or back and a spear in their hands, while the kerambit was used as a last resort when the fighter's other weapons were lost in battle. Nevertheless it was popular among women who would tie the weapon into their hair to be used in self-defense. Even today, silat practitioners regard it as a feminine weapon. The renowned Bugis warriors of Sulawesi were famous for their embrace of the kerambit. Today it is one of the main weapons of silat and is commonly used in Filipino martial arts as well.

Superficially the kerambit resembles the jambiyah but there is no connection. The jambiyah was always designed as a weapon and serves as a status marker, often made by skilled artisans and jewelers using precious stones and metals, whereas the kerambit was and still remains an unadorned, modest farmer's implement and useful utility knife.

Technique
The kerambit is held with the blade pointing downward from the bottom of the fist, either curving forwards or backwards. While it is primarily used in a slashing or hooking motion, kerambit with a finger ring are also used in a punching motion hitting the opponent with the finger ring. Some kerambit are designed to be used in a hammering motion. This flexibility of striking methods is what makes it so useful in self-defense situations. The finger guard makes it difficult to disarm and allows the knife to be maneuvered in the fingers without losing one's grip.

The short Filipino karambit has found some favor in the West because such proponents allege the biomechanics of the weapon allow for more powerful cutting strokes and painful "ripping" wounds, and because its usability is hypothesized as more intuitive, though there continues to be debate about this matter.

Variations
There are many regional variants of kerambit. The length of the blade, for example, could vary from one village or blacksmith to another. Some have no finger guard and some feature two blades, one on each side of the handle. Traditional types include:
 * Kuku Bima: Bima's claw from West Java
 * Kuku Hanuman: Hanuman's claw from West Java
 * Kuku Machan: tiger's claw, endemic to Sumatra, Central Java and Madura
 * Kerambit Sumbawa: larger, sturdier kerambit made specially for battle. From the Sumba Islands
 * Kerambit Lombok: larger, sturdier kerambit made specially for battle. From Lombok
 * Lawi Ayam: chicken's claw, created by the Minang community

Additionally, modern kerambit may have spikes or spurs on the front or rear ricasso, which may be intended for gripping clothing or horse tack, tearing flesh or for injecting a poison, such as the upas.

Modern forms
The modern Western interpretation of the kerambit is far removed from the original agricultural tool. They may have folding blades (more dangerous to utilise in agrarian contexts) and finished to very high standard, as opposed to being rudimentary and makeshift. As they are made from expensive materials, the Western variation is beyond the financial means of most South East Asian peasants. They also are generally larger to accommodate larger hands and the sheath is usually made of modern materials rather than wood or leather.

The West has recently found the kerambit to be useful for self-defense. Most of those produced in the West for use as weapons are based on the small Filipino variety, which features a short blade and index finger ring. Both fixed blade (generally double-edged) and folding (generally single-edged) kerambit are produced by a number of makers, including Warren Thomas, Mantis Knives, Emerson Knives, Strider Knives, Spyderco, Cold Steel, Craig Camerer, United Cutlery, Rich Derespina, Cutters Knife and Tool, 5.11 Tactical, Kramer Custom Knives, Tom Ferry Knives, Mike Snody, Quartermaster Knives, Tindle Knife Works, and Fox Cutlery.
