Janbiya, also spelled jambia, jambya, jambiya, and janbia (Arabic: جنۢبية janbīyah), is the Arabic term for a specific type of dagger with a short curved blade with a medial ridge that originated from Yemen. It is most closely associated with the people of Yemen and Najran in Saudi Arabia. Men typically above the age of 14 wear it as an accessory to their clothing. The janbiya is commonly referred to in Oman as a khanjar, xencer in Kurdistan region.

Types

Ottoman jambiya (hancer), walrus ivory hilt, damascus steel blade, spiral stitched velvet covered scabbard, 19th century.

Janbiya were taken by travelers to other cultures including Persia, the Ottoman empire, and India, where they were adopted with slight differences to the blade, hilt and scabbard.

Hilt or handle

A significant part of a janbiya is its hilt (handle). The saifani hilt is made of rhinoceros horn, which can cost up to $1500 per kilogram. It is used on the daggers of wealthier citizens. Different versions of saifani hilts can be distinguished by their colour. Other janbiya hilts are made of different types of horn, wood, metal and ivory from elephants and walrus. Apart from the material used for the hilt, the design and detail is a measure of its value and the status of its owner.

Blade, sheath and belt

The double edged blade of the janbiya is constructed of steel which in some cases is damascus or wootz steel. The blade is stored in a sheath known as 'Asib (Arabic: العسيب), usually made of wood covered with metal or cloth. The sheath can be decorated with various ornaments that signify status. These include silver work, semi-precious stones, and leather. The sheath can be fixed to a leather belt, which is normally 2–3 inches wide. The belt is usually worn around the lower abdomen. There are often other items attached to this belt, such as a silver purse for containing money and change.

Use

Despite the cultural significance of the janbiya, it is still a weapon. Although people have used it in times of dispute, there are societal and Islamic norms that must be followed in order to avoid defamation. The janbiya should only come out of its sheath in extreme cases of conflict. It is also commonly used in traditional events, such as dances.

Like with some other curved knives, as the blade bends towards the opponent, the user need not angle the wrist, which makes it more comfortable as a stabbing weapon than straight-bladed knives. Its heavy blade enables the user to inflict deep wounds and to cut through muscle and bone. It also makes it possible to cut and twist the blade upwards, slitting internal organs such as intestines, or to reach heart, lungs or liver more easily, making it a formidable and much feared weapon, whose use is thus restricted by societal rules.

Janbiya from Yemen

A jambia is a short dagger worn by men in Yemen. The handle of a janbiya tells the status of the man who wears it.

Structure and make

The janbia was given its name because it is worn on the side of a person – the word janbia is derived from the Arabic word "janb" which mean "side". A janbia is constituted of a handle, a blade, and a sheath in which the blade is held. It is made of a certain sort of wood, to hold the blade that is fixed to the waist from underneath with an upward curved sheath. The belt that holds the janbia is made of tanned leather, or some thick cloth. There are specialised markets and handicraft markets that decorate it with golden wires.

The janbia handle often tells of the social status of the man who wears it. Janbias were often made with ivory handles. The manufacturers most often receive this material through smugglers, due to the international ban on the substance. As ivory has only ever had ornamental merit in such an application, those that recognize the janbia as a tool and/or weapon tend to prefer a hardwood handle anyway. Many street-side charlatans will proclaim to sell ivory-handled janbias whilst actually selling poorly-made blades with white plastic handles.

Qualities

The most famous sort of the janbia is that which has a "saifani" or ivory handle. It has a dim yellowish lustre. The more translucent ivory will turn a yellow colour with age. This is called "saifani heart". Some of the ivory handles are called "asadi", when they turn into greenish yellow. When the handle becomes whitish yellow, it is called "zaraf". There is also an albasali (onionish), kind whose colour resembles that of a white onion.

The ivory handle janbia is often worn as a sign of high social status. They are typically used by most of the Yemeni people, except the people in Aden city where most of them have given up using it. The Janbiya hasn't been specialized for a particular person in the country, but the valuable ones can be found with a particular persons, like judges, famous merchants and businessmen.

Antique janbias that have been worn by historic persons can fetch exorbitant prices.
