In 1767 Prithwi Narayan Shah, King of the independent Kingdom of Gorkha to the west of Kathmandu Valley invaded that valley and despite facing numerically superior forces, succeeded in conquering them. Kathmandu fell on 29 September 1768 and thus he became the first King of Nepal.
When he invaded the valley, his troops encountered soldiers armed with traditional edged weapons such as swords, spears and daggers. His own troops carried a comparatively new weapon; a short oddly curved knife and the inability of his enemies to develop a parry for this knife known as the kukri was, in some measure at least, responsible for their defeat. As long as edged weapons continued as the principal weapon of soldiers, the kukri remained superior in hand to hand conflict. Even today the kukri in the hands of an expert remains practically unparryable by sword, sabre or rapier.
The kukri, regarded as traditional to all hill tribes of Nepal, is both a formidable weapon and a tool which has innumerable uses from shaping timber to chopping up meat and vegetables. The blade is of tempered steel, slightly curved and exceedingly sharp. The handle is usually of wood or buffalo horn. A nick in the blade close to the handle serves the purpose of preventing blood from reaching the handle and is also symbolic of the Hindu Trinity of Bramah, Vishnu and Shiva. The blade is enclosed in a scabbard of wood and leather and the whole weapon is some sixteen to eighteen inches long.
Two small knives are found at the top of the scabbard, one blunt (Chakmak) and the other sharp (Karda). The correct use of the former is for starting a fire with a flint stone, and the latter is for skinning or general purpose use.
Gurkhas have used kukris throughout their entire service in the British Army and it continues to be worn with both ceremonial and field forms of dress.
