The kukri was the weapon that the Gurkha forces used in the Anglo-Nepal War as well as in First and Second World War. Nepalis handle these knives from the age of five. Kukris usually have a notch or a pair of adjacent notches at the base of the blade, the "kaura" or "cho", situated near the handle. Various reasons are given for this, both practical and ceremonial: that it can be used to catch the strike of a sword; that it makes blood and sap drop off the blade rather than running onto the handle. The Kukuri knife should be used with care. Because of the angle of the blade, slight force is multiplied many times making this one of the most lethal cutting tools available.
