廓尔喀刀，即库克力弯刀（尼泊尔语：खुकुरी，Kukri），亦称库克力反曲刀，因其刀锋和一般弯刀相反。使他著名的原因是尼泊尔人将其用于战场上战斗，是尼泊尔的国刀。当士兵获得战功后，他们可以被赐予一把刻上了他的名字的廓尔喀刀。相对其他刀种，他是一把长度中等的弯刀。就算不是在战斗的时候也好，日常生活时廓尔喀也都会佩戴在身，作为一个用于切割对象的工具，因此它也是每个尼泊尔家庭不可缺少的东西。当枪械故障不能发射或是子弹用尽时，尼泊尔人便会拔出廓尔喀刀，跟敌军作战，所以廓尔喀刀更是廓尔喀士兵的象征。起初主要使用廓尔喀刀的部落民族只有三个，他们分别是「古隆族」、「马嘉族」及「林布族」。

The kukri Nepali:खुकुरी is a Nepalese knife with an inwardly curved blade, similar to a machete, used as both a tool and as a weapon in Nepal and some neighbouring countries of South Asia. Traditionally it was, and in many cases still is, the basic utility knife of the Nepalese people. It is a characteristic weapon of the Nepalese Army, the Royal Gurkha Rifles of the British army, the Assam Rifles, and Gorkha Regiments (India) of the Indian Army, and of all Gurkha regiments throughout the world, so much so that some English-speakers refer to the weapon as a "Gurkha blade" or "Gurkha knife". The khukuri often appears in Nepalese heraldry and is used in many traditional rituals such as wedding ceremonies.
