Surplus Indian truck steel (suspension leaf spring) are imported from Kolkata (western India) to Dharan (eastern Nepal) and transported to factory located in Chaukibari . The steel is carefully observed for cracks or puncture and then the selected ones are stored with other raw materials. The steel is now weighed to make the required type of khukuri. Initial weight of the steel should be heavier than the actual weight of khukuri as steel loses its weight and also the area becomes smaller during the process of making khukuri.
