This is a large and heavy Khukuri. Named the 3 Chirra for it’s 3 wave patterns in the blade. Spine is 3/8 inch thick of forged Carbon steel and 12 inch blade and approximate 800 grams for the knife alone. The knife weight varies as these are hand forged and the fullers (waves) affect the weight quite a bit. Some weigh up to 900 grams .
