Bhutanese Blacksmithing (Garzo)

གར་བཟོ (Garzo)

Garzo (གར་བཟོ — 'iron craft') is Bhutanese blacksmithing — historically producing the full range of iron tools, weapons, and agricultural implements for Bhutanese communities, and still producing the ritual iron objects of Vajrayana Buddhism: the phurba dagger (iron point), the kila spike (ritual peg), and the chandelier-hook for monastery lamps. The defining Bhutanese Garzo tradition is the folded-iron technique for the phurba point: iron is folded 5–7 times during forging to produce a multi-layer blade with alternating hard and soft iron bands — the same structural principle as Japanese nihonto (CRAFT-0472) but at far fewer folds and assessed not by metallurgical knowledge but by the blade's flex response: correct multi-layer iron flexes slightly and returns to straight; single-layer iron does not flex; over-folded iron is brittle.
