Ask anyone about Nepal's heritage and you'll hear about Pashupatinath, Dharahara or the old Darbar Squares. Rarely mentioned are the people who made those monuments possible: the Kami, Nepal's traditional blacksmiths, whose forges — called aaran — produced the tools, weapons and hardware behind centuries of construction and farming.
Ironworking in the region dates back to the Kirat Period, roughly 800 BCE to 300 CE. It flourished during the Licchavi era, when Kathmandu Valley became a hub for arts and crafts, and by the Malla period (1200-1769) Kami metalworkers were exporting finely crafted pieces to India and Tibet. Alongside the Aagri subgroup, they mined and smelted ore across the country, forged tools for carpenters, masons and farmers, made firearms for soldiers and dies for state mints. Whole communities, in other words, ran on their output.
The aaran itself is more than a workshop. For the Kami it's a shrine where Lord Vishwakarma and other deities are believed to reside. Work begins with prayer, smelting techniques are kept as family secrets, and during Dasain the deities receive offerings. Every year Biswakarma Puja — 17 September this year — sees tools, machinery, even computers and escalators, blessed in the deity's honour. The knowledge involved is genuinely sophisticated: master smiths judged ore quality by sight, managed fuel and bellows to hit precise temperatures, and hardened or softened metal using only water and the colour of the heated iron as a guide.
Yet the craft is dying out. Younger Kami are leaving for other work, pushed by low earnings, a shrinking agrarian economy, cheap imported goods and lingering caste stigma. Each departure means knowledge lost for good. Nepal's government is currently weighing a bill to protect intangible cultural heritage, and the article's author, a PhD scholar at Kathmandu University, argues it should go further: direct financial support to help Kami market their goods, artisan skills built into school and technical curricula, and master smiths recruited as instructors.
There are eye-opening precedents for what these smiths could do. Dalibir Singh Kami of Dailekh built suspension bridges, surveyed highways and repaired typewriters and helicopters in the 1970s. Between 1957 and 1981, Doti's Lal Bd Bishwakarma invented an automated fan, a six-round rifle, a pump that needed no electricity and his own generator. The article contrasts Nepal's neglect with Japan, which honours master metalworkers as 'Preservers of Important Intangible Cultural Properties', and the US, where museums run live blacksmithing workshops celebrating the trade's role in American independence.
For travellers, this reframes what you're looking at in Kathmandu's squares and village watermills: the invisible labour and engineering behind them. And there's a live cultural calendar angle too — if you're in Nepal for Biswakarma Puja, you'll see workshops and tools across the country blessed and garlanded, a rare public moment for a tradition that usually works quietly behind closed doors. Supporting craft workshops and buying directly from remaining smiths is one small way tourism can help keep the anvil ringing.
