Located about 30 km from Cao Bang City, Phuc Sen commune is not only a peaceful village nestled amidst towering mountains, but also a renowned "knife-making village" throughout the Northeast region. For hundreds of years, the people here have been intimately connected to the furnace, iron hammer, and red-hot steel bars, forging sharp, durable knives to serve the production and daily life of the mountain people.

The sound of hammers and anvils echoed crisply in the quiet atmosphere of the knife-making workshop in Phuc Sen. The sound of hammers and anvils echoed crisply in the quiet atmosphere of the knife-making workshop in Phuc Sen.

The craft of knife forging in Phuc Sen is mostly passed down from generation to generation by the Nung An ethnic group. Without modern machinery, everything is done manually with skill and long-accumulated experience. Each knife, sickle, machete, etc., forged is not simply a tool but also embodies the spirit, culture, and pride of the community.

The people of Phuc Sen choose steel from old car springs as their raw material – a "discarded waste product" – but through the diligent hands of their blacksmiths, it is given a new lease of life. The knife-making process involves many meticulous steps: heating, forging, stamping, grinding, and assembling the handle... Each step requires patience, precision, and a keen sense of fire and steel. Some blacksmiths don't need watches or thermometers; they can tell when it's time to forge the knife to achieve the desired hardness and ductility just by looking at the glowing embers.
