Ban Fai Mun village in the district is known for its fine knives. Nan and Phrae Provinces were settled by Tai Phuan people who migrated to northern Thailand in 1834 from Laos. The people of Ban Fai Mun brought with them a distinctive dialect, way of life, and a knife making tradition. About 10% of the population of 1,134 make their living by making knives.[3]
