Each UL448-001 handle is a singular work of art, born from the earth and shaped by the hands of master artisans. The process of creating Nambu-Tetsu is steeped in tradition, involving intricate sand molds and the precise pouring of molten iron, resulting in a unique, organic texture that is impossible to replicate by machine. Its distinctive, finely pitted surface tells a silent story of its origins, inviting a tactile exploration that few materials can offer. The handle then undergoes a traditional baked finish, imparting a deep, resonant black color that is not merely applied, but intrinsically woven into the iron itself, creating a durable and visually stunning matte surface.
