The Tosa Hot Forged Shirogami Bunka 170mm by Yamashin is a strikingly versatile Japanese kitchen knife, hand-forged in Tosa, Japan using time-honoured blacksmithing traditions. Known for its distinctive k-tip (kiritsuke-style) point, the Bunka combines the versatility of a Santoku with added precision for fine tip work and detailed cuts.

Forged from high-quality Shirogami (White Paper) carbon steel, the blade delivers razor-sharp performance, excellent edge retention, and effortless sharpening. The traditional kurouchi (blacksmith) finish gives each knife a unique, rustic appearance while providing light protection against oxidation.

The walnut handle offers a natural, balanced feel, paired with a pakkawood ferrule for durability and moisture resistance. With its 170mm blade, this Bunka is perfect for all-purpose kitchen tasks — from slicing vegetables and proteins to precise tip work on herbs and garnishes
