Masakage Zero Ko Bunka
The Ko Bunka is a compact yet powerful version of the Bunka knife. And yes, “Ko” in Japanese means “small”! Despite its size, this knife offers excellent knuckle clearance on the cutting board, making it perfect for mincing garlic and chopping vegetables. As a hybrid between the Bunka and Petty knives, it excels at smaller, in-hand tasks and serves as a versatile, all-purpose blade in any kitchen.
About the Masakage Zero Line
The Masakage Zero line represents the pinnacle of high-performance craftsmanship, combining razor-sharp precision with standout aesthetics. These knives turn heads, featuring an Ironwood handle (one of the hardest woods on the planet), adorned with a chrysanthemum-shaped mosaic pin. The Masakage Zero truly rivals any knife on the market.
Aogami Super Steel is the king of knife steel. Known for being easy to sharpen, achieving a laser-sharp edge, and offering durability, it lives up to its “Super” name. The outer cladding is stainless steel, which makes this knife easier to maintain while preserving the sharpness and strength of the carbon core.
