Forged in Hirosaki, Japan, this 170mm multi-purpose knife features the innovative VG-XEOS core steel, known for its exceptional balance of hardness, corrosion resistance, and toughness.\nNow available with two distinct configurations, this listing allows you to choose between a cutting-edge Carbon Fiber Wa-Handle for a modern aesthetic or a Blade Only (No Handle) option for custom handle makers and enthusiasts.\nCustom Handle Options\n\n\nCarbon Fiber Wa-Handle: A high-tech twist on the traditional Japanese octagonal handle. This carbon fiber option is incredibly lightweight, impervious to moisture, and provides a sleek, modern balance to the textured blade.\n\nBlade Only (No Handle): Perfect for DIY enthusiasts or professional handle makers. The blade arrives with the tang prepared for a custom fit, allowing you to choose your own wood or resin materials.\n\n\nTechnical Performance &amp; Finish\nThe Tsuchime (hammered) and Damascus finish isn't just for aesthetics; the textured surface creates air pockets that reduce food drag and sticking during precision slicing.
