Compact, precise, and stunningly elegant—the Hado Ko-Bunka SG2 Shiosai Urushi 135 mm is your ultimate Japanese utility knife for everyday prep and professional kitchens. Its hand-forged SG2 powder steel blade is finished with subtle nashiji (hammered) detailing, reducing food adhesion while delivering razor-sharp precision.
BLADE SHAPE:
The Ko-Bunka blends the elegance of a traditional Bunka with the practicality of a Santoku, delivering clean, controlled cuts with every motion. Its distinctive Bunka profile features a sharp Tanto-inspired tip, perfect for herbs, vegetables, and smaller pieces of meat. Compact, precise, and versatile, the Hado Ko-Bunka is a utility knife ready to shine in any kitchen.
*The cutting edge measures 126 mm (heel to tip), but the total blade length from handle to tip is 135 mm.
STEEL:
This Ko-Bunka is made of SG2 powder steel, hardened to around 62-63 HRC. Powder steels are among the hardest steels used in knife making today, which means the knife will keep a smooth and sharp edge for an extremely long time. Thanks to its high chromium (Cr) content, the blade is remarkably easy to maintain. Its steel composition and microstructure allow for an extremely fine, smooth, and long-lasting edge.
LAMINATION:
The blade is san-mai laminated, with outer layers of softer stainless steel that provide additional rust protection.
BLADE FINISH:
Renowned for their elegance and precision, Hado knives feature distinctive tsuchime hammering that fades into a subtly misted migaki finish, highlighting the polished SG2 steel core. Every knife is paired with carefully designed packaging that reflects its craftsmanship.
HANDLE:
The knife features a traditional octagonal wa handle that perfectly complements the balanced blade, offering a secure, comfortable grip and exceptional durability for everyday use.
SMITHY:
Hado is a young yet highly respected Japanese smithy from Sakai, founded in 2019 as a subsidiary of Fukui Co. & Ltd. Blending tradition, innovation, and the founders’ passion for the “path of the blade,” each knife reflects centuries of blacksmithing heritage, masterful handcraft, and modern respect for materials, ergonomics, and design. Hado is synonymous with Japanese precision, minimalist beauty, and pure craftsmanship.
