The Bunka knife is a versatile Japanese kitchen tool, featuring a distinct k-tip (kiritsuke-style) point that excels at precision slicing, chopping, and intricate cuts. Its slightly flatter blade profile makes it ideal for push-cutting techniques, while the sharp tip handles detailed work with ease, making it a perfect all-purpose knife for professional chefs and home cooks alike.

Traditionally, Bunka knives were common in Japanese households before the Santoku rose in popularity. Today, they are celebrated for their versatility, bold aesthetics, and precise performance, offering a stylish and functional alternative to standard chef knives.

The HADO Shiosai line reflects the spirit of tamashii (魂, soul), representing craftsmanship with intention. “Shiosai,” meaning “the sound of the tide”, is captured through geometric tsuchime hammering, a soft kasumi finish, and a polished edge, evoking sunlight sparkling on ocean waves—a beautiful blend of form and function.

This Bunka knife is crafted with SPG2 (Super Gold 2) high-carbon, high-alloy stainless steel and stainless tsuchime cladding, refined via powder metallurgy to ensure a fine grain structure, exceptional edge retention, and effortless sharpening.

The urushi-lacquered oak handle provides superior balance, comfort, and a luxurious tactile experience, making the knife as enjoyable to hold as it is to use.

Each blade is meticulously sharpened by master artisans Tadataka Maruyama, Naohiro Nomura, and Takafumi Tsuda, guaranteeing unparalleled precision and performance. The HADO Shiosai Bunka is a premium Japanese knife designed for chefs who demand both beauty and functionality in their kitchen tools.

Composition of SPG2 (Super Gold 2) Steel

  • Carbon (C): 1.25–1.45% (Enhances hardness and edge retention)
  • Chromium (Cr): 14–16% (Provides corrosion resistance and wear resistance)
  • Molybdenum (Mo): 2–3% (Improves toughness and enhances resistance to pitting and corrosion)
  • Vanadium (V): 1.8–2.2% (Contributes to grain refinement, edge retention, and wear resistance)
  • Manganese (Mn): 0.40% (Enhances strength and hardenability)
  • Silicon (Si): 0.50% (Adds toughness and improves overall durability)

Key Features of SG2 Steel:

  • Powder metallurgy construction results in a fine, uniform grain structure, making it extremely sharp and easy to maintain.
  • High hardness (HRC 62-64) offers exceptional edge retention.
  • Excellent corrosion resistance, making it a great choice for kitchen knives.
  • Tougher than many other high-hardness steels, reducing chipping risk.

SG2 is a premium stainless steel, often used in high-end Japanese knives for its outstanding balance of sharpness, durability, and ease of maintenance.
