Hado Shiosai SG2 Powdered Stainless 180mm Bunka - Stabilized Wood Handle

Rhythm of the Tide: Hado Shiosai 180mm Bunka

The Hado Shiosai 180mm Bunka is a masterpiece of modern Sakai craftsmanship, designed for chefs who prioritize both structural precision and aesthetic soul. Part of the celebrated Shiosai ("sound of the tide") series, this all-purpose kitchen knife is forged from ultra-premium SG2 (Super Gold 2) Powdered Stainless Steel and brought to an elite hardness of 64 HRC. The result is a surgical cutting edge that retains its aggressive bite significantly longer than traditional stainless cutlery.

The Bunka profile functions as a versatile, profile-forward alternative to a classic Santoku or short Gyuto. Its flatter edge is optimized for clean, effortless push-chopping of vegetable bundles, while the dramatic, clipped K-tip (Sword Tip) grants the user exceptional precision for intricate scoring, coring, and delicate protein trimming.

Engineered Performance: Premium Stabilized Wood

This striking edition updates the traditional Japanese aesthetic with a high-tech Stabilized Wood handle. Through a meticulous vacuum process, natural wood fibers are deeply infused with liquid resins, rendering the handle completely impervious to water, humidity, and kitchen oils. It retains the organic beauty and tactile warmth of natural wood grain while offering industrial-grade durability that will not crack, warp, or split over time.

Technical Specifications

Universal Handling: Left & Right-Handed Friendly

Authorized Hado Dealer

When you purchase from Hasu-Seizo, you are guaranteed an authentic product sourced directly from Hado (Sakai Fukui) in Sakai, Japan. Under the artistic vision of Takaya Oyamada, Hado collaborates with the region's elite smiths and sharpeners to produce kitchen cutlery with unmatched cutting geometry. Every blade is thoroughly inspected at our Seattle area warehouse to ensure it meets our strict standards before it ships to your door.

Sharpening Maintenance

Sharpening Maintenance: SG2 steel is remarkably rewarding to sharpen, but its high hardness requires quality stones. To maintain this blade's surgical edge, we recommend a #1000 Grit Whetstone to start. Then a #6000 Grit Whetstone for finishing which produces a mirror-polished finish that highlights the 'Shiosai' tides of the blade.

Performance & Care

• Best For: All-purpose vegetable preparation, dicing aromatics, mincing garlic, and precision slicing of boneless proteins.
• Care: Hand-wash only with mild soap and a soft cloth; dry immediately. Never put this knife in a dishwasher.
• Safety: Strictly avoid cutting bones, frozen foods, or hard pits. The ultra-fine 64 HRC edge is tuned for flawless slicing and can chip if subjected to high-impact twisting or prying.

Frequently Asked Questions

What is the practical advantage of a 180mm Bunka? The Bunka features a wider blade face than a standard Gyuto, providing great knuckle clearance and letting you easily scoop up chopped ingredients off the board. The flatter profile is exceptional for clean up-and-down chopping motions, making it an incredibly satisfying daily driver for heavy vegetable prep.

How does Stabilized Wood handle the kitchen environment? Natural wood handles can swell when wet and contract when dry, which can eventually cause them to split or break away from the tang. Stabilized wood undergoes a process where all the natural air pockets are replaced with synthetic polymers. It behaves like a durable composite—meaning it is waterproof, stain-proof, and completely low-maintenance.
