Material Science and Edge Geometry

The Ginsan core is a high-performance alloy containing 13% chromium and 0.95% carbon. At 61 HRC, the edge remains rigid under pressure but retains enough toughness to avoid the micro-chipping common in harder, more brittle steels. The 50/50 double-bevel grind makes this accessible for both left and right-handed professionals, while the hand-finished 3-layer cladding protects the core and reduces surface friction.

Practical Application and Handling

Specifically designed for slicing boneless proteins, the Sujihiki’s low profile reduces the surface area contact between the food and the steel. This prevents 'sticking' when portioning large cuts. The walnut handle is naturally oil-rich, offering better water resistance and durability than lighter woods like Ho wood, making it suitable for heavy commercial use.

Professional Care and Maintenance

• Sharpening: We recommend 1000/6000 grit Japanese waterstones. The Ginsan steel responds quickly to stone work.
• Cleaning: Hand wash only with mild detergent. Dry immediately. Do not leave in a sink or dishwasher.
• Storage: Use a wooden saya (sheath) or a dedicated knife roll to protect the 61 HRC edge from contacting other metal tools.
• Safety: This knife is highly specialized for slicing; avoid contact with bone, frozen foods, or hard pits to prevent edge damage.
