The Hado Sumi line is a  hand forged shirogami 2 blade with a rustic style kurouchi finished soft iron cladding. Handle is octagonal burnt oak sealed with a thin clear urushi lacquer coating.

HADO is based in Sakai, Japan, launched in 2019 by Fukui & Co. Ltd. The brand was influenced by Tadataka Maruyama, a former sales and warehouse manager at Fukui & Co., whose passion for craftsmanship led him to train for three years with master sharpeners in Sakai. With the support of company president Motonari Fukui, HADO was created to foster Maruyama’s journey and uphold Sakai's sharpening traditions. Though Maruyama has since pursued his own independent work, his influence remains central to HADO’s approach.

HADO works with some of Sakai’s most respected blacksmiths—including Yoshikazu Tanaka and Satoshi Nakagawa—who forge blades from a number of premium steels as well as high-grade pre-laminated stock. These are then sharpened and finished by HADO’s in-house team, ensuring exceptional craftsmanship in consistent geometry and refined edges.

  • This is a carbon steel knife made from thin, hard steel.
  • Hand wash and towel dry after use. Do not air dry or place in the dishwasher.
  • Expect oxidation (color change, staining, spotting) with use.
  • Prolonged exposure to moisture or food debris will cause rust; remove any rust with a light abrasive.
  • Remove surface rust gently with a mild abrasive and progress to more aggressive abrasives if needed. Coarse abrasives will leave scratches in most finishes.
  • Avoid twisting, scraping, or use on dense or hard foods and surfaces to avoid early dulling and edge damage. If you wouldn't bite into it, don't cut it with this knife.

Shirogami 2 (White Paper #2)

Carbon (C): 1.05–1.15%| Manganese (Mn): 0.2–0.3%| Phosphorus (P/S): trace

White 2 is a slightly lower|carbon variant (~1.05–1.15% C) offering better toughness and ease of sharpening. Common in Japanese kitchen knives, it reaches ~61–63 HRC and provides a clean, crisp edge. It’s reactive but widely loved for its balance between hardness and maintainability.

About HADO

Sakai, Osaka, Japan

HADO is a Sakai-based brand that integrates forging, sharpening, and finishing in-house—rare in a region where these roles are often separate. Founded by former members of Oul Sakai, HADO works with blacksmiths like Yoshikazu Tanaka, Satoshi Nakagawa and Shogo Yamatsuka, while sharpening is led by their in-house grinders. The result is knives with consistent geometry, exceptional edges, and distinctive polish. HADO focuses on clean grinds, comfortable profiles, and high-performance finishes, often using White and Blue carbon steels. By controlling the full process, they offer knives with both artisan quality and a unified design vision.
