Overview

The Hinokuni Aogami Super Kurouchi Gyuto 210mm is a hardworking, no-nonsense wa-gyuto from Kumamoto. Hand-forged with an Aogami Super (Blue Super) carbon steel core and clad in iron with a traditional kurouchi (black) finish, it brings excellent edge retention, bite, and food release in a rugged, rustic package. Expect a confident, slightly thicker spine at the heel that tapers quickly, an agile tip, and a balanced, mid-weight feel—ideal for push cuts through onions, protein trimming, and precise tip work.

Hinokuni pieces are known for their clean heat treatment and practical ergonomics. The oval cherry handle (with black ferrule) offers secure indexing in wet prep, while the ~210–212mm edge length gives you that “just right” 8-inch working zone without feeling bulky. If you’ve wanted “AS steel performance” without a flashy finish, this is it.

Common Questions

Q: Is this knife suitable for home cooks?

A: Absolutely. It’s tough, easy to maintain (for carbon steel), and very rewarding to sharpen. If you’ll wipe it dry during use and after washing, you’ll love the performance upgrade over entry-level stainless knives.

Q: Will it rust?

A: The Aogami Super core is reactive and will form a protective patina over time. Hand-wash only, dry immediately, and store dry. For longer storage, apply a light coat of Tsubaki (camellia) oil.

Q: How do I keep the edge screaming sharp?

A: Touch up on a leather strop—our Tokushu XL Buffalo Strop—between stone sessions. When you want it dialed to perfection, use our Pro Sharpening Service. A soft, knife-friendly board like the Hasegawa Pro will also extend edge life.
