Hado SG2 Shiosai Urushi Ko Bunka 135mm

Overview

The Hado SG2 Shiosai Urushi Ko Bunka 135mm is a compact Japanese kitchen knife that brings premium Sakai craftsmanship into a highly practical everyday format. With its nimble ko bunka profile, refined hammered finish, and beautifully lacquered urushi oak handle, this knife is built for cooks who want laser-like precision in a smaller blade. It is especially useful for shallots, garlic, herbs, small fruits, detail vegetable work, and in-hand prep where a full-size bunka or gyuto can feel oversized.

The SG2 powdered stainless steel core gives this knife a strong mix of edge retention, corrosion resistance, and fine-grained cutting feel. In plain terms, that means it stays sharp for a long time, takes a keen edge, and is easier to live with than a reactive carbon steel knife. The stainless cladding and tsuchime finish also help make the knife more forgiving in busy kitchens while preserving the crisp, high-end feel collectors expect from Hado.

For home cooks, this is the kind of knife that quickly becomes a favorite because it feels fast, controlled, and easy to reach for. For enthusiasts, it offers the clean grind, elegant fit and finish, and premium handle treatment that make the Hado Shiosai line stand out. If you want a small Japanese knife that feels luxurious but still earns its place on the board every day, this ko bunka is a strong choice.

Common Questions

Q: What is a ko bunka used for?

A: A ko bunka is a small bunka-style knife designed for precise prep. This 135mm size is ideal for trimming produce, slicing herbs, mincing aromatics, cutting small proteins, and doing quick board work when a larger knife feels unnecessary.

Q: Is this knife suitable for home cooks?

A: Yes. This is an excellent choice for home cooks who want a premium Japanese knife that is compact, easy to control, and low-maintenance compared with carbon steel. The SG2 stainless core resists rust, holds an edge very well, and performs beautifully in everyday cooking.

Q: How do I care for a high-end Japanese SG2 knife?

A: Hand wash only, dry promptly, and avoid hard twisting cuts or frozen foods. Use a knife-friendly surface like a Hasegawa Pro Cutting Board to help preserve the edge. For routine maintenance, a few light passes on a leather strop can help extend sharpness between sharpenings. If you want to protect the blade during storage, a light coat of tsubaki oil is a smart finishing touch.
