Hatsukokoro Blue #2 Kurouchi Bunka 190mm

Overview

The Hatsukokoro Blue #2 Kurouchi Bunka 190mm from the same Tosa-made series is an easy knife to like if you want a carbon steel workhorse with a little more length and versatility than a standard bunka. That extra blade length gives it a broader comfort zone in the kitchen. It still feels nimble and precise, but it has a bit more reach for larger vegetables, longer draw cuts, and more all-purpose prep. For cooks who like the bunka profile but want something that stretches closer toward gyuto territory, this is a very smart middle ground.

At its core is Blue #2 carbon steel, a classic choice for users who want strong edge retention, excellent sharpenability, and the satisfying feel of a reactive carbon blade. The kurouchi finish keeps the look rustic and traditional, and it fits the spirit of Tosa knife making well: practical performance, honest materials, and excellent value over refined cosmetic perfection. That is a big part of why this series makes such a strong recommendation for someone looking for a dependable starter carbon steel knife or a budget-friendly daily workhorse.

In use, this longer bunka works beautifully for vegetables, herbs, onions, garlic, boneless proteins, and general prep. The pointed k-tip gives you fine control for detail work, while the added length makes it more versatile than many compact bunkas. If you are asking, “What if I want a bunka, but I do not want to feel limited by a shorter blade?” this is exactly the kind of knife that answers that question well. Use it on a soft cutting surface like a Hasegawa Pro Cutting Board, hand wash only, and dry it promptly after use.
