Product Overview

The MASAHIRO Carbon Professional Western-style Deba 240mm is a powerful, large-format professional knife designed for heavy-duty processing tasks, crafted in Seki City, Gifu Prefecture, Japan’s historic center of blade-making.

This knife combines the strength of a traditional Japanese Deba with the versatility of a Western-style double-bevel edge, making it suitable for breaking down large fish, processing poultry, and handling thick bones with confidence. Compared to smaller models, the 240mm blade offers greater reach and cutting power, ideal for professional kitchens and fish-processing environments.

Forged from pure Japanese carbon steel, the blade delivers exceptional sharpness, a decisive cutting feel, and excellent edge retention. With a hardness of HRC 60, it maintains a durable edge while remaining easy to resharpen—an essential quality for professionals who rely on consistent performance.

The thick 5.0 mm spine and substantial 410 g weight provide stability and momentum during demanding cuts, while the full tang construction ensures strength, balance, and long-term durability.

Finished with a natural rosewood handle, this knife offers a comfortable grip, refined appearance, and the robust feel expected from a professional-grade tool.
