Product Description

The Yoshihiro Hongasumi Blue Steel Deba Filet Japanese Knife is forged from High Carbon Blue Steel #2 with a HRC of 63-64, offering exceptional edge retention and the ability to achieve a finer edge compared to the Kasumi Deba made from White Steel #2. This knife is perfect for intermediate-level chefs and is ready to use right out of the box. It includes a Magnolia wood sheath, knife oil, and a rust eraser to maintain the blade’s performance and appearance. Handcrafted with precision in Japan, it’s not mass-produced, ensuring a unique, high-quality blade.

Designed specifically for carving and filleting fish, the Yoshihiro Hongasumi Blue Steel Deba Filet Knife also excels at cutting through some meats. The heavy, single-edged blade effortlessly slices through fish flesh and meat. The Hongasumi forging technique—layering softer steel over a hard steel core—provides superior sharpness, edge retention, and durability. The Blue Steel #2 core delivers a razor-sharp edge, while the softer surrounding iron adds resilience to the blade.

Crafted using traditional techniques, the Yoshihiro Hongasumi Blue Steel Deba Knife features a completely flat ground front (shinogi) and a concave ground (urasuki) with a flat rim (uraoshi) on the back. The octagonal handle, made of Shitan Rosewood, complements the blade perfectly, offering comfort and control during use.

As with all traditional Japanese knives, sharpening and honing should be done using high-quality Japanese water stones. Hand wash and dry immediately after use, particularly when working with acidic ingredients, to preserve the blade. This knife is specifically designed for boneless fish flesh and is not recommended for cutting through bones.
