Blade Hardness

HRC (Rockwell Hardness) measures how hard the blade's steel is. Kitchen knife steel typically falls in the high-50s to mid-60s on this scale. Harder steel is built to hold a fine edge over long use, while softer steel favors flexibility and easy resharpening. The right HRC depends on the steel and design, not a single higher-is-better number.

Stain Resistant

This steel is not stain resistant. High-carbon steel can rust or develop a patina if not kept dry and cared for, in exchange for the sharper edge it holds.

Saya Cover

This knife comes with its saya cover included at no additional cost, shaped to its exact blade for the same custom fit customers pay extra for on other knives.

Honyaki translates as "true forged" and represents the purest reflection of the traditional art of Japanese sword making. Our master craftsmen use ancient techniques handed down through generations to produce knives of the highest caliber. Each knife is hand-forged from a single piece of high carbon steel, requiring extraordinary skill and precision. Temperatures within the furnace reach into the thousands, ensuring the steel retains its strength and durability.

Forged by legendary master craftsman Ikeda Tatsuo, this one-of-a-kind work of art is finished with the ancient techniques of Japanese sword polishing. Our Yoshihiro Shiroko White Steel #1 Mizu Yaki Water Quenched Honyaki Mirror-Finished Usuba Kama Gata represents the pinnacle of quality in Japanese knives. The Mizu Honyaki method involves pure water quenching, drawing out the hardness of refined steel while infusing it with the resiliency needed for consistent performance under the most demanding conditions. The single piece of White Steel #1 (HRC 66) is heated in hearths that reach extreme temperatures and quenched with the Mizu Honyaki method to ensure exceptional hardness and durability. Polished to a brilliant mirror finish, incandescent wisps of light reflect across the blade's Hamon temper line, a rare and stunning feature that signifies the craftsmanship of a master sword maker.

This beautiful knife is complemented by an Octagonal Ebony wood handle of the highest quality, adorned with a double bolster made of Water Buffalo horn and sterling silver. It comes with a rare, artisan-crafted Saya (protective wooden cover) made from ebony, featuring Chinagashi indentations often seen on samurai sword sheaths.

The Usuba is a traditional Japanese vegetable knife, similar to a small cleaver, designed with a sharp tip for intricate work. Cherished for its ability to chop through root vegetables and thinly slice delicate tomatoes, it elevates every task. Whether you're prepping greens for a salad or chopping vegetables for a main dish, the Usuba transforms simple tasks into artful culinary moments, all with a knife that is as beautiful as it is functional.
