Tosa Sperm Whale Knife

A Distinctive Blade With Purpose

With a fuller presence and stable balance, this knife feels especially reassuring in hand during extended prep sessions.

The Kujira knife is defined by its gently curved blade, a shape developed to support smooth slicing and precise control. The curve allows the knife to glide through ingredients with minimal resistance, making it well suited for vegetables, proteins, and detailed prep work.

This form is as practical as it is recognizable.

Forged From Carbon Steel for Sharpness and Control

Crafted from carbon steel, the blade achieves a level of sharpness that stainless steel cannot easily replicate. It sharpens cleanly, responds well to regular maintenance, and rewards careful use with long-lasting performance.

With time, the steel develops a patina—an honest record of use rather than a flaw.

Balanced for Confident Handling

The knife is designed to feel steady and secure in the hand. Its balance supports controlled movements, allowing you to work efficiently without strain. Whether slicing or trimming, the blade responds predictably and smoothly.
