HO-AI-210 AI Deba – the power of precision in a luxurious Kasumi expression

The HO-AI-210 from the prestigious HO series perfectly embodies the Japanese philosophy of balance between power and finesse. The AI Deba (相出刃) was created for those who expect more than a single function from a knife—this is a tool for conscious chefs who demand control, delicacy, and confidence in one blade.

The HO series is crafted in Sakai, the legendary birthplace of Japanese bladesmithing, using the traditional Kasumi technique. A core of high-carbon YASUKI White #2 steel, clad in soft low-carbon steel, delivers exceptional sharpness, stability, and ease of sharpening. This construction is precisely why HO knives are chosen by professionals and collectors—those who recognize quality without compromise.

AI Deba differs from a classic Deba with a thinner, more sensitive blade, while retaining the single-bevel kataba grind. The Japanese word “Ai” means “both”—and that’s exactly what this model offers: flawless filleting and precise slicing of fish, without sacrificing control during heavier tasks. It’s a knife that moves with intuition, allowing you to literally feel bone structure beneath the edge.

The distinctly tapered spine gives the tip remarkable sensitivity and precision—ideal for filleting and working close to bones—while the solid, heavier heel provides confidence when splitting fish heads, cartilage, or crab shells (with proper technique). Balance biased toward the heel makes the knife surprisingly agile and stable, even during extended sessions.

Completing the experience is a traditional D-shaped handle made from magnolia wood and reinforced with water buffalo horn. This is more than aesthetics—it’s ergonomics refined over generations, ensuring the knife settles naturally in the hand and delivers absolute control.

The HO-AI-210 is for those who:

• want one knife for precision filleting and refined fish work,

• value handcrafted heritage, history, and authenticity,

• see a knife not as a tool, but as an extension of their skill.

This knife doesn’t shout.
It performs—and its presence in the kitchen speaks for itself.

The HO Kasumi series is not mass-produced. It’s a deliberate choice, a symbol of experience and respect for Japanese culinary tradition.
