Choosing the Right Cutting Board
The Relationship Between a Knife and a Cutting Board
In Japan, there is a saying that a knife and its cutting board are like a married couple—they perform best when they complement one another.
While considerable care is often taken in choosing a Japanese knife, the surface beneath it can easily be overlooked. Yet from the perspective of a professional Japanese knife sharpener, the cutting board is an essential part of how a knife performs and how well its edge is preserved.
After all, every cut ends with the edge meeting the board.
A remarkable example of this philosophy can be found in Shirakiya of Kyoto, a traditional maker of wooden cutting boards. A single board can take around ten years to complete. The timber is seasoned and rested over many years, allowing its natural movement and warping to emerge before it is repeatedly adjusted, shaped, and ultimately finished. This patient process helps stabilize the wood and minimize distortion during years of use.
It reflects a deeper principle of Japanese knife culture: a cutting board is not merely a work surface, but a partner to the blade.
Over hundreds and thousands of cuts, this relationship between blade and board matters. The surface beneath the knife influences edge retention, cutting feel, sharpening intervals, and ultimately the working life of the blade.
Even the finest handcrafted Japanese knife cannot perform at its best when continually used against an unsuitable surface. This is why experienced Japanese chefs and professional sharpeners pay attention not only to the knife in their hands, but also to what lies beneath it.
The Cutting Board Is Part of the Knife System
This understanding has deep roots in Japanese culinary culture.
Even the traditional Japanese word itamae—commonly associated today with highly skilled Japanese and sushi chefs—literally refers to the person who stands “in front of the board.” The cutting board has historically been at the very center of the professional Japanese kitchen.
That relationship continues today.
In serious Japanese kitchens, particularly in sushi and traditional Japanese cuisine where extremely fine edges and precise knife work are essential, the choice of cutting board is not simply a matter of convenience. Chefs consider the way the surface receives the blade, its stability during cutting, hygiene, resistance to warping, ease of maintenance, and the effect it has on the knife over many hours of daily work.
This is why carefully selected woods such as hinoki and hiba have long been valued in Japanese kitchens, while modern professional kitchens also use specially engineered synthetic and rubber cutting boards designed to combine hygiene and durability with a softer, more forgiving contact with the knife edge.
One particularly well-known example is Parker Asahi’s synthetic-rubber cutting board, made from a unique blend of rubber and wood powder, which has been used by legendary sushi master Jiro Ono at Tokyo’s renowned Sukiyabashi Jiro.
It is said that the restaurant continued using the same Parker Asahi cutting board for more than 40 years—a remarkable example of the longevity and reliability expected from professional Japanese kitchen tools.
The story illustrates an important principle: at the highest levels of Japanese cuisine, attention is not limited to the quality of the knife. The surface that receives that knife, day after day and year after year, matters just as much.
Not All Cutting Boards Are Created Equal
Many hardwood boards commonly found outside Japan are exceptionally hard. While they may be beautiful and durable, hardness alone does not make a good cutting board for a fine Japanese knife.
A surface that is too hard repeatedly sends the impact of each cut back into the very thin cutting edge. Over time, this can accelerate edge wear and increase the frequency of sharpening.
The same principle applies to hard plastic surfaces. They may be practical from the standpoint of cleaning and durability, but some are considerably less forgiving to a fine edge than materials specifically selected or engineered to balance hygiene, durability, stability, and edge protection.
Wood requires careful selection as well.
A good wooden cutting board is not simply a piece of wood cut to size. The species, grain, drying and seasoning of the timber, construction, thickness, and long-term dimensional stability all matter.
Poorly prepared wood can warp or distort as moisture changes. Once the cutting surface is no longer flat, the problem extends beyond appearance: the board becomes less stable, cutting becomes less consistent, and precise knife work becomes more difficult.
Why Professionals Care
For a professional chef, these small differences accumulate.
A chef may make thousands of knife movements during preparation and service. A slightly more forgiving surface can reduce unnecessary stress on the edge. A stable, properly maintained board contributes to more controlled knife work. And a surface that is easy to clean, dry and maintain becomes part of an efficient professional workflow.
For sushi chefs in particular, where clean slicing and extremely refined edges are fundamental to the craft, the relationship between knife and board becomes especially apparent.
The knife, the sharpening, the cutting technique and the cutting surface are not independent elements. They work as a system.
A beautifully sharpened knife used on the wrong surface will lose part of the advantage created by that sharpening. Conversely, the right cutting board allows the characteristics of a fine Japanese blade—its sharpness, precision and cutting feel—to be appreciated for longer.
The Yamani Philosophy
At Yamani, we therefore believe that a cutting board should do more than simply provide a surface for food preparation.
It should protect the craftsmanship of the knife, preserve its cutting performance, provide a stable and comfortable working surface, and contribute to the pleasure and precision of cooking.
This is why we approach cutting boards with the same philosophy we apply when selecting Japanese knives.
We do not select them simply for appearance, material, or reputation. We consider how the board actually interacts with the blade, how it performs over time, how it can be maintained, and whether the knife and board make sense together.
Because choosing a fine Japanese knife is only half of the equation.
A great knife deserves the right partner.
