The surface under your knife matters almost as much as the edge itself. Cut on the wrong board long enough and even a freshly sharpened blade will dull faster than it should. That's the problem the Yoshihiro Hi Soft Cutting Board is built to solve: a board designed to go easy on your edge, cut after cut.
What Makes a Cutting Board Good for Your Knife
A cutting board's quality comes down to a handful of practical criteria, and the best boards handle all of them at once:
Edge sympathy: how much the surface gives under a blade. A surface that's too hard rolls and dulls an edge quickly; one that's too soft drags and slows the cut.
Hygiene: resistance to moisture, odor, and bacterial growth, and how easily the surface cleans up after use.
Durability: how well the board holds up to daily knife work without pitting, warping, or scarring deeply enough to become a problem.
Upkeep: what the board actually requires from you — oiling, careful drying, periodic replacement — weighed against what it gives back.
Wood, Plastic, Bamboo, and Rubber/EVA Compared
Wood, especially end-grain wood, is gentle on an edge. It's also demanding: it needs regular oiling and upright drying, and it can hold moisture in ways that invite bacterial growth if care lapses.
Plastic (polyethylene) boards are inexpensive and easy to sanitize when new, but their hardness works against the blade. Over time they develop deep knife scarring that's hard to fully clean, which is why most get replaced every year or two.
Bamboo is often marketed as premium, but it's technically a grass, not a hardwood, and its density makes it one of the harder cutting surfaces available — often tougher on an edge than either real wood or a well-made synthetic board.
Rubber and closed-cell EVA composites aim to combine the edge sympathy of wood with the hygiene and low upkeep of a synthetic surface, without wood's moisture retention or bamboo's hardness. This is the material the Yoshihiro Hi Soft Cutting Board is made from.
What the Hi Soft Board Is Made Of
The Hi Soft Cutting Board is made from closed-cell EVA (ethylene-vinyl acetate), chosen for the balance it strikes between flexibility and durability. The material yields gently under a blade, which helps reduce the edge wear you'd get from a harder surface, while resisting the deep grooving that shortens the working life of a standard plastic board.
Why It's Easier on an Edge
Wood softens the impact on a blade but asks for diligent care to avoid moisture and odor problems. Standard plastic is often harder than people realize, and it wears down an edge steadily with use. The Hi Soft Cutting Board sits between the two: a forgiving surface for the knife, with the hygiene and low maintenance of a synthetic board.
Hygiene
The closed-cell EVA surface resists odor without oils, sealants, or special treatments. Unlike open-grain wood, it doesn't absorb liquid or food particles, which makes cleanup faster and the surface easier to keep sanitary between uses.
Comfort Over Long Prep Sessions
A surface that's easier on the blade tends to be easier on the hand too. The board's slight give can reduce hand and wrist fatigue during long stretches of prep, whether you're breaking down a case of fish for service or working through a big family meal.
Available Sizes
The Yoshihiro Hi Soft Cutting Board comes in a range of sizes, from boards suited to daily home prep to large-format boards for restaurant volume and whole-fish work. See the product page for the current lineup and measurements.
Made in Japan
The Hi Soft Cutting Board is made in Japan and used in professional and upscale sushi kitchens. It's built to complement a good knife rather than work against it — a practical choice for anyone who takes care of their tools.
Care
Hand wash with mild soap and warm water, then let it air dry. Avoid the dishwasher — the heat and prolonged moisture can affect the surface over time. This simple routine is what keeps the board performing well for years of use.
Common Questions
Is an EVA cutting board better than wood? For protecting an edge, closed-cell EVA is comparable to wood's gentleness without wood's moisture retention and upkeep demands — a lower-maintenance option that doesn't ask you to compromise on blade care.
Does it dull a knife faster than other materials? No — its give is what makes it forgiving to an edge, which is why knife-focused kitchens increasingly favor it over hard plastic or bamboo. Like any surface, it will still show wear over years of heavy use.
How should it be cleaned? By hand, with mild soap and warm water, then air dried. Don't put it in the dishwasher.
The Bottom Line
Among wood, plastic, bamboo, and rubber/EVA, the right choice depends on what matters most to your kitchen. If you want edge care, hygiene, and low upkeep without trading one off against the others, closed-cell EVA is a strong option — and the Yoshihiro Hi Soft Cutting Board is built to that standard.
