SE-DE-210 Deba bōchō — Raw Power of Craftsmanship. Precision Without Compromise

The SE-DE-210 from the elite MAC SE series is a manifestation of the primal strength of the Japanese kitchen knife—a tool created for work where precision must coexist with mass, stability, and absolute trust in the blade. This is a knife for those who understand that true craftsmanship is not always subtle; sometimes it must be uncompromisingly effective.

Each piece is handcrafted in Sakai through a process that takes months and demands master-level experience and total control over the steel. The blade is forged using the prestigious Honyaki technique from solid Yasuki Shirogami (White Steel)—a legendary material that is demanding and unforgiving of mistakes. Known for its exceptional structural purity, this steel can achieve extreme sharpness and responds perfectly to differential hardening. In the SE series, there is no room for compromise—any deviation results in the blade being rejected.

Differential hardening gives the Deba its distinctive character: an extremely hard cutting edge combined with a massive, stable blade body. This balance allows heavy-duty tasks to be performed with full control, without sacrificing refined cutting performance or risking unpredictable blade behavior.

The Kasumi finish is the result of prolonged, meticulous hand polishing with water stones. It gives the blade a noble, milky, mist-like surface that subtly contrasts with the raw, powerful nature of the Deba. This finish is not decorative—it is a mark of master craftsmanship, instantly recognizable to professionals and collectors.

The SE-DE-210 is a Deba bōchō (出刃包丁)—a knife with a thick, heavy blade, single-bevel sharpened in the kataba style. Unlike slender slicing knives, the Deba is designed for working with whole fish: cleaning, removing heads and tails, filleting, and working through cartilage and small bones. With proper technique, the Deba can also be safely used to split and crack crab legs and claws.

The first Deba knives appeared during the Edo period in Sakai Prefecture and have remained a cornerstone of Japanese fish cuisine ever since. The traditional Hon-deba was used not only for fish, but also for breaking down poultry and meats with small bones. The substantial weight of the blade is an advantage here—when used with care, the solid heel of the knife can be employed to cut through bones found in small to medium fish and poultry.

The spine of the Deba tapers significantly toward the tip, resulting in a surprisingly thin and sensitive point. This allows the user to feel precisely when the blade is contacting bone—an essential quality when filleting. The combination of a powerful heel and a precise tip makes the Deba far more agile than its weight might suggest.

Balance concentrated near the heel of the blade, combined with a solid handle, gives a strong sense of control. The SE-DE-210 can be brutally effective in heavy tasks, yet unexpectedly precise when more delicate work is required.

Because Japanese cuisine works with many different sizes and species of fish and seafood, Deba knives exist in numerous forms and sizes, including Mioroshi Deba, Ai-deba, and Ko-deba. The SE-DE-210 represents the classic, most versatile form—designed for professional use, without compromise and without pretending to be an all-purpose tool.

The SE-DE-210 is not a knife chosen casually.
It is a tool of responsibility—for chefs who understand that power in the kitchen must go hand in hand with control, and that true luxury reveals itself when a tool never fails.
