SE-FK-270 Yanagiba — Subtle Precision of a Masterfully Crafted Blade

The SE-FK-270 from the elite MAC SE series is the essence of Japanese craftsmanship expressed through a perfectly balanced blade. It is a knife created for those who value absolute control, tactile feedback, and precision of movement—without relying on sheer length. Each piece is handcrafted in Sakai through a process that takes months and demands total mastery of the steel and the quiet patience of a craftsman who understands that true quality is born from focus and restraint.

The blade is forged using the prestigious Honyaki technique from solid Yasuki Shirogami (White Steel)—a legendary, uncompromising, and demanding material. Renowned for its exceptional structural purity, this steel can achieve extreme sharpness and responds perfectly to differential hardening. Every stage of forging, heat treatment, and finishing must be executed flawlessly; even the slightest mistake means the blade is rejected. This is why the SE series is produced in very limited quantities.

Differential hardening gives the blade its distinctive character: an exceptionally hard, razor-sharp cutting edge paired with controlled flexibility along the spine. The result is refined cutting performance, stability in use, and durability that maintains its qualities even under intensive professional conditions.

The Kasumi finish is achieved through prolonged, meticulous hand polishing with water stones. It gives the blade a silky, milky, mist-like surface that subtly emphasizes the blade line and the steel’s structure. This finish is instantly recognizable among masters and collectors—not as decoration, but as a mark of the highest level of craftsmanship and a conscious choice.

The SE-FK-270 is a Yanagi-ba-bōchō (柳刃包丁)—the classic knife of sushi masters, single-bevel sharpened in the kataba style. Its long, narrow blade is designed for absolute purity and control of the cut. Yanagiba knives are used primarily for preparing sushi and sashimi, where the precision of a single motion determines the flavor, texture, and visual elegance of the dish.

Yanagiba knives are mainly used for slicing boneless fish fillets for sashimi and sushi, but they also excel at filleting small to medium fish and removing skin. The slender blade geometry and very acute edge angle significantly reduce resistance during cutting, allowing the knife to glide smoothly, effortlessly, and without damaging the structure of the ingredient.

As with Sujihiki knives, the length of the Yanagiba blade enables a single, uninterrupted cut—from heel to tip. The combination of proper technique, single-bevel geometry, and perfect sharpness results in minimal cellular damage along the cut surface. This is crucial for dishes in which fish is served raw, as it preserves the natural flavor, texture, and sheen of the fish.

The name Yanagiba translates as “willow-leaf blade,” a description that perfectly captures the knife’s long, slender, and elegant silhouette. This classic form originates from the Kansai region of Japan and has remained the gold standard among sushi masters for decades. While many regional variations of Yanagiba exist, the willow-leaf shape is the most widely chosen by professionals.

Yanagiba knives are produced in blade lengths ranging from 210 mm to 360 mm, with 270 mm offering an exceptional balance of precision, control, and agility. The SE-FK-270 is an ideal choice for chefs who value maximum sensitivity and control, as well as for advanced enthusiasts and collectors. A left-handed version is available, made to order with the same uncompromising standards of quality.

The SE-FK-270 is not a knife for everyone.
It is a tool of conscious choice—for those who understand that true precision does not depend on size, and that luxury resides in detail, balance, and flawless blade control.
