SO-70  — Refined Flexibility and Masterful Filleting Control

Professional Japanese MAC knives have long set the benchmark for quality in the culinary world, earning the trust of chefs worldwide through their reliability, precision and meticulously refined finishing. At the heart of this esteemed lineup stands the PROFESSIONAL series — a collection designed for intensive, high-performance kitchen environments where every detail, every motion and every cut must be executed with absolute control. The SO-70 is a specialized fillet knife that perfectly reflects the mastery of Japanese culinary tool design.

Its most distinctive feature is the flexible, slender blade engineered for tasks where rigid knives may damage delicate ingredients or compromise precision. The resilient blade effortlessly follows the natural contours of bones, skin and muscle fibers, allowing for clean, accurate separation of fish skin and precise filleting of even the most demanding cuts. It is a tool created for delicate, controlled and highly refined work.

The high-grade steel used in MAC knives ensures exceptional sharpness, resistance to staining and consistent cutting performance over long periods of intensive use. This allows the blade to maintain flawless efficiency not only when filleting fish and meat, but also during precise preparation of fruits and vegetables, where finesse and accuracy are essential.

The handle, crafted from durable PAKKA wood — a carefully engineered fusion of natural wood and resin — provides excellent moisture resistance, a secure grip and superior comfort even during prolonged use. With a total length of 305 mm and a weight of approximately 100 g, the knife offers outstanding balance and effortless handling, enabling smooth, stable and intuitive control while reducing hand fatigue and enhancing precision with every movement.

The SO-70 is a refined culinary instrument that performs exceptionally well in professional restaurant kitchens as well as in the hands of dedicated home cooks who value precision and control. Its versatility extends beyond fish and meat filleting to include delicate work with fruits and vegetables, delivering fluid cuts and aesthetically refined ingredient preparation.

The blade’s high stain resistance, combined with proper care and regular cleaning, ensures long-lasting performance and enduring reliability over years of use. Equipping a professional kitchen team with the SO-70 and other knives from the PROFESSIONAL series is a conscious investment in reliability, refined workmanship and the highest standard of culinary execution.
