Designed for precision and ease, the Marttiini Superflex 15 takes filleting to the next level with an ultra-flexible blade and thoughtfully crafted handle. Perfect for processing fish around 1 kg, this knife offers exceptional control for clean, smooth cuts every time.
The 6" stainless steel blade is more flexible than traditional fillet knives, making it ideal for delicate, detailed work. The handle is made from heat-treated Finnish birch, finished with a protective wax for durability. A laser-etched surface texture enhances grip—even when wet—ensuring comfort and control during long cleaning sessions.
Complete with a brown leather sheath for safe storage, the Superflex 15 is a modern take on a classic tool—lightweight, reliable, and built for performance.
