Big Fillet knife

This handmade Big Fillet knife is a reliable tool crafted for precision and finesse. With its 19 cm blade, this knife is ideally suited for processing fish in the 2–3 kg range, a length that offers the perfect balance between control and flexibility during filleting. Whether you're standing by the water with the day's catch or preparing dinner at a remote campsite, it delivers clean, accurate cuts every time.

The blade is forged from Roselli’s premium carbon steel, renowned for its razor-sharp edge, excellent durability, and long-lasting sharpness. It handles both delicate detail work and tougher cuts without sacrificing control.

The handle is made from beautifully stained curly birch, treated with linseed oil to ensure a natural and secure grip, even in wet or slippery conditions. Each knife comes with a handcrafted sheath made from dark, vegetable-tanned Finnish leather.

Whether you're a sport angler, wilderness cook, or outdoor enthusiast, this fillet knife is a testament to purposeful design and enduring quality, built to last a lifetime.
