Fish knife ETERNUM Adagio E-2090-17-12 — flexible blade for filleting

The ETERNUM Adagio E-2090-17-12 fish knife is a kitchen tool designed specifically for filleting and portioning fish. It has a narrow, flexible blade that follows the contours of the fish, allowing precise cuts along the backbone and efficient removal of skin. The knife’s balance and handle shape support a controlled grip for delicate work with whole fish or fillets, suitable for both home cooks and professional kitchens.

Advantages

The flexible blade design enables accurate cutting close to bones and skin without damaging the flesh. A slim profile and fine tip improve maneuverability when separating fillets, while the ergonomically shaped handle provides better control during repetitive tasks. Constructed for kitchen use, the knife simplifies portioning and finishing, reducing waste and improving presentation.

Suitable for

• Filleting whole fish and removing skin
• Portioning fillets for cooking or storage
• Precision trimming near bones and fins
• Home cooking and professional fish preparation

Key specifications

• Blade type: narrow, flexible fillet blade
• Primary purpose: filleting and portioning fish
• Handle: ergonomic design for controlled grip
• Typical use environment: kitchen (home or professional)

How to use

Place the fish on a stable cutting surface and hold it firmly by the head or tail. Start the cut behind the gills and use the flexible blade to glide along the backbone with smooth, even strokes, keeping the blade angled to follow the fish’s contours. Use the tip for detailed trimming around fins and bones and the length of the blade to separate fillets. For skinning, hold the fillet skin-side down, secure the tail end, and use a shallow angle to slide the blade between skin and flesh while pulling the skin taut.

Usage recommendations

Maintain a sharp edge for precise filleting and wash and dry the knife after each use to prevent corrosion. Store the knife in a dedicated slot or protective sheath to protect the flexible blade and avoid contact with other utensils.
