How to use

Place the fish on a stable cutting board and hold it firmly by the head or tail. Use the flexible blade to make an initial cut behind the gills, then run the knife along the backbone with smooth, controlled strokes to separate the fillet. Angle the blade slightly toward the bones to remove as little flesh as possible. When skinning, start at the tail end, hold the skin taut, and slide the blade between skin and flesh with steady pressure. Rinse and dry the knife after use and store it in a safe place.

Usage recommendations

Regularly maintain a sharp edge appropriate for filleting to ensure clean cuts and safer handling. Avoid twisting or prying motions that can damage the blade. For longevity, hand wash and dry the knife immediately after use and store it away from other utensils to prevent nicks.
