Check customer support availability to address any technical issues or maintenance questions promptly.

How to Use and Care for Your Cordless Electric Fillet Knife

Start by ensuring batteries are fully charged before your first use. Insert the blades securely and check that the safety lock is released before engaging the motor.

Hold the knife firmly with your non-dominant hand to stabilize the fish. Guide the blade along the spine using smooth, steady strokes to remove the fillet efficiently.

After use, clean the blade thoroughly with soap and water to prevent corrosion. Store the knife in its protective case with blades detached to maintain sharpness and safety.
