Let’s look at a filleting knife’s parts to see how it works:

Blade: A filleting knife’s blade is narrow and 6–11 inches long. This lengthy form makes filleting easy and precise. Stainless or high-carbon steel blades are durable and sharp.

Handle: Filleting knives include ergonomic handles for comfort and grip. Wood, plastic, or composite materials give it solidity and reduce slippage.

Flexibility: Filleting knives must be flexible. The blade’s flexibility helps it manoeuvre around bones and curves to extract flesh from the bone with minimal waste.

Techniques for Using a Filleting Knife


Proper technique and ability are needed to cut cleanly with a filleting knife. Filleting knife techniques:

Grip: Hold the filleting knife firmly but relaxed. For increased control and stability, place your index finger along the knife spine.

Safety: Secure your cutting surface to avoid mishaps. Avoid injury by cutting away from yourself.

Preparation: Clean and descale the fish. For simpler handling, refrigerate or freeze the fish.

Initial Incision: Start with a slight incision behind the gill plate or pectoral fin. Insert the knife tip into the incision and glide it along the backbone, angling it towards the head.

Follow the Contour: Keep the blade against the bones and follow the fish’s outlines when filleting. Separate flesh from bones with smooth, steady strokes.

Keep a Steady Angle: Keep the blade at the fish’s bones. Most fish prefer 20–30 degrees.

Use the Knife’s Flexibility: Filleting knives can readily manoeuvre around bones and joints. Control the fish using the knife’s flexibility.

Remove Rib Bones: Rib bones may appear as you continue. Carefully cut along the rib bones to remove them without losing meat.

Tail End: Carefully cut through the flesh and follow the tail’s form to separate it from the fillet.

Remove Skin: Hold the fillet firmly and slide the knife between the flesh and skin at a shallow angle to remove the skin. To separate the skin from the fillet, gently press and pull.

Remove Pin Bones: Remove pin bones after filleting. Remove them with tweezers or fish bone pliers for a boneless fillet.

Tips for Using a Filleting Knife


Consider these filleting knife maintenance tips:

Keep it sharp: Clean slices require a sharp filleting knife. Keep the blade sharp with an honing steel or sharpening stone.

Clean and dry: Wash and dry the filleting knife after each usage. This avoids rust and preserves the blade.

Use a cutting board: Use a solid wood, plastic, or bamboo cutting board to protect the blade and avoid mishaps. Glass and ceramic can blunt the blade.

Secure it: Protect your filleting knife with a sheath or blade guard. The blade stays sharp and prevents cuts.

Practice proper knife skills: Learn and practise proper knife skills for safety and optimum outcomes. This includes proper knife handling, control, and cutting actions.
