Boning Knives and Fillet,Knives
What's the Difference?
In the kitchen, two specialty knives are incredibly useful yet often confused: the boning knife and the fillet knife (sometimes called a "fish knife"). You might ask: What sets them apart—and can one substitute for the other?
Boning Knife:
Fillet Knife:
TUO Fillet Knife shares a similar heft and profile to a boning knife but features a distinctly thinner, more flexible blade, engineered for exceptional precision. This flexibility makes it the perfect tool for filleting fish, preparing smaller delicate cuts of meat, and skillfully removing skin and scales – ideal for tasks like preparing halibut. The blade's unique pliability allows it to effortlessly conform to bones and contours, enabling clean carving and slicing of delicate items without tearing or damage. This translates to effortless control and precision during intricate knifework.
What They're Used For:

Start with beautiful chicken thighs destined for crispy, golden skin in your cast-iron skillet.
Step 1: Grab your trusty boning knife.
Step 2: Place the thigh skin-side down on your board, securing it firmly with your non-knife hand.
Step 3: Holding the blade flush against the bone, carefully slice diagonally along both sides to separate the meat. Always cut away from your fingers!
Step 4: Once the bone is exposed, use the knife tip to slide underneath and dislodge it completely.
Step 5: Remove the bone.
You've got this! Perfect technique comes with practice.

Ready to prepare delicious monkfish tails?
1. Position the Fish: Place the monkfish tail skin-side down on a stable cutting board. Secure it firmly with your non-knife hand, keeping fingers clear.
2. Start the Cut: Using your sharp WÜSTHOF fillet knife, carefully slide the blade between the thick skin and the firm white flesh. Cut approximately two inches inward to separate the skin from the meat.
3. Secure & Tension the Skin: Flip the tail. Firmly grasp the loosened skin with your non-knife hand and pull it taut away from the fish.
4. Remove the Skin: With controlled, gentle strokes, guide the flexible blade of your fillet knife along the skin-flesh junction, slicing smoothly to remove the remaining skin.
5. Cook & Enjoy: Your perfectly skinned monkfish is ready! Pan-sear it in butter with fresh lemon and rosemary for a simple, flavorful dish.
