What is a Fillet Knife? | Things You Need Know Before Buy

Fillet knives are important tools for people who like seafood. But not everyone knows what is a fillet knife, and I think you might be one of those who are unfamiliar with it. Do you know one thing, a good fish fillet knife can make it much easier to cut fish neatly and waste less.

Yes! You read it right.

This is why you need the best fillet knife. But before anything else, let’s first understand what it is.

What is a Fillet Knife?

A filleting knife is mainly for slicing poultry into thin pieces, especially to remove the skin. It’s great for cutting chicken or fish, which are fragile meats. The way the knife is designed is critical to make sure you get a clean cut.

1. Design of Fillet Knife

I enjoy how the fillet knife is made. Because it’s thinner and different from normal knives. Plus, you can make thin slices with this slim blade that tapers towards the tip. Also, it’s comfortable because the blade is shorter than the handle, now you can hold and cut precisely.

2. Features of the Fillet Knife

The standout thing about a fillet knife is that it’s slim and sharp. The tip is pointy to pierce the meat easily. It’s made to cut with precision and handle delicate meats without messing them up. 

Another special thing is that the blade is flexible, making it easy to move along the skin, flesh, or cartilage.

3. Blade Length of Fillet Knife

Now, talk about its blade because it is essential for any knife. Fillet knife comes in different blade sizes. Such as 4 to 6 inches, 7 to 8 inches, and 9 to 11 inches. You can use it for different kinds of fish.

Smaller fish, like Trout or Mackerel, need a shorter blade, while longer blades are better for bigger fish like Tuna, Catfish, or Halibut.

What is a Fillet Knife Used For? | Practicality

A fillet knife isn’t just for cutting fish; it can also help you with other tasks in the kitchen:

  • Cutting Chicken: Use it to slice chicken, especially the breast parts. It’s good for getting thin slices and removing extra fat. Also, handy for opening up chicken pieces.
  • Decorating Veggies: A fillet knife is great for making fancy designs on veggies like carrots or tomatoes, making your dishes look better. I’ve personally tried this, and my friends at home love it.
  • Cleaning Fish: Besides cutting, it helps clean fish by taking out the insides. Remember to clean the knife afterward to keep things hygienic.
  • Slicing Meat: Now, you don’t need any special slicer. Yes! The fillet knife is handy for making thin slices of meat.
  • Prepping Fruits and Veggies: Use the fillet knife for peeling fruits like citrus or avocado. It helps take off the skin without wasting any of the good stuff. Great for getting fruits and veggies ready for salads.

What Makes a Good Fish Fillet Knife?

Professional knives can be expensive, but they give you good value for money because they work well and last a long time. To know if a knife is good, look at:

1. Handle & Blade Material

The blade should be high-carbon stainless steel for sea fish. Choose a handle material you like – wood is sturdy but requires more cleaning, while plastic or rubber handles are easier.

2. Sheath

A cover (sheath) is good for keeping the blade safe when stored with other kitchen tools.

3. Blade Length

Pick the right blade size – As I mentioned before, the size of the blade depends on the size of the fish. Short blades are good for small fish, and long blades are better for bigger ones.

4. Flexibility

I’d recommend a flexible blade that helps avoid bones and gives precise cuts.

Things to Consider in a Fillet Knife

Decide based on your needs – fancy or basic, depending on your kitchen and how often you use it.

  • Knife Origin

Countries, like Japan and Germany, are known for making wonderful knives. Japan is great at making knives for seafood, and Germany is famous for creating high-quality kitchen knives.

  • Ergonomics and Safety

Comfort and safety should be your top priority. That’s why you need to test how the knife feels in your hand. Now, check if it is comfy and easy to use or not.

  • Price

You don’t need to spend too much, because you can get a basic one for $20-$30. But if you have the power to spend more, then I’d recommend going with a fancier option.


What is the difference between a fillet knife and a boning knife?

A boning knife is heavier and stronger and used for separating meat from bones. But a fillet knife is lighter and more flexible, perfect for cutting fish just right.

Do you need a fillet knife?

Yes, especially if you like cooking fish! Whether you’re a chef or love making fish at home, a fillet knife is super important. It helps you cut fish easily, so you don’t waste any. It’s a must-have for anyone who enjoys seafood.
