What is a Fish Fillet Knife?

It may seem a childish question as the answer is very much in the name. Everyone that loves to eat fish, knows that a fillet knife is a kitchen knife that is specifically used for filleting. It is a very flexible member of the boning knives family that is used to prepare very delicate meat especially fish so you don’t swallow bones or scales.

The shape and blades are specifically designed in a way to provide a strong grip and move efficiently along the backbone and under the meat.

What is the Difference Between a Fillet Knife and a Boning Knife?

Generally, filet knives are a member of the boning knife family but still, there are some major differences between fillet knives and boning knives. Fillet knives are usually thinner and have more flexible blades that have extreme strength and length. They are specifically designed to separate the skin or fish from bones. You can use this knife to cut any small or big size fish such as salmon, tuna, and catfish.

On the other hand, Boning knives don’t have blades as flexible as fillet knives. Their blades are specifically designed for speared bones. Boning knives usually come with semi-flexible and short blades, that’s why they are smaller than fillet knives. Benign knives are specifically used to deal with different kinds of meat such as beef and poultry.

What to Look for When Choosing a Fillet Knife?

If you really want to put your hands on the best fillet knife you need to look for some features before buying one for you. Here we have crafted some of the most important features that need your attention when buying a fillet knife.

Blade Material & Sharpness

First thing first! Whether you are buying a fillet knife or a regular kitchen knife, a blade with high-quality material and optimal sharpness should be your first preference.  Most filet knives are made of stainless steel, carbon steel, or high-carbon steel, as they offer high-end razor sharpness. 

Blades with stainless steel material are usually the sharpest and highly durable. You don’t need to sharpen the blades, because the edge remains sharp for a long time. These types of knives are usually strong, sturdy, and quite affordable. So, if you are a chef or cut fish regularly a stainless steel blade is an ideal choice for you. 

Meanwhile, carbon steel blades are quite expensive but they are easy to sharpen. These knives are usually lightweight and easy to handle. They are highly resistant to rust and corrosion.

Blade Thickness & Flexibility

Remember, if you are going to buy a knife pay close attention to its flexibility as this feature allows the blade to bend and make a clean, high precision cut. The flexibility of any blade lies in its thickness and size. Larger and thinner blades are considered more flexible and reliable as compared to shorter ones. A perfect fillet knife should have a thickness of approximately 1.5- 3.5 mm.

Size & Weight

You should also pay close attention to the size and weight of the knife. Fillet knives come in various sizes from 4 inches to 9 inches. So, you need to select the knife according to the size of the fish you want to fillet. If you are working with a small fish a large knife will not do help you. You should go for a knife with small blades.

Apart from the size, the weight of the knife also matters a lot. If you choose a large and heavyweight fillet knife, you may not handle fish well on the table. So, wisely choose the knife with high flexibility, lightweight, and wicked sharpness for fast and effortless filleting.

Price & Other Safety Features

Whether you’re buying home accessories or any other thing you always have to pay close attention to the price. Carefully determine your budget and choose the knife that comes with the most features at an affordable price. Most fillet knives come in a range of $10 to $50. 

Meanwhile, also check for the safety features in the knife. Since fillet knives are quite sharp and can cut any kind of fish bones and meat, you should pay attention to your safety while buying. Always buy a knife with a safety bolster or finger guard to protect your finger from sharp blades during fileting. 

After reading this brief guide now you have a good idea about fillet knives and what features you need to consider before buying a knife. Now let’s take a look at some of the top fillet knives that our experts have chosen for you.
