Things to consider when buying a fillet knife

Are you thinking of buying a new filleting knife? Well, before you buy a fillet knife, you need to compare several fillet knives by looking at their features. Therefore, before you invest your hard earned money to buy a fillet knife, it is important to find a quality knife with a super sharp blade.

Here are some of the things to consider when shopping for a fillet knife to ensure you make an informed purchasing decision.

Sharpness and blade material

You will realize that most fillet knives are made from high quality stainless steel. This premium material will ensure the knife has a super shape blade. However, filleting knives are made by different materials and it is imperative for you to find a superior knife with better flexibility and maximum performance.

Most people nowadays prefer fillet knives as they are constructed from quality stainless steel. And the good thing is that stainless steel is a tough material, but might be challenging to sharpen. But after sharpening, the blade will retain its sharp edge longer!

Carbon steel is also another material commonly used in the manufacture of fillet knives. Carbon stainless steel knives are corrosion and rust resistant. More importantly, they don’t require no expertise to sharpen. Additionally, they are durable and lightweight for easy storage.

Comfort and handle material

You should identify a fillet knife with the best handle for balance and comfort. Some of the best handles are made of wood, rubber, or plastic. As far as choosing a good handle is concerned, you should find the best handle that suits your preference and needs. Often, many people prefer wooden handles as they are lightweight with a visual appeal.

Unfortunately, wooden handles can get slippery when it's wet. And they can easily get damaged when exposed to water for a long period of time. But plastic handles are safe to use in water and are comfortable as well. A good example of a fillet knife with the best handle for grip and comfort is the Rapala fillet knife.


Another factor you should consider when buying a fillet knife is flexibility. This is an important aspect because knives with flexible blades aren’t vulnerable to breaking. Flexibility will also come in handy when filleting a large size fish, be it catfish or salmon. Fortunately, many fillet knives offer added flexibility when filleting fish.

Long and thinner blades offer better flexibility than shorter blades. However, a short blade is ideal if you want to prepare small fish at home. Therefore, you should buy a knife with a flexible blade so that you can perform your filleting tasks with ease. The knife should offer you an easy filleting experience without any pain on your hands.

Weight and size

Often, fillet knives come in different sizes to suit different tasks in the kitchen. The fillet knife you decide to buy will depend on what type of fish you want to cut, as well as the size of the fish. For example, a short blade might not be suitable for filleting a large fish. You can opt for a 6-inch blade, which is perfect to fillet all fish sizes.

And choosing a light fillet knife will improve your filleting speed significantly. If you choose a heavy knife for your filleting tasks, you may not complete the task effortlessly. That said, you should shop for a lightweight and flexible blade for easy filleting.

Safety Features

Remember that fillet knives are dangerous if not properly handled. This is because they bend easily and are super sharp than your regular knives. Safety is therefore of the utmost importance while filleting poultry or fish. For that reason, you need to look for a special knife that comes with a finger guard or safety bolster. That way, you never have to worry about injuries to your fingers while filleting.

It is important to identify the right fillet knife that has a safety bolster so that you always stay protected. Fillet knives that come with a safety guard are the best option for filleting. Fishermen and professional chefs recommend safety guard fillet knives, too!

Read customer reviews

You should find a knife from a trustworthy company and this is only possible by reading customer reviews online. Buying a fillet knife haphazardly from unknown brands is not the best way to go as you might experience issues with the knife later on. Do they offer a guarantee? And do they have reliable customer service?

Quality of handle

When you buy a fillet knife with a poor handle that is slippery, just opt for an alternative option. You can choose fillet knives with plastic or rubber handles ( and avoid those with wooden handles). Remember that buying a fillet knife that has a sturdy, slip resistant handle is an excellent option long-term.

What length fillet knife should you buy?

As you compare fish fillet knives, you will realize they have different blade lengths. And if you are a newbie cook, it can be confusing to make an informed choice if you don’t have experience in filleting. What is the right blade length? Well, knives with a short blade are excellent for filleting small fish as they offer higher flexibility. On the other hand, longer blades are perfect for filleting large fish.

As a suggestion, you should look for a fillet knife that is between 6 and 8 inches as this is the best ‘’all size fits all’’ option. That means you can use the knife for different fish sizes without using too much effort.

What is the blade type?

When shopping for a fillet knife, it is also important to look at the blade as this can make a huge difference. That means you should look for a fillet knife that is easy to sharpen and can retain its edge longer.

Another thing to consider is whether the blade is rust or corrosion resistant. Is it safe to place it in a dishwasher, or should you hand wash it? While most people prefer to use a hand washer, it is always advisable to wash the knife by hand to prolong its lifespan.

Filleting vs boning knife

Filleting and boning knives might look similar but they are actually different. In fact, when you look at them closely, they have entirely different features. For example, boning knives normally have a sharp tip and narrow blade. Moreover, they have a pronounced straight spine that is ideal for separating meat from bones.

On the other hand, fillet knives are narrower with flexible blades. And rather than having a sharp pointed tip, they are generally arched. This makes them ideal for separating meat from bones when filleting fish.


For effortless filleting, it is important to have a quality fillet knife. That means you need to find a lightweight and flexible fillet knife. It should be sharp and easy to use, and should have a safety feature as well to keep you protected.
