Best Fillet Knife

Some of you don’t know that a fillet knife is a special type of kitchen knife. It isn’t the same as a boning knife, despite the fact they look the same. Here we can see a major difference. A boning knife is made for removing bones only from the meat.

A fillet knife is designed for removing bones and skin from the meat. As such, it is usually thinner, more flexible and easier to use than any other type of a kitchen knife. Choosing the best fillet knife is far from an easy task.

A fillet knife is a mandatory addition to any kitchen. It is something that can make a difference between spending hours in a kitchen and ending up with a poor meal or completing the task in seconds and get the best meal possible.

German G4116 steel

The special type of steel used here offers the best combination of flexibility and strength. The blade is super-strong and can be used for all kinds of operations you can possibly think of. The blade also looks nice and is razor-sharp.

We were able to cut through anything easily and within seconds. The steel is truly remarkable and probably one of the biggest benefits this model has to offer. There is no need to add that the knife is immune to corrosion and stains.

All sizes available

The knife is available in all sizes, you can think of. We tested 5- and 9-inches versions, but you can have the same model in 7 or 8 inches in length. In a nutshell, all of them are made in the same way and they look identical, but the difference is obvious.

Polymer handle

The handle is special. First and most importantly, the handle is comfortable to hold. It is very easy to clean, and it offers an immense level of grip. All of that we like, and we pay close attention to each factor. However, it is available only in orange color, which may be an issue for some of you.

Rapala Fish n Fillet Superflex Knife

Rapala Fish n Fillet Superflex Knife

The tested model is so different and unique that it looks more like a hunting knife than a fillet knife. Don’t the design confuse you, this is an actual fillet knife and now you will see all the main benefits it has to offer. There are a lot of them.

PTFE coating

The blade is coated by PTFE compound which isn’t toxic and has been approved by various organizations. The coating has an important role to do. It will make the blade smooth and slippery so the fillets will fell off it as you cut.

We noticed that on our tests and we had to say, we are impressed. You can clearly see the difference and you can use less force to cut and remove skin and bones from the meat. The coating is durable and will stay there if needed.

Leather sheath

One of the reasons why this model looks like a hunting knife is the sheath. It comes in the package and it allows you to carry or protect yourself and the blade at any given moment. The sheath itself is strong, durable and looks nice.

Polished brass ferrule

Ferrule is a part of the knife between the blade and a handle. It is a nice addition to this model, specifically due to the design it offers. It is made from polished brass and it can make this knife more expensive than it is.


  • Polished brass ferrule
  • 3 different versions
  • Leather sheath
  • PTFE coating


  • Finger guard
  • Too flexible for some users

How To Choose The Best Fillet Knife

In order to get a fillet knife that has all you need and can be used for removing skin and bones from all kinds of meat, you need to know what to look for. These knives come in all sizes and shapes so unless you are a professional chef, you will have a hard time finding one that is great.

We tested thousands of knives over last year and we know what to look for. Now is the time to share all of that with all of you and to help you make a difference between a decent and the best fillet knife.


Material isn’t the most important part or factor of a fillet knife. It is the most important factor for any knife. Here the situation is a bit different. Your blade must be strong, but flexible as well. Chances are low that you will find a model with a high carbon blade.

The best option is stainless steel. This material is tough, immune to corrosion and stains. But it is strong as well while providing the right amount of flexibility. We highly recommend you take a closer look at models made from stainless steel only.

Length of the blade

A fillet knife can come in various lengths. Yes, the average knife will be between 6 and 7 inches long. These knives are generally the most usable and the best for all kinds of applications. They are easy to use as well, and they won’t occupy a lot of space in a kitchen.

There are smaller fillet knives also. They are 5 inches. Some are much larger, and they are 9 inches in length. Unless you need an extra-long knife, 7 inches are the best choice you can make.

Manual or electric?

A fillet knife can be electric or manual. If you have a need to use a fillet knife many hours every single day, go for an electric model. It is a worthy investment. If you use it occasionally, as most of us, you will get all the perks from a manual knife.

The major difference is in the price. Fillet knives are affordable, but electric fillet knives aren’t. They are expensive and they are used by professional chefs or specialized kitchens.


The material of the handle is the first thing to look for. Wooden handles may look great, but they can’t last long, and they are very slippery when wet. This has a negative effect on safety and should be avoided.

Some handles are made from plastics, while others from polymers. The second option is the best one you will ever need. They are strong yet they offer an immense level of grip and you can use them if needed.

The second sub-factor here is the grip. A handle must provide an excellent level of grip all the time and especially when wet or oily. Models that are ergonomic are usually excellent in this field.

Finally, a handle must be comfortable to use. Choose accordingly to your hand size. A bigger hand requires a bigger handle, obviously. Once again, we can see that handles made from polymers are the best choice.


A fillet knife must be flexible yet strong. Here you can see a major difference. Thicker blades are less flexible, and they are used for removing bones from red meat. Thinner blades are more flexible, and they can be used for removing bones from poultry, fish and red meat.

This factor is determined by the type of meat you prepare in your kitchen. Those who use mostly poultry and fish will need more flexible knives. Those who prepare red meat or beef will need thicker blades.

Finger guard

Most models have a finger guard. After all, your hands will be wet and oily most of the times you use a fillet knife. That’s why a finger guard is a mandatory element to any fillet knife. We highly recommend models with this addition and we believe it is one of the most important, small advantages a fillet knife can provide.

There are still units on the market that don’t have finger guard. They are less safe to use, and they are mostly the low-end models. We don’t recommend knives of this kind.


Some fillet knives are more than just affordable. Others are more than just expensive. Regardless of which unit you want to get, make sure it is paired with an excellent warranty. By doing this, you can be positive that that knife will last for decades.


What is the best fillet knife for salmon?

To get the best results, we recommend any fillet knife which is thin and offers superb flexibility. The brand and the type of fillet knife are not crucial factors. The best fillet knife for this purpose will be around 6 inches long, although a longer unit can do the job well also.

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

A boning knife is made for removing bones only. It is usually thicker and less flexible than a fillet knife. A fillet knife is made to be used for removing skin and bones from all kinds of meat. These two knife types may look similar, but they are far from that.

What is the best boning knife?

The best boning knife depends on what meat you want to prepare. Red meat will require a larger knife with a bigger handle. Fish and poultry will require a smaller knife with a more flexible blade. A handle must be ergonomic and easy to use to get the best results.

Where is Bubba blade made?

These knives are made in China, from high-quality stainless steel. They are very popular now and they are known for superb quality at an affordable price. Some of the best fillet knives are made precisely by this brand.
