Best Fillet Knives

Filleting fish is a lot easier when you have a high-quality knife that is specifically designed for the job. Ideally, the knife you use should not only be sharp but should also be comfortable to hold and easy to maneuver so that you can make your cuts with precision. Fillet knives can be used for skinning, descaling, and deboning fish, making them a must-have tool in the kitchen.

This is one task where quality matters. A dull, poorly-made knife will tear at the fish, making a mess and leading to a lot of waste. Low-quality knives can also be dangerous to use since they are more likely to slip. With a high-quality knife, on the other hand, you can cleanly cut through the fish with precision, allowing you to create picture-perfect fillets. Instead of being a chore, the right knife can transform the experience of prepping fish into an activity that you enjoy.

Whether you are a fisherman, an avid cook, or work in a meat shop, you should invest in a high-quality knife that you can turn to any time you need to fillet fish. Knives like these come in handy in many different situations, both in the kitchen and when fishing outdoors. In the section that follows, you can find reviews of some of the top-selling fillet knives.

One thing that makes this knife unique is that the blade is extremely easy to keep sharp. This has to do with the fact that it is made using grade 420 stainless steel. The higher carbon content of this type of steel makes it a lot easier to sharpen.

With an edge that is shaped like the letter “S”, a lightweight design, and superior flexibility, this knife is excellent for everyday use. Caring for the blade is easy since it is made out of ice-tempered steel.

The firebox handle not only has a textured surface but is also ergonomically designed, helping to ensure that it won’t slip when you are using it. Cutting fish can be a messy business. This knife simplifies the process, allowing you to work for long periods without experiencing wrist fatigue. Cleaning the knife is easy, as well, which is why the design of the handle has been approved by the National Sanitary Foundation.

  • Dalstrong Trust: Rocksolid 100% SATISFACTION OR MONEY BACK GUARANTEE,...

Like the Shogun Series 6″ knife by Dalstrong, the 6.5″ boning and fillet knife is extremely strong. The only difference is that the edge for cutting isn’t quite as sharp. Its semi-flexible blade is better suited to working with meat rather than fish. It is ideal for boning and filleting since its blade is sharp at the tip and is extremely narrow. That makes it possible to remove pieces of fish with a great deal of precision. The blade itself is engraved, which not only makes it more attractive but also makes it more effective at removing meat that is next to the bone. The stainless steel blade is cooled with nitrogen to make it more flexible. Its tapered design also helps reduce drag.

The handle is made out of beautiful Spanish pakkawood that has been polished by hand and specially laminated for extra protection. It is the ideal size to hold in your hand, allowing you to grip the knife tightly even when your hands are wet. The pin is made out of brass and copper and is designed with a beautiful mosaic pattern that makes the knife look more elegant. As a bonus, the knife is backed by Dalstrong’s lifetime warranty.

  • Getting the knife close to bones, under the skin, and around joints is easy thanks to the semi-flexible blade
  • The blade is extremely sharp, which allows it to perform well
  • The compact pakkawood handle is ideally sized for the average hand
  • The knife holds its edge exceptionally well and is extremely strong and durable
  • The sheath isn’t as well made as the knife

The 6.1″ model provides a lot of versatility in terms of how it can be used, while both knife sizes are quite flexible. They feature a slip-resistant grip that is designed for comfort, making it easy to control the knife while you work. The blade of the knife is made out of Sandvik stainless steel, which means that it does a great job of resisting corrosion.

There is a reason why this knife has the word ‘comfort’ in its name – its handle is extremely comfortable to hold.

10. Rapala NK03039-BRK Fish N Fillet

Rapala NK03039-BRK Fish N Fillet
  • Each Fish 'n Fillet features a full-tang Swedish stainless steel blade...
  • The genuine leather sheath and single-stage sharpener seal the deal
  • making it the "go-to" fillet knife in the fishing world.

The NK03039-BRK reminds me of one of the very first fishing knives that I had when I was a kid. The knife has a very traditional appearance with a birch wood handle that is quite nostalgic. I wouldn’t recommend this knife to be used by outdoorsmen who use their fillet knives every week since the steel of the blade isn’t the same quality as the other blades above. It is softer blade steel that would need to be sharpened more often since it won’t hold an edge for very long.

However, if you are searching for a high-quality fillet knife to use occasionally, then this knife can provide good value for your money. The Swedish stainless steel 7.5-inch blade is perfect for most sizes of fish. It has a nice looking reinforced birch varnished handle but won’t give the same grip that plastic does when it is wet. For such a low cost, it would make a really good backup fillet knife if you need one.

  • Comes with a sharpener and leather sheath
  • Low price
  • Lower quality of stainless steel blade
  • Softer steel so it will not hold its edge very long and will need to be sharpened more often

Why Do You Need the Best Fillet Knife for Fish?

Fillet Knives are designed specifically for filleting fish:

The blade is razor-sharp, thin, and very flexible, which makes it an easier task to cut across the backbone of the fish and to smoothly remove the skin. These blades usually also feature a very sharp tip which is useful for piercing into or through the body of the fish.

Fish come in various sizes and many different species. Fish filleting, in general, is a dangerous activity as it involves working in slippery and wet conditions along with mucus, which includes the intestines, blood, scales and the skin of the fish.

When using a knife of poor quality or a blade that is blunt, you increase the risks of really hurting yourself. It will usually take you a lot longer to try and fillet a fish and with the wrong knife and it becomes much harder to obtain nice pieces of fillets.

In most cases, you are probably wasting a large amount of good protein that you could have gotten out of the fish. In addition, it was probably already difficult to catch the fish in the first place.

For this reason, it becomes extremely necessary to invest in the right type of knife before you attempt to fillet fish.

  • To begin with, a fillet knife that is user-friendly will keep you safe along with a handle that not only feels comfortable in your hand but is also made from non-slip materials.
  • Secondly, the top-rated fillet knives are easier to use and control which will assist you in getting the most meat out of the fish as possible.
  • Thirdly, a fillet knife that is well-designed will assist you when it comes to improving your work efficiency, saving you effort and time when processing fish.

These are the most important advantages that the best types of fillet knives provide users with. Overall, this is an important tool when you go fishing as a fisherman.

Fillet Knife Types

The fillet knives come in all sorts of sizes, shapes, and designs, which is why it is important to find out about some of the features that these tools provide.

Standard Fillet Knife

These are the regular fillet knives. They come in different textures, colors, materials, and styles. The blade shapes and styles also vary, with some users preferring the knives that feature a curve that is slight which helps with taking the skin off of a fish. The blades are durable and flexible and you can usually fillet many fish before you will need to resharpen the blade.

Salmon Slicers

This type of fillet knife is typically 9 to 12 inches in length and are mainly used to fillet salmon and other similar types of fish. This knife has a blade that is designed to expertly slice salmon into pieces that are wafer-thin. The blade comes with a rounded tip which prevents damages to the fillet fibers. The blade may be longer on this knife, yet it still very flexible.

Electrical Fillet Knives

This knife is similar when compared to the standard fillet knife, excepting that it runs off electricity and a motor. These knives have more power than the standard knives and this version has increased in popularity over the years.

Buyer’s Guide: Tips on Choosing the Best Fish Fillet Knife

As a chef, cutter, or angler, using the correct filleting knife made for fish is vital. The knives on the market range from bad to average to excellent, so it becomes important to do your research to find a knife that matches up to what you need.

This is the knife that will make the task of filleting fish much easier. So you don’t want to make the mistake of spending your money of an inferior product that fails to produce the right results.

So you may be wondering what characteristics make a knife great for filleting? Before you choose a knife there are a few considerations to keep in mind to ensure you choose a knife that offers you great value for money:


This includes what the knife is made from. This will affect its overall durability, flexibility, and strength, along with how precise it fulfills its role.

Blade Material

The blade should always be made from high-quality materials which make the knife durable, sturdy, and flexible. It should also be an easy process to sharpen the knife so that it maintains a keen edge. The wrong blade is susceptible to corrosion and rust caused from exposure to water, and more particularly when you clean any of the saltwater fish. The blade should, therefore, be resistant to rust and corrosion as well.

Stainless steel is one of the more common materials used to make blades. It is durable, strong, corrosion and rust-resistant. Stainless steel is also easier to sharpen and it doesn’t stain. This type of metal handles scales, blood, and water well, and because it is resistant to rust, this makes these blades ideal for filleting saltwater fish. Other popular yet more expensive blades consist of high-carbon stainless steel. These blades are one of the easiest to sharpen.

However, it is important to note that not all blades are made equally. Some of the steel blades are an inferior quality which usually breaks or bend under pressure, they also dull easily and corrode. You need to ensure the steel construction is of high quality.

Handle Material

The handles of filleting knives are typically made from plastic, rubber, or wood. Each of these materials results in sturdy handles.

The wooden handles are usually attractive and are also comfortable to hold and use. However, wood is susceptible to absorbing odors, can become slippery, and exposure that is constant to water may cause the wood to rot. Plastic handles do not retain odors and they are hard-wearing. Rubber handles provide a superior grip.

You can choose which type of handle appeals to you the most, but it is still important to make sure it feels secure and comfortable in your hand while you are cutting while providing a secure grip to match up to your specific working environment.

Filleting Knife Styles: German Vs Japanese

The main styles of the filleting knives include the Japanese style and the German (Scandinavian) style. These knives share a number of similarities, yet there are few differences which will assist you in choosing which style suits you better.

German (Scandinavian) Style

  • These knives typically feature a double-beveled blade, which means you can sharpen either side of your blade
  • These are usually thicker blades which makes them heavier
  • There is also a larger angle to this blade which makes it more suitable for rocking-style chopping
  • The steel is usually slightly softer when compared to the Japanese style blades

Japanese Style

  • These knives typically feature a single-beveled blade, which means you can only sharpen the blade on one-side
  • The blade is thinner making the knife lighter
  • The blade has less of an angle which makes these knives suitable for chopping and producing clean slices
  • The steel used to make these blades are harder when compared to the German-style which makes these knives sharper

I personally prefer the German-style knives as they are more rugged and thicker which matches up to my environment, where I often fillet my fish outdoors in rough conditions. The Japanese blades are best suited for attention-to-detail and precise work. When I fillet many fish at once, I do not take a lot of time on every one, which means the Japanese blade does not suit my purpose. The German blades are also better for cutting and breaking through bones.


The overall design of a filleting knife will determine how it will perform and how easy and comfortable it will be to use.

To fillet fish precisely the blade requires flexibility in order to move smoothly between the bones and the flesh. Thin and long blades flex easily, which is why the filleting knives feature these blades.

The straight-edge blades are suitable for filleting because they are able to achieve clean slices and precise cuts. The serrated blades are more suited to penetrate through hard scales to reach the soft meat inside. The tapered tips serve the purpose of making it easier to reach those harder to reach spaces.

The handle on a knife will determine the type of grip that the knife provides and at the same time, the grip will also affect how well you can leverage and control the knife. The handle should ideally be sturdy and thick.

It should also be made in a way that it fits comfortably and securely inside your hand. The hold should be soft but firm along with a non-slip grip. The handle should also feature ergonomic designs to lower hand fatigue. The handles that contour to your hand is the preferable choice. The characteristics such as texture will improve friction while finger grooves happen to be a nice addition to these knives.

Another design element to look out for includes the balance of weight between the handle and the blade. The correct balance will make your knife easier to handle. The full-tang will make your knife robust and provide improved leverage and control.

The folding designs are ideal for safety, transport, and storage, yet it is important to make sure the knife is is sturdy and features a good design.

Hygiene and Safety

With a blade that is razor-sharp and is exposed to bacteria all the time, the filleting knives are dangerous tools. The design should promote sanitary and safe handling.

Fish are usually slimy and slippery, especially when they have just come out of the water. Protective finger guards and finger grooves situated where the handle meets the blade can assist with protecting your fingers from getting cut when your fingers slip.

Sanitary knives will include handles which are molded correctly into place as well as sealed in order to prevent any spaces or gaps between your blade and the handle. If there are any spaces present slime, blood, and flesh can build-up in these spaces which are harder to clean. This creates the perfect environment for bacteria to breed along with pungent odors. The handle edges that are thick also help to keep the bacteria from coming into contact with either your fingers or your hands.


One of the most important parts of a fillet knife is its handle. The design and quality of handle affects the overall comfort as well as safety of the knife when handling or cleaning fish. A handle that is comfortable will allow you to get a strong grip which will make your job safer, quicker and easier.

The handle needs to not only fit well in the hands but it should also be comfortable to hold and it should be thick and sturdy. However, it should also offer a soft yet firm grip to allow you to easily maneuver through the fish. The design should be ergonomic in order to minimize the hand fatigue in case you have to fillet a lot of fish.

The material can be rubber, plastic or wood but you need to make sure that the material you choose is a slip resistant. There is a lot of water, slime and blood involved when handling a fish and it may make the knife harder to hold. An excellent fillet knife should come with a handle that makes it easy to handle fish in a variety of conditions.


It is important for you to make sure that the knife is able to fulfil the required filleting needs. There are many different types of knives and these suit different needs. It also means that you can’t have just one knife for handling different types of fish. The choice of ideal knife will also depend on the type and size of the fish.

  • A stiffer, sharper, denser and longer blade is needed for a large fish. Such a large blade offers you the required strength and length to carry out the tougher filleting tasks. A crappie or bluegill is easier to handle with a flexible blade due to small size of the fish.
  • For saltwater fish, the best knife is one that has a long blade with enough stiffness to handle the bigger saltwater species. On the other hand, a medium-sized blade makes much more sense for handling fishes in lakes and rivers.
  • It is recommended to choose an electric fillet knife in case you want to handle large sized fish or a variety of fish indoors or for bulk filleting. An electric knife is fast and does not require you to make too much effort. Also, it’s relatively easy to change the blades in order to make different kinds of cuts.
  • If you want to buy a fillet knife for using outdoors, a manual knife is the right choice as you don’t need a power source to operate it. You also get greater control and that allows you to be much more precise when making cuts.

Size of Blade

Size of the blade determines the ease of handling a particular type of fish. These blades are available in a variety of sizes including 4 inches, 6 inches, 7.5 inches as well as 9 inches. You must be wondering about the ideal blade length for the perfect fillet knife. It depends on the size and type of fish you will be using it on. Blades of different lengths are suited for fish of different sizes and types.

A good rule of thumb is to go for a blade length that is a bit longer than the depth of the fish you are going to fillet at its widest point. This length will ensure that you need only one pass to fillet which will result in a solid and clean cut.

  • The shorter blades ranging from 4-5 inches are best suited for smaller fish such as walleye, panfish, crappie or bluegills as well as for other delicate tasks and tricky boning. Shorter length blades give you the control and flexibility required to maneuver through the flesh and bone to make precise cuts.
  • For medium-sized fish such as bass or trout, the idea length is medium size of 6 to 7.5 inches. It’s a versatile size and is regarded as a good all-purpose option.
  • Bigger sized blade with length of 8 to 9 inches are best for handling bigger fish such as salmon, tuna as well as steelhead. Such large fish require longer and stiff blades for difficult filleting tasks. These are also great for saltwater offshore fishing, fish shops as well as large-scale jobs in restaurants.

Thickness of the blade is also an important factor when it comes to handling different types of tasks. A thinner blade is going to be more flexible which is great for handling smaller fish as well as other fine works. Thicker blades are less flexible but it also makes them sturdier and stronger. For instance, blade strength is needed to handle larger fish and that’s why a thicker blade is the right choice for handling bigger fish.


It’s extremely important for a filleting knife and this is the reason, all the fish fillet knives have a long and thin blade that allows it to bend easily in order to allow the chef to maneuver between delicate fish bones and flesh. However, there are certain knives that offer much more flexibility.

As far as the need for flexibility or stiffness is concerned, it depends on the size and type of fish that is being handled. The stiffness or flexibility of the blade depends on the size.

For more flexible option, you will need to choose thinner, shorter and smaller blade. If the flex is too little on a shorter blade, you will find it difficult to use it properly which will affect the final result. When you are filleting small fish, it is recommended to choose shorter and thinner blades that offer more flex. Such blades are also great for delicate tasks as well as for removing the bones where flexibility is needed in order to cut tight angles and to make those precise cuts.

Blades that are longer, thicker and larger offer less flexibility but have more strength and stiffness. These shouldn’t be too flexible as too much flexibility makes them flimsy. Stiff or semi-stiff blades are the best option for filleting larger fish and tougher cutting jobs.


The most important part of a fish for filleting is the blade. The blade will determine the type of cut that would be made using the knife as well as the cleanliness and accuracy of the cut. The best knives are sharp and hold the edge well and remain razor-sharp.

The blade of knife needs to be so sharp that it cuts right through the fish without any jagging or tearing. Making fine cuts is extremely easy with such sharp blades and does not require you to put too much pressure. It is also recommended to regularly hone the fillet knife in order to keep it sharp. Even the sharpest knife blades are going to lose their edge without regular upkeep. It is recommended to invest in an electric fillet knife for heavy duty work.

Dealing with a Mess of Fish

When you have to deal with a lot of fish, you must be wondering how long it’s going to take clean all the fish. In such situations, it’s better to invest in an electric fillet knife. It is specifically designed to speed up the filleting process and it also helps in minimizing the efforts for fishers. It is great for avid fisherman who need to deal with a huge amount of fish in many different sizes.

  • An electric knife comes equipped with a powerful electric motor that offers the required torque and power to cut through fish fast and effectively.
  • It makes use of reciprocating blades of various lengths and it’s easy to switch the size of these blades in order to match them with the size of the fish.

Sheath of Knife

It is also an important factor when it comes to choosing the right fillet knife. Due to extreme sharpness of a fillet knife, it’s extremely easy to hurt ourselves as well as others around us. Also, it’s easy to blunt.

This is the reason, it is recommended to choose a fillet knife that comes with a sheath making it convenient for you to carry and store it and a sheath also makes it safe for users.

How to Sharpen a Fillet Knife?

When it comes to filleting mats and fish your fillet knife must have a sharp edge, and there are few ways to sharpen a fillet blade just right. The tool you use to sharpen your knife should be chosen for convenience and proper function.

Manual Methods: Sharpening Stones

If you are in the great outdoors, a sharpening stone is the most convenient solution. Whetstones and diamond stones are available and very practical options.

The best advantage of a sharpening stone for creating the perfect edge is the level of control you will have over the blade and stone.

The downside with the manual method is that it does take some time and experience to master and doing it all wrong can potentially ruin your blade. This is why it is a good idea to practice this skill on cheaper knives before attempting to sharpen a better quality expensive knife.

The most important thing to achieve will be getting the right angle and developing consistency of motion. Imagine you are slicing a block of butter this angle will be perfect. The handle should be held a little higher than the stone and the motion needs to be smooth even and fluid. Glide the blade lightly and smoothly back and forth on both sides until the blade has the edge it needs for proper use.

The Electric Method

For speed and convenience the electric blade sharpener offers a technological shortcut to a decent edge. There are generally two settings on the average electric blade sharpener. The first is a grinder setting that places an edge of your knife through cutting away steel. The other setting is to hone the blade which ads the protective finish to the ground edge.
