When are fillet knives necessary?


A fillet knife is basically a fish cutting knife. It is specially designed to clean fish before preparation. They’re fashioned to remove scales, bones and cut fish clean off the spine. They’re also flexible enough to move cut smoothly under the flesh.

Fillet knives are very different from other knives. They’re thinner than boning knives, allowing them to easily move through fish. They’re also thicker at the ends and pointer at the tips than carving knives. This allows more strength and easy picking of bones respectively.

With a fillet knife, you can cut and clean efficiently, whether in your kitchen or on the boat. It’s your best bet for trimming fat, deboning, descaling and cutting through flesh with ease. Surprisingly, these utensils are also very handy for preparing vegetables and segmenting citrus. And they’re also good for carving smaller food like carrots or radishes.

A fillet knife is a great addition to your kitchen. If you’re an angler, this handy tool makes preparing fish much easier. It’s also a great companion for those who regularly prepare fresh fish, professionally or as a hobby.

How did we pick the best?

Choosing the right fillet knife hasn’t always been easy. Back then, I would end up with one that’s either too heavy or too hard on my grip. Even when I began to follow reviews, it was still no good. Most times, I would buy a product based on how it looked. One time, I even bought a knife simply because it looked ‘expensive’.

It took me a long time to realize you don’t shop based on looks or hunches. I finally learned that you shop based on information gathered from research. Back then, I used to lose tons of money because of this. Well, not anymore. Now I know better.

Years of experience and lots of research have thought me what to precisely look for in a good fillet knife. And I am glad to say I’m not the only one who feels so. In this regard, I rubbed minds with other people who had the same drive and desire as I did. Together, we formed a team dedicated to fish out the best quality fillet knives on the market.

My team and I were spent a lot of time on web research, looking for the right information. We also sourced our data from numerous experts all over the web. We went through opinions from a large community of users, both locally and internationally. We also put into consideration basic factors such as blade thickness, sharpness and handle grip. With these, we were able to compare products and choose superior brands.

It is our duty as fellow enthusiasts to help you compile a detailed fish fillet knife review. This is why we ran extensive research on the specifications these products have to offer. We also ran loads of test on each product listed here to confirm its quality. The result was a comprehensive guide aimed at making sure you end up with a high-quality fillet knife.



Things to consider while buying best Fishing fillet knife

A good fillet knife is the difference between fish cutting like a pro and stabbing your fish in frustration. You want to go for something that gives you good value for your money. You need a blade that works like an extension of your very arm, cutting as precisely as you want. As such, you must consider the following factors before purchasing any fillet knife.

Design and Size

The combination of all its parts determines the overall design of the fillet knife, so it must be considered. They type of blade, thickness, handle material and specification of use will determine how the blade looks and feels.

It also determines what it works best for. Straight-edge blades are great for precision cuts. Serrated edges easily cut through tough scales and tapered tips Also, fillet knives come in small, medium and large sizes. What you choose depends on how large your catch is and the precise purpose of use.



All knives are basically made up of the blade and the handle. The blade does the main work- cutting- and as such must be closely analyzed. You look out for three things in a fillet knife blade before you pay for it; its material, its size, and its sharpness.

  • Blade material

What is the blade made of? How sturdy and durable is it? Is it easy to sharpen? Is it rust and corrosion resistant? Does it clean easily? All these are questions to be asked.

Generally, stainless steel is the most used for fillet knife blades. It gives positive answers to all these questions. High carbon steel especially answers the issue of sharpening best. Titanium steel is also used though, these are usually more expensive. Bear in mind though that the material must also be of high quality as not all are manufactured equally.


  • Blade size

You need to ask yourself if the size of the blade improves or hinders functionality for you. Blades come in varying lengths and your choice is based on how large the fish is.

Smaller fish like bluegills require more precision and that is best achieved with shorter blades (preferably around 5 inches). Blades around 7 inches are considered ‘all-purpose’ and are suitable for averagely sized catch such as bass. And for larger fish such as salmon, blades longer than 8-9 inches should be considered.


  • Sharpness

Fillet knives are basically made for precision. So they must come with razor-sharp edges that can cut precisely and finely through fish. The edges should also be able to hold well and not blunt too quickly. Plus, you need to make sure the blade sharpens quickly and easily to maintain the edge.


Handle Material

The other important part of the fillet knife is the handle. It gives you control of blade swing, cut and pierce. The type of material used must be on that is compatible with preparing and cutting fish. You’ll come in contact with lots of water, slime, and blood when cutting fish. So, you’ll need a handle that doesn’t slip easily due to all these.

The material used must also be comfortable for long use in cases where you need to work on lots of fish. Good fillet knives come with wooden, rubber or plastic handles. When choosing, go for the type that agrees with your handling.


Comfort and Grip

Using a fillet knife requires you feel right when handling it. That way, you can cut and fillet with much ease. The best fillet knife for you is that which feels natural upon handling. Make sure the handle material is comfortable to your grip. Make sure it’s not material that makes your hands ache if you’re preparing lots of fish.

Also, ensure that the grip of the knife is solid and firm. Make sure it doesn’t slip easily or you’ll wind up cutting yourself more often than the fish. A good fillet knife will feel comfortable and sturdy to your grip, regardless of the condition.



The thickness of the fillet knife blade determines its strength. Thicker blades are usually stronger, allowing you to cut through larger fish. Thinner blades might have you struggling through that tuna. Before selecting one, ask yourself if the blade thickness will be strong enough to slice through your catch.



When filleting fish, you would have situations where you need to bend the blade for better precision. This refers to the blade’s flexibility. Thinner, shorter and smaller blades tend to be more flexible, allowing easier deboning and precision cuts.

Flexibility is often looked for when the fish to be filleted is small. Thicker blades are usually less flexible as this is not usually required when cutting larger fish. They make up for this by offering strength in size and length.


Safety and Hygiene

Filleting brings you in contact with a lot of blood and bacteria, especially with freshly-caught fish. This is why it is important to purchase a knife with safety features. Most fillet knives have dimpled handles to ensure firmer grips. Others come with finger guards between the handle and the blade junction.

Also, good sanitary features must be present on a fillet knife. There must be no gap between the blade and the handle at the meeting point. This avoids the accumulation of materials that can breed bacteria in areas that are hard to clean. A good fish fillet knife must be easy to clean.



Perhaps the most important factor to consider when buying fillet knives is what it’s really for. Different fish and different situations require different fillet knives. In order to get a great deal, you must ensure the knife will serve the purpose efficiently.

Smaller fish require shorter, thinner, more flexible fillet knives. Larger, stiffer, longer knives work best on tougher tasks synonymous with a bigger catch, especially saltwater fish. And freshwater species can be easily prepared with medium sized fillet knives.

Indoor tasks are best performed with an electric fillet knife. They also work best for bulk filleting or handling a wide variety of fish. Manual knives are your best bet for outdoor use as they don’t need a power source.


Electric vs Non-electric

Originally, fillet knives are manually operated, just like regular knives. This gives you complete control over cut depth, precision, and flexibility. However, some power-using models have been introduced. These electric fillet knives are most useful when filleting large quantity of fish, making the process faster. Most of them come with changeable blades, each fashioned for a particular purpose. This way, you’re allowed to work on a wide variety of fish.

Many though, prefer to be in full control of the fillet knife and prefer the non-electric models. In the end, it boils down to what you prefer and if time is an important factor.
