13 Best Fish Fillet Knife Recommendations to Fillet easily


Preparing your fish isn’t as easy as grabbing a knife out of your drawer. Your fish fillet knife is one of the most crucial tools you will have in your fish preparation arsenal. Whether you are preparing salmon, snapper, or bass, you will need to choose a fillet knife specifically designed to accommodate that particular job. There are probably more options that you are ready to investigate.

The common and incorrect assumption is that any knife will cut fish, but nothing could be further from the truth. A fillet knife has a special thin, curved blade, explicitly made for working through the fish without destroying the fish’s meat. 

Several choices of a blade consist of varying sharpness, length, and flexibility, all of which are important to the type of fish you prepare. You also want to ensure that the knife’s handle is comfortable and allows you to control the knife safely. 

There are several fillet knives on the market, but we’ve made a list of the best ones so that you can choose the best fish fillet knife for you and your specific needs.

Guide to Determining the Best Fillet Knife for You

When you are an avid fisherman or cook, you know that a fillet knife is not just another knife. There are a great many choices, but not all of them are created equal. 

When choosing the best fish fillet knife, many options need to be weighed out, and various pros and cons to consider. Selecting the best fillet knife for you is not merely based on what is most available, but what will help you do the job best, and which knife will perform the best and last the longest. 

Choosing wisely will help prepare your fish with precision and help keep you from getting injured while skinning, deboning, or filleting your fish.

With all of the various knives available, it can seem like an overwhelming decision, especially if this is something you are just getting into. For your convenience, we have compiled a list of the top-rated options, and buyers guide with questions that fellow filleters often ask so that you can make an educated decision on the best fish fillet knife for you.

Why Use a Fish Fillet Knife?

There are clear advantages of using a fish fillet knife. Other knives are simply not meant to do a fillet knife’s job and are not designed for deboning or slicing fish appropriately. Fish fillet knives are made with skinny blades to skin fish without trouble and mess. The goal is to remove the fish’s scales and skin without mangling the flesh of the fish.

For fishers, the right fillet knife is essential to gut and prepare the fish for the kitchen. You cannot prepare most fish with a regular fillet knife, but for larger fish with tougher scales, an electric filleting knife might be the best option so that you do not hurt your hand or chip or break the delicate blade of the fillet knife. 

Safety measures should be taken when filleting a fish, and most fillet knives accommodate that need. Many fillet knives come with finger guards and other safety features to ensure you are adequately protected while you are in the process of filleting or skinning your fish.

Some fillet knives have the added option of being used as a boning knife, but the blade will become worn down much quicker, so they will need to be sharpened more often. In this case, you will want to invest in a good knife sharpener or purchase a fillet knife that has a sharpener included.

What to Look for in a Fillet Knife

You may or may not already know that filleting a fish isn’t an easy task, so the type of knife you choose needs to be appropriate for the job you are doing and serve the purpose you need effectively. With that in mind, here are a few things to look at when choosing a filleting knife.


When considering a fillet knife, you want to get the best knife for the job you want to do, but you also want to get the most value for your money. 

Prices vary significantly from moderate to high, and the amount you are willing to spend should correlate with the frequency that you are going to use the knife. If you are planning on using the knife occasionally, it probably isn’t worth it for you to spend a ton of money on it. 

Alternatively, if you will be using this knife consistently, you will want to invest so that it lasts a long time. You also want to consider what type of fish you typically prepare when choosing the proper fillet knife. You will not need a larger blade for a smaller fish, but if you prepare salmon or larger fish regularly, you need to adapt for that need. 

Be careful not to assume that the most expensive knife is the best knife. Our top choice is one of the least costly fish fillet knives out there, but the quality and job performance are stunning. More isn’t always better when it comes to price.

Blade Material

When choosing a fillet knife, you want to account for the jobs you will be putting the blade through and choose a sustainable quality knife. Most blades are made from high-quality stainless steel that is non-corrosive, which most people look for. You want to look at the blade’s durability, the flexibility, and how often you will need to sharpen it, and whether or not it is easy to do so. 

Handle Grip

What you should consider when choosing a fish fillet knife is a good handle grip. You will want a grip that allows you to control the cuts and guide the blade without too much effort or slipping. 

This is primarily important when the blade becomes wet while you are in the kitchen, but more so if you are using the knife while fishing. You will most likely gut the fish outdoors, and if it is raining, you will want to ensure that your hand does not slip while you are doing so or risk nicking yourself or inflicting a far worse injury on yourself. 

Conditions for preparing your fish, especially outdoors, will not always be ideal. Even if you prepare your fish in the kitchen, the fish’s innards will make your handle slippery, and you will need a rubberized or textured grip to help keep your hand firmly on the knife handle.

Blade Size

Most fillet knives come with blade sizes ranging from 4 to 9 inches, with the most common sizes being 4, 6, 7.5, and 9. You will want to choose your blade size depending on the type of fish you will be preparing with it. A smaller blade would not be a good choice for a larger fish, and likewise, a larger blade would not be appropriate to cut a small fish. Choose a blade size that works with the type of fish that you will typically be prepping.

For pan fry fish such as Crappie and Perch, you will want to choose a 6-inch blade typically, while you would prepare trout and bass with a 7.5-inch blade. You will want to opt for a 9-inch blade for larger fish like salmon to ensure you can cut through the fish easily without breaking or chipping it. If you find that you like to prepare various fish, it might be wise to consider purchasing blades of various sizes and have a few knives on hand.

Electric Fillet Knives

While not as commonly used, an electric filleting knife might be something you want to consider. If you often prepare large quantities of fish, an electric fillet knife will cut down your prep time and save your hands from overexertion. There’s no need to feel like you are taking a shortcut with an electric fillet knife, as many fishermen swear by them. The electric fillet knife is not for everyone, especially a novice who prepares fish only occasionally. Still, if you are a chef or work with large fish often, then the electric knife will save you time and energy.

Blade Flexibility

To check out blade flexibility, you might want to go to a knife store and check it out for yourself. If you do not know of any stores near you, there are several reviews online for fillet knives, and most of them will mention the blade flexibility. Blade flexibility is crucial as you need your knife to work around backbones and under the skin, which is difficult to do if the blade is too stiff. As most of the actual cutting is done by the broadest section of the blade, you will want to ensure the blade’s flexibility is closest to the handle and bonus points if the blade is flexible near the tip of the knife. 


The knife bolster is the thick part between the knife handle and the blade, which provides a smooth transition between the two. The bolster adds strength to the knife and durability and counterbalance, which is important since the handle is lighter than the blade. The bolster provides better balance and helps to improve control over the knife.

Some fillet knives have a finger guard on the bolster so that you can hold it more securely. If you are looking at Japanese fillet knives, which are usually of high quality and great for delicate fish, you will notice they do not have finger guards, so they require a different way of utilizing the knife.

Types of Knives

There is a difference between boning knives and fillet knives, which is essential because some knives claim to be appropriate for both. Boning knives are used for deboning a fish, while fillet knives are for removing bones along the skin from the fish’s meat.

You can use all boning knives for filleting in theory, but you cannot use all fillet knives for boning. You can look into fillet knives that can do both.

Boning Knife

The boning knife is used to remove the bones’ meat, whether for fish, steak, or chicken. You would use a boning knife over a kitchen knife to work around the bones for this delicate task. This will ensure the meat is sliced to perfection and not destroyed.

A boning knife is made of quality steel to work through thick bones and not become too dull. The blade is thin but not as thin as a fillet knife.

Fillet Knife

A fillet knife is used to remove the flesh of the fish from the meat. Oftentimes the fillet fish can also debone with fish that have soft bones and are smaller in size.
