There are, however, differences between fillet knives that you should be aware of before purchasing. We pulled together the ten best fillet knives on the market and some criteria for choosing which one will be the best fillet knife for your kitchen.
Quick Summary Of The Top 3 Best Fillet Knives
The Best Fillet Knife
1. Mercer Culinary Millennia Narrow Fillet Knife, 8.5-Inch, Black

The Millennia has an ergonomic handle that is built for both durability and to encourage less strain and discomfort for prolonged cutting jobs. This is one of the narrowest fillet knives in our review, and we feel as though the narrow blade can help to increase productivity when filleting meat or fish.
The grip has textured fingerprints to help keep your hand in place when working on more challenging to cut a piece of meat. The blade on the Millennia is made from high-quality Japanese steel, and it is effortless to sharpen.
The Mercer Culinary Millenia gives you everything you need in a high-quality fillet knife for a very fair price.

As most chefs will tell you, when filleting, you can set yourself up for some pretty ugly kitchen disasters. Your hands and the knife will have to work at some obscure angles to fillet varying types of meat properly. This makes the safety feature in fillet knives of the utmost importance.

The ergonomic polypropylene handle has textured points where you can place your fingers. This will allow for a much lower chance of your hand or the knife slipping and causing an injury. This knife even comes with a limited lifetime warranty.

Things To Consider Before Selecting The Best Fillet Knife For You
Now that we have filled you in on the best fillet knives on the market, you have to decide which one is best for you. With all the options out there, this can be a tough call. There are a few key features that you should look for before you ultimately decide which knife is going to be best for you.
What Is a Fillet Knife Used For?
A fillet knife is used to get between the bone and the meat of a fish or other piece of meat. The fillet knife is most often used when it comes to cutting fish, but there are other uses for the fillet knife as well. Some people find a great fillet knife that works for them, and they use it for many different cutting jobs in the kitchen.
There are a few essential characteristics of a fillet knife that are important to note. For starters, the fillet knife is usually between six and eleven inches long. Fillet knives must be flexible so that they can cut through a variety of thicknesses with ease.
The thickness of the fillet knife is usually quite thin, and the blade is generally made with high-quality stainless steel. The stainless steel will keep the knife from rusting, even when exposed to wet conditions.
The Fillet knife is most often found on a fishing pier. If you have ever done any fishing, you know that you must fillet the fish at the end of the day. Without the proper fillet knife, filleting a fish is long and tedious work. Having the right knife also makes fillet fish much less dangerous.
If your kitchen does not currently have a fillet knife, you are probably going to want to add one. Whether it means getting a chicken breast thinner or cleaning up your prized catch from earlier that day, the fillet knife is worth having around.
Length of Blade
The standard fillet knife blades are going to be anywhere from six to eleven inches. If you noticed, most of the blades on our review were around seven or eight inches. We feel like the seven to the eight-inch range gives chefs the most flexibility and control while keeping safety in check.
When you look into the very long blades, make sure that you are also considering safety features. Another thing to remember is that the longer blades can sometimes be challenging to maneuver. If you think you will be making a lot of intricate type cuts, the shorter blade is going to be the better choice.
Fillet knives are made very sharp. They need to be sharpened quite often as they tend to dull quickly. Each fillet knife that you look at will claim that they have a razor-sharp blade. All of these knives indeed start this way, but some will need extra maintenance as you use them.
The German Stainless steel knives seem to hold their sharpness the longest between begin sharpened.
Fillet knives are most commonly made with stainless steel material. The reason behind this is that the knives need to be durable, thin, and flexible as well. Stainless steel comes in many different grades, and this ends up being an excellent material for the fillet knife.
Another good thing about stainless steel is that it is usually more corrosion and rust-resistant. We still recommend drying your knife after use, but if you forget to, from time to time, you shouldn’t end up with a completely rusted blade.
Of course, the essential features of a fillet knife are the blade sharpness and the design of the overall knife. Depending on if you are using the fillet knife in the kitchen or as a fishing knife, there are some additional features that you may see offered in a fillet knife.
- Sheath: Not all fillet knives come with a sheath if your knife does not come with a sheath make sure you have an excellent place to store it
- Hole In Handle: You may notice that the handle of the fillet knife has a hole in it. The hole is for putting a string through so that a fisherman can tie it to their belt. If you are using a knife in your kitchen, the hole won’t be necessary, but it also won’t get in your way.
- Pointed Tip: If you end up having trouble starting your cutting a sharp tip on a knife can help get you going. Not all knives come with this feature, but it is an excellent option if you are using your fillet knife frequently.
The two main safety features to look for in a fillet knife are the handle and the sheath. The handle will help to make sure your hand does not slip while cutting, and the sheath will keep the blade protected from your hands between use. Fillet knives are sharp, and they can be dangerous.
Many people find that the shorter knives are a bit easier to control and work with. If you are new to filleting and want to ease into it, this may be the way to go.
The knives in our review range from less than $20 to over $150. As you probably know, knives can get very expensive. When it comes to how much is a reasonable amount to spend on a knife, we always say that you should consider two key points.
- How Long Will It Last?
- How Much Will You Use it?
If the product you are considering is going to be something that you use every day and it comes with a lifetime warranty, a higher price can undoubtedly be justified. If you have never owned a fillet knife and you want to try one around your kitchen, then the less expensive knife will surely do until you decide if this is a product you enjoy using.
Another factor to consider with the price is the features that are included. If you are getting higher quality steel that requires less sharpening, there is value in that. If you are getting a sheath with the knife, this may help to prolong the life of the knife and keep you and your family safe. Look for the features that are included and make sure they justify the price.
Many people wonder what the difference is between a cheap knife and an expensive knife. Most of the time, it has to do with the quality of the material. If you are a professional chef and you need a knife that gets very sharp and quickly slices than the better material and higher quality knives are going to make sense.
Care & Cleaning
For those that do not like hand washing dishes, the fillet knife is going to be something that you will probably end up replacing quite often. Every knife in our review recommends being hand washed. Hand washing a knife only takes a minute, and it will end up keeping your blade much sharper. Hand washing also helps to keep the handle in better shape.
Fillet knives will need to be sharpened from time to time, but the stainless steel material they are mostly produced with are easy to sharpen. If your knife comes with a sheath, be sure to use it. Not just for safety reasons but for storage purposes as well. Knives stored with a sheath in place will stay sharper longer.
A fillet knife is an essential tool in any kitchen. If you work with fish, it is a must, but it can be used on a variety of meat. People like the flexibility and maneuverability of the fillet knife. The stainless steel blades tend to be rust-resistant and should hold up for many years.
If you have been searching for a fillet knife for quite some time and you are overwhelmed by the choices out there, we can certainly understand. Some of the differences between the fillet knives are so subtle that you won’t know how to tell one apart from the next.
