With so many options at your disposal, it can be a bit confusing to know where to start. The best fish fillet knife easily skins the fish and cuts along the backbone with precision.

A Simple Buying Guide To Determine The Best Fish Fillet Knife
The average person probably thinks that a knife is a knife! But as you can see, knives come in many varieties. Even when discussing the best fish fillet knife, the options are plentiful. Whether you’re a fisherman or you just love cooking fish, investing in a high quality fillet knife is a decision that will pay off in the long run. Not only will it keep you from ruining your dinner, having the right fishing knife or fillet knife will help keep you safe and protected when preparing your meal.
Before you buy, you’ll want to take several things into consideration. In addition to our list of the best fish fillet knives, we’ve put together a buying guide and some frequently asked questions. It’s very helpful to know what to look for in a fillet knife. You’ll also want to consider the knife’s primary purpose and use.
Advantages of a fish filleting knife
Any other kind of knife simply is not built to do the job of a fillet knife. Fillet knives are designed specifically to gut, slice and sometimes de bone fish. These knives have a special slim blade that skin fish without making a mess. The aim is to seamlessly remove the skin and scales without mangling the meat of the fish.
If you’re a fisherman, a fishing and filleting knife is essential. You need the right kind of tool to gut and prepare the fish for the kitchen. A larger fish with thicker bones or tougher scales might require an electric filleting knife to help you tackle the task without exhausting your hand or breaking your blade. And that brings us to safety. Because using the wrong tool is never a great idea, in the kitchen or elsewhere. You’ll notice many fillet knives have a finger guard or other safety features to help sufficiently protect you during the delicate process of filleting fish. Some fillet knives even double as a boning knife. Because fillet knives can take a beating, it’s a good idea to have a knife sharpener, and some knives even include them.
What to Pay Attention to When Buying This Product
Filleting fish can be difficult enough without adding the wrong knife to the equation. To ensure that you choose the best knife for your purposes, here are a few things to consider.
If you’re like most people, you’ll want to get the most bang for your buck when you set out to purchase a fillet knife. Prices range from modest to quite high, and the frequency with which you plan on using this knife should be taken into consideration. If you only occasionally cook small pan fish, you probably don’t need an advanced tool. If you cook fish weekly and make a wide variety of fish, you’ll want to choose something more versatile and durable.
Because your fillet knife is being used for some pretty tough work, the blade material is very important. You want to look for high-quality material that offers flexibility and durability at the same time. Another thing to keep in mind is whether it’s easy to sharpen. You’ll need to do this occasionally to keep your fillet knife in optimal shape. Many of the knives on this list are made from non-corrosive stainless steel and that is a recommended material.
Almost nothing is more essential in a solid fillet knife than good grip. You want to be able to glide through fish with ease and you want to do it safely. In order to be effective, your fillet knife should support you in this area. The handle needs to be comfortable, too. Otherwise, you’re unlikely to give it much use. When you’re fishing and/or preparing fish, conditions are wet and slippery. A good grip is of utmost importance so you don’t make a mess of the fish or nick yourself in the process.
Knife Blade Size
You will find that most fillet knives come in sizes between 4 and 9 inches. The most standard sizes are 4,6,7.5 and 9. Because fillet knives are designed to effectively prepare certain kinds of fish, the variety in sizes makes sense. Obviously, bigger fish will require a larger blade to get the job done. On the other hand, you won’t want to use a hefty knife for a small fish.
Pan fish like Crappie and Perch will do well with a 6” blade. Bass and smaller Trout are very popular fish and will require a 7.5” blade. But you’ll want to select the 9” blade if you’re a fan of larger fish like Salmon or Pike. If you’re used to cooking a wide variety of fish, you might find that several fillet knives are in order!
Electric Fillet Knives
Depending on your needs, an electric filleting knife might be just the tool for you. If you’re someone who regularly prepares batches of fish, an electric fillet knife is essential. In fact, many fishermen swear by their electric filleting knives. An electric fillet knife can help prevent hand fatigue since the torque is doing most of the hard work. While not everyone needs an electric fillet knife, they’re a must-have if you work with piles of fish or larger fish that have tough scales and large bones.
If you’re able to check your fillet knife in-person, you might want to take a look at the blade flexibility. Time and time again, you’ll see reviewers mentioning the flexibility of a fillet knife. Flex is important because you need your fillet knife to maneuver well around backbones and under skin. Most of the work is performed by the wider half of the blade. As such, you want to select a fillet knife with 15-20% flex by the handle. Even better if there’s slight flex at the tip as well. If you can’t study the knife in person, just look for reviews and descriptions emphasizing a flexible blade.
