What is a Fillet Knife?

You may be asking yourself what exactly a fillet knife is, and how it differs from other kinds of knives you’d find in kitchens today.

A fillet knife is very different when compared to the average kitchen knife. The biggest difference is in the blade. On a fillet knife, the blade is thinner, lighter, and more flexible than the blade you’d find on other kinds of kitchen knives.

This is because a fillet knife is meant for the delicate work of separating the flesh of a fish away from its small bones. The flexible blade is needed to make cuts that require a high level of precision, such as removing bones and scales or cutting the skin away from a fish.

Though a fillet knife is typically used by chefs and home cooks when preparing fish, it can still be used for other delicate kitchen work! These knives can be great for cutting vegetables and fruits, they are precise enough to cut intricate shapes, and they can expertly remove peels. If you want to make decorative, standout cuts on your fruits or veggies, a fillet knife can help.

Fillet Knife Buying Guide

Before you purchase a fillet knife, there are a few key factors you’ll want to keep in mind. Consider the following before you buy a fillet knife:

Fillet Knife Size

The size of the fillet knife you purchase will depend on what you plan to use it for. Typically, fillet knives can be found anywhere between 4 inches in length and 9 inches in length. The size of the knife and its blade length will depend on the size of the fish you are working with.

If you’re planning on cooking bigger fish (for example, a whole salmon) you may want to go for a knife larger in size. You’ll need a longer fillet knife blade to cover the surface area of the whole fish for tasks like removing skin and cutting out bones.

However, if you’re working with smaller fish or delicate fish like scallops, a knife of smaller size can be more useful. They can offer the precision that is needed when handling delicate, small fish.

If you’re unsure of what to choose, it’s best to buy a knife somewhere in the middle. The average fillet knife can come in around 7.5 inches and is a good “all-around” size, adequate for most fish. To get the most use out of a fillet knife, go for the average 7” size unless you’re positive you’ll need a larger or smaller size.

Fillet Knife Blade Material

The material of the knife blade matters a lot when it comes to fillet knives, due to the delicate nature of the blade. If your fillet knife blade is made of cheap fillet knife material, it can very easily become rusted, warped, or damaged.

Though fillet knives need a strong material, they still need a certain degree of flexibility. Your knife should be built to last with a sharp blade, while still offering the flex that makes a fillet knife good at what it does.

When shopping for a fillet knife, try to find a blade that is made of stainless steel or carbon steel. Stainless steel is a strong, lost-lasting material that should resist wear and tear the best.

Fillet Knife Handle

Many shoppers don’t consider handle material when looking at a filleting knife, but professional cooks know it can make a huge difference.

When working with a fillet knife, you’ll want an ergonomic handle that can give you the comfortable grip necessary to accomplish delicate, precise cutting. A great blade paired with a great handle will make working with your fillet knife effortless.

On the market today, you are most likely to encounter plastic and/or rubber as the material of choice for knife handles. In fact, for some cooks, plastic is becoming preferable to wood handles, which used to be the more popular choice.

Wood can lead to slippery mistakes, as it can get wet easily and lead to handling errors. Wood also tends to absorb the smells of the foods it’s handling, making it a bad choice for a fillet knife, as they’re used for fish. (Of course, there are great varnished wood handles out there that can avoid this issue.)

A plastic or rubber handle will resist absorbing smells, and of course, will be way easier to sanitize and clean as they don’t soak up anything. Rubber is especially useful for providing a good non slip grip on the knife. If you’re a beginner, plastic and rubber handles are the best choice to make.

Fillet Knife Accessories

Depending on your usage of your fillet knife, you may want to invest in an accessory or two. The most common accessory people pair with a knife purchase is a knife sharpener. If you don’t have one already, consider buying one alongside your new fillet knife. To perform its delicate work, a fillet knife needs to maintain its sharp edge.

Some fillet knives also come with sheaths, which can make them useful to take on the go. While most chefs would keep a fillet knife in their regular tool kit, a fillet knife is a popular accessory among those who like to fish.

When buying individual fillet knives, you’re likely to come across knives that come with a sheath and are built for travel. They’re also great for edge retention, keeping your fish knife a sharp knife.

If you’re planning on an outdoor adventure where you’ll fish and cook what you catch, finding a knife that comes with a sheath can be super useful. However, if you’re sticking to cooking in the kitchen, it may not be necessary.

Electric Fillet Knife

You may be familiar with the idea of an electric turkey cutter, but did you know there are also electric fillet knives? Technology has taken us far with the invention of the electric knife!

An electric fillet knife can be a great choice for those looking to make the fish cutting process truly effortless. If you’re in a professional kitchen cutting fish all day long, an electric fillet knife can help you save a lot of time, cutting fish with ease.

Some electric fillet knife models need to be plugged into a wall, where others are rechargeable or are battery-powered. There are tons of variations to fit your kitchen and cooking style. While some people like to stick to the classic, non-electric models, there’s no shame in going this route. Every cook is different, and electric tools can be a huge help for those looking to fillet in a much easier way.

Fillet Knife FAQ

Still got questions? Here are some frequently asked questions when it comes to purchasing a fillet knife.

What is a fillet knife for?

A fillet knife is a delicate knife used most often for skinning, de-scaling, de-boning, and filleting cuts of fish.

What size fillet knife do I need?

The size of the fillet knife you use will depend on the size of the fish you are cutting. Knives between 4”-6” are best used for small fish like perch or mackerel. A 7”-8” fillet knife is great for medium-to-large size fish like salmon or trout. Larger fillet knives that are 8” plus in length are best for large fish such as tuna.

Should I get a German or Japanese fillet knife?

When shopping for a fillet knife, you’ll run into both German and Japanese-styled fillet knives. German-style knives are known for having a double-beveled blade, and they are usually a little bit thicker than Japanese styles fillet knives. A Japanese fillet knife is a much thinner style blade, with a single-beveled blade.

The main difference comes down to working style. A Japanese fillet knife is better for small, precise work. If you’re looking to make fine, precise, clean cuts it’s a great choice. However, for everyday chopping where you need a bit more strength or force for cutting through bones, a German blade is best.
