Fillet Knife Buyers Guide And Features

Before you go out and buy a new fillet knife there are a few things that you should consider.

The Blade

The blade on a fillet knife is probably the most important part of it, as this will determine the type of cut you will be able to make and how clean the cut will be.

For fish fillet knifes, you should make sure the blade you’re choosing is corrosion resistant, as being in wet environments - particularly salt water - can affect the performance of the blade.

A stainless steel blade can be a good choice and they are quite common on fish fillet knives and are usually corrosion resistant.

Handle Comfort and Grip

When you’re using your fillet knife, having one with a comfortable grip and handle can make the process of slicing and dicing a lot easier and quicker.

Particularly when you’re out fishing, you might often be using the knife with wet hands, which means a non slip grip may be essential for you. If you’re wearing gloves you should also make sure that you have a strong grip on the handle before you start cutting.

Knives comes with a range of different handle materials, from traditional wood to rubber or plastic. You may find it’s a matter of personal preference which handle material you choose. Just make sure that it’s comfortable for you to hold while you’re cutting and consider your slicing conditions.

How To Fillet A Fish

Size Matters

You may not think size is important when it comes to choosing a knife; just as long as it’s sharp, right? Well, actually, choosing the correct size of knife and blade can play an important role in determining how easy it is to cut and fillet a particular fish. And it all basically comes down the type of fish you plan on catching.

Blades come in various lengths, with each length suited for a particular type and size of fish. Not surprisingly, the shorter blades are more beneficial for using on smaller fish, such as crappie, or where you require more precision cutting.

With trout or bass, you may find it better to use a medium sized blade, roughly around 7 to 7 and a half inches.

The larger sized blades are often better suited to larger fish, so keep that in mind when you’re choosing yours. Also, you should consider the size of the knife when you think about your storage or transportation options. If you’re short on space, a folding knife might be a good option.

Strength

As well as the size of the blade you will also want to consider its strength to make sure it’s able to do the job that you want it to do. Fillet knives come in a variety of blade thickness levels.

This means the thinner the blade you choose, the more flexible it should be. A flexible knife can be handy for using on smaller fish and for removing bones, but may not be as good at slicing larger fish as there may be less strength in the blade and too much flexibility.

Electric Fillet Knives

It’s also possible to fillet fish with an electric knife, which could come in handy if you’re trying to fillet a lot of fish after a successful fishing trip, as it can be quicker.

Many electric knives will also let you change the blades, so you should be able to use specific blades for different cutting purposes. This can be a good idea if you fish in different areas and catch a variety of different species of fish and therefore need several knives.

FAQs

What Size Fillet Knife Do I Need?

This will mostly depend on the size of the fish you plan to fillet. The smaller the fish, the smaller the blade you’re likely to need. Smaller blades can allow you to cut at more delicate angles.

However, if you’re looking for more of a one size fits all, a medium sized blade of around 7 inches can be a good choice.

How Do I Sharpen The Knife?

Because the tip of your fillet knife is pretty important, you need to remember to sharpen it too.

So unlike sharpening other types of knives, it can be useful to sharpen it in the opposite direction, with the tip hitting the stone first, before the rest of the blade.

How Do I Use The Knife?

In order to give a proper description, a whole article might be required. It can be useful to slope the blade sideways as you cut, allowing the blade to cut along the spine.

The flexibility of the knife should let you maintain an angle with the blade to get a precise cut.

Can I Wash The Knife In A Dishwasher?

Yes, however, this can damage the blade and handle over time and can cause your blade to go blunt.

Can I Just Use A Pocket Knife Or Kitchen Knife To Clean A Fish?

Fish filleting knives are designed with the delicate meat of a fish in mind. Other types of knives are not, which means a kitchen knife or pocket knife may not be able to cut as precisely as a fillet knife.

These types of knives will also generally not be as flexible so you may not get the desired results if you use a kitchen knife or pocket knife.

Conclusion: Cleaning Up

Now that you’ve read about the various different fish fillet knives that are out there, you should have a better understanding of your own needs. If you know where you plan to fish and the particular species that you plan to catch then you should be able to narrow down your knife options.

If you’re unsure, perhaps an electric knife might be the way to go. As long as you consider how you plan to power it while you’re beside the water. However, a medium sized knife may also be the most versatile if you’re planning on fishing in lakes and rivers and catching medium sized fish.
