In a hurry? My pick for best fillet knife sharpener is the Chef’sChoice 15 Trizor XV EdgeSelect Professional Electric Knife Sharpener.

There are few things as satisfactory for a professional or enthusiast cook than having a sharp, sharp knife. Not only do sharp knives cut better, but they’re also safer – it’s harder for a sharp knife to slip and injure you. That’s especially true for fillet knives, where you often work in slimy and slippery conditions when preparing fish to eat.

Unfortunately, it doesn’t take long for a new knife to lose its edge. For that reason, you’d be well-advised to always have a good sharpener at hand.

With that in mind, this guide will go over five of the best fillet knife sharpener products on the market. Additionally, it will provide useful information about knife sharpeners in general.

Let’s cut to it!

A Buyer’s Guide to Fillet Knife Sharpeners

Fillet knives are 4 – 12″ blades most often used to prepare fish for eating. Versatile even for your land animals, fillet knives are often used under tensions for cuts like slicing off fish scales.

You read our best fillet knife roundup here, but now we’ll cover what it takes to keep those knives sharp. (Also see our best fillet knife for saltwater fish roundup, featuring longer knives).

What to Look For in a Fillet Knife Sharpener

When you look for a fillet knife sharpener (or really, any knife sharpener), take the following factors into account:

Abrasion

In order to sharpen the metal, knife sharpeners use an abrasive material in their interior.

The more abrasive said material, the more powerful its sharpening action will be. Normally, sharpeners use diamond, polished ceramic, or tungsten carbide as their main abrasive materials.

Sharpening Stages

The best fillet knife sharpeners out there offer different sharpening stages, resulting in added flexibility and versatility.

While the coarsest stage is great for sharpening dull and blunt knives, finer ones are better for providing finesse and polish. Some sharpeners even include ultra-fine sharpening stages for touch-ups and delicate knives.

Size

Before you settle on a specific model, make sure it has the right dimensions for your needs. While they tend to be more portable, compact fillet knife sharpeners may not be compatible with larger knives.

Weight

Make sure to take a portable fillet knife sharpener’s weight into account.

Heavier sharpeners are often meant to be stationary, and their weight provides them stability and security when in place. Meanwhile, those lightweight sharpeners can be easily moved from one place to another as needed.

Safety Features

Dealing with knives and sharp edges can be dangerous if you are not careful.

To keep your fingers safe, the best sharpeners include security guards that prevent the blade getting too near to your skin. To avoid accidents due to slippage, some models also include rubber grip handles and non-slip rubber feet.

Slots

Simply put, the more slots your sharpener has, the more types of knives it will be able to properly sharpen. Typically, in order to suffice for both sides of the knife, fillet knife sharpeners have at least two slots for each sharpening wheel.

Cleaning and Maintenance

Whenever you sharpen a knife, it produces tiny dust-like metal debris.

For that reason, the best fillet knife sharpeners feature inventive ways to make the cleaning of that debris easier. At the very least, having a scrap metal collecting tray is a must as it prevents metal dust from accumulating elsewhere inside the device.

Additional Tips for Using a Fillet Knife Sharpener

Learn How to Properly Operate a Fillet Knife Sharpener

There is no doubt that using a sharpener requires less practice and skill than sharpening knives by hand or with a stone.

But before you dive in, it’s still important that you familiarize yourself with your device.

Be Careful With Heat

As you have probably noticed, using a sharpener on a knife generates quite a lot of heat

Unfortunately, if left unchecked, the heat can damage and even ruin a perfectly good knife. For that reason, be sure to let the knife cool if it’s getting too hot from the sharpening.

Mind the Pressure

When using a knife sharpener, be mindful of the amount of pressure you apply to the knife.

Unevenly applying pressure can mean some parts of the blade aren’t as sharp as others. And if you apply too much pressure, the knife can become damaged and even break. Even worse, you can hurt yourself if this happens.

Always Be Safe

At all times, remember that knives are dangerous tools that can cause a great deal of harm.

When dealing with knives, always be smart and responsible about it. Furthermore, when using a sharpener, make sure to take into account everything that the manufacturer has got to say in regards to safety measures.
