Firstly, choose the type of sharpener you are going to buy. There are four types of knife sharpeners,

1.1 Sharpening Stones:

Sharpening stones are exceptional in pointing any shape or size of knife blades. They come in different grit surfaces, including fine, medium, and coarse grits, and they collectively help you gain a new and polished blade edge. You surely need to be extra careful with stones if you are new to sharpening knives.

1.2 Sharpening Rods:

Honing or sharpening rods are generally ceramic or steel rods that help give a perfect final touch to the knife’s sharp edge. These rods can regularly keep a blade edge sharp and rust-free. You should buy a honing rod even if you are buying any other sharpener as it will give you an ideally smooth knife edge.

After you know what type of sharpener you are going with, you can move on to other features.

2. High Quality

Quality is a must-have when buying a sharpener; the more the quality, the longer it will last. The blades of a good fillet knife sharpener are made of either tungsten carbide or diamond. These are the two best materials that make the edge abrasive, and that way helps in achieving a better knife sharpening angle in less time. Like the Chef’s Choice Trizor xv EdgeSelect, have 100% pure diamond blades with abrasive and fine settings all at once.

3. Safety and Ease of Use

Your safety comes first, so you should look for electric or handheld best fillet knife sharpeners with a rubber base. The rubber base/feet will prevent any movement of the sharpener while using it to ensure your safety, like the Presto professional electric knife sharpener. If you are opting for a manual sharpener, then look for one having a safety handle for your hand to avoid even minor cuts. Same as the Accusharp fillet knife sharpener, have an exceptional handle that makes it safe and easy to use.

4. Sharpening Stages

Sharpening slots and stages are essential part of the best knife sharpeners. Whether you are buying a sharpening stone or an electric or manual knife sharpener, opt for the one with two to three sharpening stages (fine, medium, and coarse settings). The rough grit helps in sharpening, while the fine one helps hone the edges. Like the Sharp Pebble sharpening stone, Work Sharp Guided Field Sharpener has the most acceptable and uneven surfaces.

5. Affordability and Deals

Q1: Can I sharpen my fillet knife with any sharpener? 

No, you cannot sharpen a fillet knife with any ordinary sharpeners. Fillet knives are thinner and softer than other knives and thus, need a more delicate blade space to point them flawlessly. The best fillet knife sharpeners like Presto 08810 and Chef’s Choice Trizor XV have adjustable blade sizes to fit the fillet knives perfectly. 

Q2: What is the best angle to sharpen a fillet knife? 

The angle of the fillet knife depends on the sharpening product. However, the most widely used fillet knife blade angle is 20o. And in the best manual fillet knife sharpener, the pitch is pre-set to a sharpening angle of 20o so that you can hold your knife at 90o to point it. 

Q3: How to ensure safety when sharpening a fillet knife? 

Safety should be your priority when using a fish fillet knife sharpener. Keep your hands away from the blades and knife, and keep your utmost focus on sharpening. Hold the knife and sharpener handle firmly with both hands and wear a cut-proof glove for extra safety. 

Q4: Which of the best fillet knife sharpeners is the most economical? 

There is not such a large gap in the prices of the best knife sharpener for fillet knives, including stones, rods, and fillet knife manual sharpeners.
