Buyer’s Guide

What is the best fillet knife? Let us answer this question in the buying guide below. Before your purchase, there are few features to pay attention to.


The two most common styles we encounter in filleting knives are Japanese and German (Scandinavian) styles. Together with similarities, there are some crucial differences:

Japanese Style

  • Features thinner blade and is lighter,
  • Single-beveled blade (sharpened on only one side of the blade),
  • The steel is often harder than German-style, making it sharper,
  • It is more suitable for making clean slices and chopping due to the lower angle of the blade,
  • Require more frequent sharpening to maintain the edge,
  • Prone to breaking and chipping.

German Style

  • The blade is thicker, so the knives are usually heavier,
  • Double-beveled blade (sharpened on both sides of the blade),
  • The steel is usually a little softer than the Japanese style;
  • It is better suited for the rocking type of chopping because of the larger angle on the blade,
  • It does not require frequent sharpening,
  • Not so prone to chipping and breaking.


This choice comes down to manual vs. electric fillet knife. Manual knives allow for precision cutting, usually have a narrow blade often curved to ease precision cutting. For most people, a manual filet knife is sufficient to meet their needs.

Electric filet knife uses a motorized handle that powers two serrated blades that attach at the tip. The blades oscillate back and forth in opposite directions to create a sawing action. They are quick but harder to control – usually are better for professionals who need to fillet a large volume of meat.

You also have corded models – powered by electricity and cordless – powered by a battery.

Blade Features

Blade material – stainless steel is the standard material for blades. It is a durable, strong, and corrosion-resistant material. In addition, it does not stain and is easy to sharpen. Some blades are even made of high-carbon steel that has exceptional resilience and sharpness.

Blade flexibility – a flexible blade will give you less waste because it is easy to maneuver along with the pin bones and backbone. It makes your cut more efficient.

Blade retention and sharpness – a blade with great blade retention stays sharp for a long time. However, the most trustworthy knives need sharpening to keep your fillet blade’s sharp edge from time to time.

Blade thickness – the general rule of thumb is – the thinner the blade, the more flexible it is. So you will want a knife that is between 2.5mm and 3.5mm thick, allowing you to work the contour of the meat with laser-sharp precision.

Handle Features

Handle material – three main materials used in making handles are wood, laminate, and plastic.

Wood is great, natural material that feels amazing in hand. However, it tends to hold onto bacteria and pale over time. Laminate is a mix of wood and plastic – it is more durable and far easier to care for.

Plastic is the cheapest and the lightest material that is also easy to care about. Still, it tends to crack a little, especially when exposed to high temperatures. Some handles even have a rubber coating for non-slip hold.

Handle design – handle should be designed to be comfortable to hold and ergonomic, which reduces the risk of repetitive strain injury. Having a firm grip before you start cutting ensures a lot safer, easier, and quicker filleting process. A good balance is also important to avoid overexertion. In the end, it should feel right in your hand.


The blade length goes with the size of the fish being filleted. A smaller blade has higher flexibility, so it is suitable for smaller fish. Therefore, we have:

  • Small blade length (from 4″ to 6″) is perfect for Mackerel, Trout, Walleye, Panfish, Perch, etc.
  • Medium blade length (from 7” to 8”) is perfect for Salmon, Pink salmon, etc.
  • Large blade length (from 9” to 12”) is perfect for Codfish, Tuna, Catfish, Halibut, etc.

Price Range

The price of professional fillet knives is high – it starts at around $10 to several hundred dollars. It comes down to your personal preference and your budget. The price usually depends on the brand name, quality of the knife, durability, and finish. Electric knives are expensive, so if you want to invest in a quality one, expect to spend more.

Best Way to Sharpen a Fillet Knife

There are several methods of proper sharpening of your fish knives. Here are some of them:

Method 1: Sharpening rod

This method is quick and straightforward. You have to slide the knife over the rod, keeping the right angle in between the blade and the rod. You may find it necessary to slide the knife in the direction away from your body. This tool is also appropriate if your knife needs just a quick touch-up after cutting few fillets.

Method 2: Electric sharpener

By far the simplest way to sharpen a knife. Whatever model of the electric sharpener you have, the principles are the same – you have sharpening and honing slots.

You will only need to pull the blade through the sharpening slot several times until you reach the desired sharpness. The honing stage is used for bringing back the edge of the knife before it becomes dull. Therefore, it is best to get in the habit of using the honing slots after the extended use of the knife.

Method 3: Sharpening stone

A little bit trickier method – you need a little practice because using it in the wrong way can destroy the thin blade of your fillet knife. The desired results lie in the right angle and technique of the sharpening.

This is done by sliding the cutting edge of your knife over the sharpening stone like slicing butter. The back end of the blade will have to be positioned slightly above the sharpening stone to easily slide the knife forward and make the edge very sharp.

Optionally, you can use a coin to position your knife at the right angle and position your fingers above the blade to slide the knife over the stone without cutting yourself. The process is done on each side of the knife until the edges are sharp enough.

Method 4: Accusharp tool

Using this tool to sharpen your fillet knife is simple and quick. Put your knife on a flat workspace, with the suiting side facing upwards. You only need to place the ‘V’ shaped part of your accusharp tool on the knife and start sliding the tool over the blade. Repeat the process until you are satisfied with the sharpness.
