Best Fillet Knife for Fish – Top Five for 2019

best fillet knife for fish


For many anglers, one of the most satisfying things is being able to slice through their catch cleanly and ultimately transform the meat into a delicious meal. While you can cut through a fish with a wide variety of cutlery, one type of knife that achieves this more quickly and precisely than any other is the fillet knife. Let’s look into the best fillet knife for fish!


Often confused with boning knives due to their similarity and sometimes overlapping functions, there are some significant differences between the two. For starters, fillet knives are usually thinner than their counterparts and are more appropriate for removing bones and skin from fish.


That being said, perhaps the most significant difference between a boning knife and a fillet knife is the flexibility of the latter. A fillet knife can conform better to the delicate meat of the fish and allow for a more precise cut and reduce wastage. Using the wrong knife to cut fish away from the bone can spiral very quickly – there is an increased risk of slicing your hand and wasting your meat. The wrong knife will also lose its sharpness very fast. Using a high-quality fillet knife will, therefore, help you avoid these potential hurdles and give you the desired results in the kitchen. But what makes for a quality fillet knife?





Choosing a fillet knife can be a daunting task especially since there are so many options available on the market that have similar characteristics. Here are the key points to keep in mind when looking for a fillet knife for fish.


  1. The blade

The blade is perhaps the most crucial part of any type of knife as it is located at the business end of this tool. As a result, you always want to examine the blade of a fillet knife before settling on one.


  • Type

Always go for a fillet blade that has a thin yet durable blade. Your chosen blade should be able to hold a sharp edge and also be the appropriate length for the fish that you are working on.


  • Flex

Flex refers to the ability of a knife blade to bend when subjected to light pressure. This is especially crucial for executing delicate cuts, such as when paying attention to the contours while trimming around the bones and fins or skinning the fish. The flex of a blade is usually determined by its thickness – an increase in thickness decreases the range of flex that a blade possesses.


Shorter blades typically have more flex as the small size fish you are working on need sharper cuts and tighter angles. Longer knife blades should possess a certain degree of flex as well, but it is not as significant as having it in a shorter blade. On both cases, the blade should bend when the tip of the knife is pressed down and pressure is applied. As the length of a blade increases, flex should be maintained through the entire blade, but length brings with it an added thickness due to the higher strength capacities that they need to exert.


  • Material

When it comes to the material of the blade, the best choice is stainless steel. High-quality stainless steel won’t warp, corrode, or tarnish after continued use, even in wet conditions especially when it comes in contact with saltwater. Particular types of steel such as 9CR offer an impressive blend of corrosion resistance, toughness, and edge retention. High carbon steel is also quite impressive as it is very easy to sharpen and also resilient. However, it has lower stain and corrosion resistance, thereby requiring more maintenance.


  • Construction

The design of a blade is another important determinant in its quality. A full tang knife features a blade that runs the whole length of its handle, whereas a partial tang knife has a blade that extends only partly, and it is usually hidden in the handle. A tang is the unsharpened part of the blade to which the knife handle is attached. Full tang construction essentially enhances the feel and balance of a fillet knife and also increases stability, strength, and control.


  • Length

Fillet knife blades range from 4-10 inches in length, giving you a wide selection to choose from. Blades that fall on the shorter end of the scale are ideal for use on smaller fish species such as crappies, sunfish, and yellow perch. On the other hand, if your catch typically consists of trout and eater-sized walleyes, consider going for 6 to 8-inch lengths. If you typically end up with bigger fish such as broad-shouldered pike and supersize salmon, you will want to go for 9 to 10-inch blades that will provide extra strength that is needed.


It doesn’t hurt to have at least two or three fillet knives of different lengths to ensure that you always have the appropriate size, but if you are comfortable with just one knife to serve you for various purposes, a fillet knife in the 7-inch category is a great and versatile option.


  1. The handle

Although the blade does the job in a fillet knife, the handle also plays an important role. You always want to go for an ergonomic handle that will fit comfortably in your hand and allow you to control the movement of the blade while keeping a firm grip on the knife even when you come in contact with water, fish slime, or blood. A well-made handle will reduce strain and fatigue during a prolonged filleting and cleaning process.  Most importantly, a good grip will also ensure safety.


Wood is a common material choice for the handle, but when it gets wet it tends to become very slippery and is also susceptible to cracking when it dries. Wood also soaks up unpleasant smells very easily, making it hard to clean. Hard plastic is tough, but it can also get slippery. Rubber grips are soft and less likely to slip out of your hand, but it tends to lack the rigidity required to control the knife. Therefore, consider going for handles made from a combination of materials such as rubber and plastic.


  1. The sheath

The sheath is often overlooked, but it is an important consideration as well as it protects those around the knife when it is in storage or transport. A plastic sheath is not only durable but also easy to maintain. Leather is durable and molds well to the shape of your knife, while nylon is very versatile.


  1. Electric vs. traditional fillet knives

When selecting a fillet knife, you can either go for an electric-powered knife or a more conventional manually operated model. Traditional fillet knives execute precise cuts and are ideal for extracting meat from gamefish such as panfish, trout, and walleyes. On the contrary, electric fillet knives require less effort to operate and are faster than traditional options, although they are also larger and heavier. There are two common categories of electric fillet knives, namely cordless and corded variants. Corded fillet knives offer more power and higher RPMs, but there is no use for them if there is no outlet. Cordless knives are especially useful when there is no charging outlet nearby, and you also don’t have to worry about the cord getting entangled around the blade.

With so many fillet knives on the market, it can be a little overwhelming to pick just one. That being said, there are some key qualities that you should always seek out when looking for a knife. For starters, a fillet knife should have a flexible blade that will allow you to maintain tight angles as you fillet. The material used to make the blade should be non-corrosive, stain-resistant, and durable. The size of the knife you go for will entirely depend on the size of the catch you are working on. The knife handle should be comfortable and non-slip to allow you to use the knife without worrying about it accidentally slipping out of your hand. Always go for a blade that runs the whole length of the handle because full tag construction generally enhances stability, control, and strength.
