How To Choose The Best Fish Fillet Knife

If you enjoy eating fish, you may be unsure which type of fish fillet knife is best for you. There are various options to choose from, making the process very confusing. The first factor to consider is whether you desire an open or closed knife. This means you can have a handle attached to the end of a pull-close handle. These fillet knives are referred to as folders and are available in various designs. Let’s examine some of the most popular styles and types to assist you in deciding. 



Selecting a fillet knife is not simple. They are available in various sizes, shapes, and designs, with numerous options to consider. Consider the species of fish you’ll be filleting as an essential factor. For cutthroat fishing, you can choose a small, lightweight model, or you can go all out and purchase one designed for larger fish, which will cost a bit more. Before purchasing a knife sheath, a few essential characteristics must be considered. 

A fillet knife made of carbon or stainless steel will perform admirably. Additionally, there are those made from a combination of these two metals. A good fillet knife will have a six-and-one-quarter-inch version, longer than most available sheaths. This enables the fisherman to get a better sense of the size of the fish they are pursuing. When it comes to the sheath’s additional features, you will want to spend the most money unless you are a fan of expensive electronic gadgets. 

When cutting fish, the grip will be utilized most of the time. Various handles are available, including those with double-thumb grips and single-thumb clasps. Some fillet knives offer both a double-thumb grip and a single-thumb grip; this is typically more important for the fisherman who primarily uses their knife for filleting. If you are like most anglers, a single-thumb grip will suffice, but a double-thumb grip is preferable for tough tackles. There is also a line of collapsible fillet knives that fit in your pocket and have an electronic or wire hook to facilitate retrieval. 

Due to their additional features and weight, electric fillet knives are typically more expensive than standard knife brands. However, you get what you pay for, which is why most professional fishermen prefer knives with stainless steel blades over imitation blades that may rust after a couple of uses. Also, your winning score will increase significantly if you fillet a large or small fish. This is because it simplifies your fishing experience by allowing you to remove the fish from the water without fighting for every inch of its body. To get a good feel of a large fish, you must wrestle it in, which is, frankly, not very comfortable. With a small fish, however, you can grab the fillet knife with both hands and begin cutting. 

The most important thing to remember about fillet knives is that they must be sharpened frequently. This may sound not very easy, but it’s relatively straightforward. When I know I won’t be able to sharpen the knife myself; I usually keep one sharpener in my kitchen. I find that a Mercer culinary millennia fillet knife is ideal for this task due to its strength and durability. I typically keep it in my cutlery drawer, but it comes in handy when craving a fillet. I rarely use it for cooking, but occasionally I clean fish at home, so I don’t waste food. 

Finally, is the dreaded 9-inch bubble blade sheath. If you’ve never been afraid of open blades, this is the knife for you. If you intend to fillet salmon, trout, or even swordfish, a fillet knife with this blade type is the best option. I would not recommend using one of these on any other type of fish due to how easily it cuts through the spine. 


Blade Material 

If you intend to purchase a high-quality fillet knife, you should be aware that the fillet knife can have different types of blades, such as the paring knife and the serrated knife. There are so many kinds of fillet knives on the market that it is difficult to find one that fits your preferences and budget. Therefore, you must conduct research before making a purchase. Check the material composition of the fish fillet knife as a primary consideration. 

Typically, the material of the paring knife is the most common. It is crafted from the highest quality wood and features a straight edge. However, if you want to purchase a fillet knife that is long-lasting and functional, you should select a paring fillet with carbon fillets. Carbon fillets do not have sharp edges, so you can confidently maintain the sharpness of your fillet knife. 


Since a fillet knife will constantly be in contact with food, you should choose one that feels comfortable in your hands and is sturdy enough to cut without any issues. 

Your decision should also be influenced by how frequently you intend to use your fish fillet knife. Some prefer the handle with a smoother surface, while others will be more at ease with a heavier, more solid grip. You will ultimately decide based on personal preference and what you have been able to handle up to this point. You should conduct online research to determine the most popular brands and styles. 

Blade Length 

The following consideration should be the length of the knife’s blade. The reason for this is readily apparent. The longer the blade of a fish fillet knife, the thicker and more durable its edge will be. 

There are also a variety of handle lengths available for fish fillet knives. There is a wide variety of handles, from simple to highly ornate. The material used for the handle is another crucial factor that must be considered. Some individuals prefer wooden handles, while others favor carbon fiber. The decision of which fish fillet knife to purchase depends on your personal preferences and intended use. 


If you’re looking for a good fillet knife, you should look for one with a good blade and handle and a good handle. Some people prefer a knife with a straight handle, while others prefer one with a curved blade. The price of a fish fillet knife will vary based on the materials used in its manufacture. These fillet tools are typically available at sporting goods stores and department stores. 

If you frequently shop online, you may be able to find a fillet knife for a much lower price than in a store. Numerous websites sell tools and equipment at competitive prices, and some offer meager prices for such items. Ensure that you purchase an item of high quality and not a low-cost imitation of an expensive tool. This will assist you in deciding where to buy your next fish fillet knife. 


Bigger fish require a longer blade, due in part to the wider girth and extra surface area you will be faced with. Smaller fish, on the other hand, require a shorter blade for easier handling and less overkill. For those that target panfish (crappie, perch and bluegills) a 6-inch blade would be an optimum length.

fillet knife is a great tool to cut fish such as salmon or trout. The difference between a fillet knife and a normal kitchen knife is the thickness and flexibility of the blade. A fillet knife is thinner and more flexible and hence makes it easier to make precise cuts along the spine of a fish.

Fillet knife blades are made very thin, approximately 2.5–3.5 mm at the spine, so that they can still bend and flex and maintain an edge. If the knife were hard enough to maintain an edge and the blade was thick, the knife would not bend enough to remove the skin from a fillet or work around intricate rib bones.

Santoku knives excel at slicing, dicing, and chopping. The super-sharp blade facilitates precision and versatility—this is a knife that can fillet a fish as well as it can chop an onion.

Santokus are most often used for chopping, dicing, and mincing. Because of their precision edge, they’re especially useful for julienning thin slices of vegetables and meats. The wide blade associated with a Santoku also makes it useful for “scooping” food off of a cutting board and moving to a Saute Pan or other dish.

If you’re looking for a knife to perform fine cuts of butchery for bone in-pieces, you need a boning knife. It’s a tough job, but the boning knife is specifically designed to get it done. Meanwhile, a fillet knife is meant to be used to separate meat from bone and skin, especially for fish.
