Things to Consider
There is more to buying a fillet knife than just walking into a store and picking one that catches your eye. Since it costs more to invest in a fillet knife than a regular knife, it’s best that you make the right choice. This section contains all the important information you need to know before buying a fillet knife, including; what a fillet knife really is, how to use one, and the features to consider before choosing one. You will also learn how to care and maintain a fillet knife for an excellent long-lasting performance.
What is a fillet knife?
A fillet knife is a special kitchen knife used for filleting. It belongs to the boning knives family and is highly flexible to give good control for filleting. Its blade is super-sharp and long enough to cut smoothly any size of fish, including tuna, catfish, and salmon, among others. Its flexible blade can skin, cut or debone fish without sparing any edible parts.
The flexibility of a fillet knife depends largely on its length, width, and thickness. It is designed to bend easily around hard surfaces, and that’s why it efficiently removes cuts of fish. There are multiple variations of fillet knives in the market with different capabilities, designs, and dimensions. Thanks to advancements in technology, we even have electrical fillet knives, which are much faster and more convenient than the regular fillet knives.
How to use a fillet knife?
For you to make the perfect cut of fish, you must use the best fillet knife. Here is how to make a perfect fillet with a fillet knife:
First off, descale the fish using the back of the blade.
Then you can go ahead and remove the fins.
You can then use the tip of the knife to remove the skin of the fish.
Next, you remove the entrails and rinse the fish with water.
To start filleting, use the knife to cut the fish lengthwise.
Ensure you cut both sides to delineate the fillets.
Then use the flexible blade to remove the fillets from the spine gently.
Repeat on the other side to get the fillets.
Some fillet knives can be used for other functions other than filleting like deboning chicken and meat or cutting bread. Whatever you choose to use the fillet knife for, always ensure you clean it and dry it before storage.
Features to consider when choosing a fillet knife
There are certain features that you have to put into consideration before choosing a fillet knife to make the right choice. They include:
Electric vs. non-electric knife
Depending on your needs and budget, you can choose either that suits you best. An electric knife is a better choice for heavy-duty work. If you have a large pile of fish to fillet almost daily, then an electric fillet knife could come in handy to save you time and energy. It is much sharper and faster than a regular fillet knife but also more complicated to use and heavier in weight.
A non-electric fillet knife, on the other hand, is lightweight and very straightforward to use. It is a more suitable choice if you rarely eat fish or do fishing activities once in a while. They can be used both at home and for commercial purposes. Contrary to popular opinion, they are not cheaper than electric knives. Some non-electric fillet knives are more expensive than electric models.
Different knives have different types of blades. Some like the American Angler PRO Electric Fillet Knife reviewed above are serrated and don’t need any sharpening while others have a smooth single or double beveled edge. Also, some are bolstered for great balance while others are not.
Most fillet knives have long, ultra-thin blades with a clip point. The clip point aids in cutting the hard-to-reach places giving you more control when you are skinning, deboning, and cutting fish.
The blade design does matter as it determines the knife’s level of accuracy in making intricate cuts. A fillet knife with a more pronounced upward curve and a curved tip allows you to make longer, steadier and more precise cuts. However, this design makes it less practical for use in other cutting situations.
Also, some knives have double-beveled blades, while others are single beveled. Double beveled blades are versatile, much easier to use, and they make intricate fish cuts while single beveled blades require some skill but are much sharper.
Fillet knives have blades with varying lengths. They range between 4 and 9 inches. The standard sizes are usually 4, 6, 7.5, and 9 inches. These size variances are usually in correlation to the size of fish they are used to cut. Bigger fish like pike and salmon require a longer blade for efficient cutting, while smaller fish like perch and bluegills require a short blade that is easy to handle.
It is safer to buy an all-around fillet knife that can handle various fish sizes. A 7.5-inch blade will allow you to fillet small and large fish satisfactorily without much struggle. However, if you can afford it, nothing beats the efficiency and ease of use that comes with having specific blade sizes for different knives.
You must have noticed the price variations among different fillet knives. The price variations are primarily based on the blade material of the knife.
A good quality blade should be made from a hard metal for added durability and still be flexible. You can know how hard metal is by checking its rating on a Rockwell scale. Go for a fillet knife with a Rockwell scale rating between 55 and 62
High-end fillet knives are made of high-quality stainless steel and other mixed metals that are resistant to corrosion and provide the necessary flexibility. They are also easy to sharpen and hold their edge longer. Low-end fillet knives, on the other hand, are made with a soft material like carbon steel, which is difficult to sharpen and lose their sharp edge pretty fast. However, they offer excellent flexibility.
The knife’s handle contributes largely to you having clean cuts with less effort. A well-built handle should offer a secure grip, comfort, and good execution to allow you to fillet safely and effortlessly. Knife handles come in different designs and materials. The most common materials used are wood, plastic, and rubber.
Wood handles have the best aesthetic appeal and are long-lasting, but they tend to soak up the smell of fish, thus a bit hard to clean. They can also get slippery in wet hands. On the other hand, plastic and rubber are much easier to clean, and they don’t harbor any fish smells. They also offer good traction and are more long-lasting.
The overall size of the knife is determined by the blade length and the size of the handle. Once you have picked a suitable blade size, consider the size of the handle. Go for knives with large or medium-sized handles that can be handled by people with varying hand sizes, assuming that you are not the only one who will be using the knife.
Choosing an appropriate fillet knife size also depends on where you intend to use it. A smaller knife would be much easier to bring to your outdoor adventures as it would easily fit in your luggage.
This is another crucial factor. The weight determines how easy the knife will be to use. You have to try a few knives to find your ideal knife weight. Go for a lightweight model as it will give you better control, allowing you to maneuver more skillfully to make the best cuts.
Most fillet knives come with a sheath for storage. It is always good to keep your knife covered when you’re not using it to protect its blade and prevent any accidental injuries. The cover is much handier when you need to use the knife outdoors.
Some fillet knives come with their own sharpeners to keep the blade sharp and dandy. It saves you from buying a separate knife sharpener when your knife loses its sharp edge.
Boning knives and fillet knives tend to have the same function, but they differ in their build. Boning knives have stiffer and shorter blades to tackle the tough beef, pork, and poultry meat. Filleting knives, on the other hand, have longer blades that are highly flexible to slice fish along the backbone and under the skin.
You can use either an electric knife sharpener, which is pretty straightforward to use, or a sharpening stone or rod. When using a whetstone or a rod, start slowly by striking your knife’s edge against it at a 12 to 15-degree angle then increase the speed gradually.
Nothing can give you the best fish cuts than a goof fillet knife. In case you have decided to get a fillet knife, and you are unsure of how to choose the best one, the information on this guide should help you find your best match for sure. Also, you would never go wrong with either of the knives we have reviewed above in detail.
