Sure, most folks will agree that filleting is a task that requires a dash of finesse but in truth, it’s really simple when you have the right tools at hand. Enter the fillet knife.
Whether you’re a seasoned outdoorsman or a savvy home chef, a fillet knife, also known as a filleting knife, is a must-have for anyone who enjoys fishing for food or simply cooking meat at home. With its strong yet lightweight blade, the fillet knife is perfect for separating the flesh from the bone, making sure no meat goes to waste. And while most people will use it to remove bones, scales, and skin from fish, some fillet knives will allow you to effortlessly bone poultry, wild game, beef, and even delicately peel fruit.
If you’re new to the world of fillet knives, then you’re in for a treat. Come with us on this marvellous trip through the subtleties and nuances of one of the handiest knives ever invented.

1. What To Look For In A Fillet Knife
When purchasing a fillet knife, you want to invest in a durable quality knife that will last a long time and be your ally in the kitchen as well as on your outdoor adventures. Cheap knives usually lose their edge pretty quick and no amount of sharpening will be able to bring them back to life, resulting in early disposal.
That said, if we’re getting into the minutiae of fillet knives, there are a couple of factors to be taken into account before making your purchase:
It is imperative that you get a fish fillet knife with excellent blade retention so it stays sharp for longer periods of time. A blunt blade will not only not do the job but it could also expose you to kitchen accidents, compromising both your integrity and the success of the food prepping process. However, even the most trustworthy knives will need a sharpening from time to time.
Regardless of your sharpening method of choice (whetstone, sharpening steel, electric knife sharpener, etc.), make sure you check out our tutorial on how to sharpen a knife here to keep your fillet blade’s sharp edge.
Your fillet knife’s material is also very important. Since fillet knives are most frequently in contact with wet materials, we strongly suggest you get a stainless steel knife with added chromium to prevent corrosion and extend your fillet knife’s lifespan. A corrosion-resistant, stainless steel blade is a must.
Fillet knives should be flexible in order to easily maneuver around bone, muscle, and connective tissue. The general rule of thumb is, the thinner the blade, the more flexible it is, allowing you to work the contour of the fish with laser-sharp precision. In terms of thickness, a fillet knife should be 2.5-3.5mm at the spine (or less). So yes, a thin blade will get you places.
The handle of a fillet knife can come in several shapes and forms, with materials ranging from wood to plastic and rubber. Like we mentioned in point 2, the humidity of the materials you’re working with is a key factor and you should always look out for a handle that’s both ergonomic and corrosion-resistant, guaranteeing a tight grip and optimal durability.
Make sure you clean your fillet knife blade after every use and store it in a dry place. It’s also important that you only use your fillet knife for filleting - an irresponsible use of the knife could eventually result in a blunt blade, much to your dismay.
There are basically two types of fillet knives: manual or electric. Both will do the job just as well but electric fillet knives tend to be larger, heavier, and more expensive. Also, an electric fillet knife requires a power source, either from a rechargeable battery or a plug-in, and that can become a problem when you’re fishing or hunting outdoors so a fixed blade is clearly the optimal choice. For this reason, we suggest you try to stick to manual fillet knives as they are more portable, lightweight, and generally cheaper. A folding fillet knife is a great example of this type of fishing knife.
The sheath is also an important part, as it plays an essential role in the conservation of your fillet knife. There are a wide variety of materials available, such as leather, nylon, and plastic. Yes, a leather sheath definitely looks cooler than the other options but it can soak up moisture and end up reducing your fillet knife’s lifespan. Our recommendation is a quick-drying plastic sheath that has plenty of ventilation and room for draining.
Note: When using your fillet knife in the kitchen, it is of absolute importance that you not only master the proper technique but you also look cool while doing it. But don’t worry, we’ve got you covered. Check out some of our fashionable aprons right here.

3. What Is A Fillet Knife Used For?
The main goal of using a fillet knife is to obtain precisely cut pieces of boneless meat, also known as fillets, from a big fish or chicken. For this purpose, the fillet knife features a highly-flexible trailing point blade that curves upwards from the handle to the tip, making it easier to produce smooth, precise cuts.
This flexibility is what allows the knife to cleanly separate the meat from skin, bone, and sinew, leaving you with a set of lean fillets ready to be thrown to the grill.
4. What Is The Difference Between A Fillet Knife And A Boning Knife?
While they overlap on certain tasks, the fillet knife and the boning knife are two entirely different beasts.
The boning knife, as you might have guessed, is generally used to remove the bones from meat and fish. Despite possessing a certain degree of flexibility, they’re usually stiffer than fillet knives. With a blade length ranging between 5 and 7 inches, boning knives are also thicker and can easily debone a wide array of meats.
On the other hand, the purpose of the fillet knife is a bit more specific. Specially conceived to work with more delicate meats, their sharp blade generally falls somewhere between 5 and 9 inches and it’s way thinner and more flexible than other knives, making it the perfect tool to descale, de-skin, and de-bone smaller fish in a matter of minutes.
5. What Kind Of Knife Do You Use To Cut Fish?
I’m gonna mention the obvious here but when cutting and prepping fish, you want to make sure none of the bones get into the final product. That could end up costing you or one of your guests a trip to the ER. That’s why you should always use a fillet knife as the starting point of your fish cooking process.
If you’re into sushi, there’s also a whole host of Japanese knives you can check out, including the Yanagiba, which is a staple of Japanese cuisine and is commonly used to prepare sushi and sashimi.
