What is the Best Fillet Knife?
When looking for the best fillet knife, you want to start with the blade. A stainless steel blade that is cold-tempered and has a high carbon rating is one that will be lightweight, will stay sharp long enough to tackle a large job, is easy to sharpen, and is resistant to stains and rust.
This type of blade will help you have perfect control whether you are working to get the meat from around a bone in one swipe or deboning and filleting a delicate fish.
The blade will go into the handle, which will allow you to put force on the fillet knife without worrying that it will break and it adds to the durability. The handle will be non-slip for control and safety. You want a knife that helps you do a great filleting and boning job easily.
Things to Consider in Buying Fillet Knife
When choosing your fillet knife, there are various factors to take into consideration.
The flexible blade is one of the most important aspects of a fillet knife because a flexible blade will be able to go into a thick cut of meat without breaking. Good flexibility also makes it the best fillet knife for fish. Flexibility also creates a better control for the user and will allow you to get the meat closest to the bone.
When deboning meat or fish, and cutting large quantities of meat, things will get messy and slippery. If you put your full force into the handle of the fillet knife and it’s slippery, you are likely to cut yourself or make a mess of the fillet or boning job.
A textured gripping handle helps to take care of the possibility of slipping and gives you precise control. It’s also important for the fillet knife’s blade to go all the way into the handle because it is less likely to break with force and will last longer.
A straight blade design with the curved cutting edge give you a better design to get close to bones, and it is much more useful for intricate areas with one pass.
- This keeps the meat in one piece with clean cuts. You will be able to debone a fish in one swipe, making it a breeze to debone, clean, and perfectly fillet your delicate fish.
Most fillet knives are stainless steel, but as a buyer, you want to pay close attention to the type of stainless steel used because not all are created equal. Cold tempered steel with a high carbon value has the best quality.
The high carbon knives usually weigh less, are more durable, and they allow you to use the fillet knife on any cut of meat you want. By design, the blade is naturally rust and stain resistant. You do want to take care of your knife properly, which is generally a hand wash instead of running it through the dishwasher.
The recommended best size for a fillet knife is 5 to 6.5 inches for removing bone from the most delicate cuts of meat. This size will make it easier to control, but it won’t hold you up from doing your task. It also makes it lightweight for ease of handling with larger jobs.

There are many knives on the market to choose from, and prices will vary widely. The temptation to purchase a knife by price will be there, but a cheaper knife will cost in the cuts.
A higher end knife comes with better control, precision, and durability. They also tend to be safer because they are less likely to break while you are using force in the deboning process.
For some, an electric fillet knife is the quickest and easiest to use. The Waring Pro EK120 was voted the best electric fillet knife. It has a cordless operation and adjustable slicing guide to ensure consistent fillets.
An electric option will be heavier and larger to handle and operate, and it does not have the flexibility or precision a hand-held knife does. Whichever knife you choose, make sure you are comfortable with it before you go after a large deboning job.
