Things to Consider

Filleting a fresh caught Kokanee Salmon

There are several things you must keep in mind when you are looking for an electric fillet knife to buy. Let’s look at what some of these are in some detail.

Blade Material

The material of the blade of electric fillet knives is one of the most important things to look at. Usually, the blades of such knives are made from stainless steel that allows you to use it in saltwater as well.

The stainless steel should also be of excellent quality so that it can withstand all kinds and sizes of fish, allowing you to easily cut through them without exerting too much effort.

The quality of the stainless steel is also important to prevent rusting or corrosion on the blade as this could otherwise lead to poorer performance of the blade.


The electric fillet knife that you opt for should be sturdy and durable instead of too flimsy. This can be determined by the quality of the materials used to make the knife.

Since these knives have to deal with salt water and all kinds of fish, they should be strong enough and resistant to corrosion to a considerable extent. Further, the motor should also be able to withstand the power supply without heating up too much.

Usually, manufacturers tend to offer a limited warranty of one or two years that can give you an idea about their quality and durability. Make sure you look into the warranty policies of each knife so that you can ask for replacements without any hassle.


There should be sufficient safety features across the length of the knife to ensure that you can keep yourself protected while using the knife to fillet fish.

The first element of this is the grip of the handle. It must be strong enough with the kind of quality that lets you place your hand on it firmly without causing slippage. This is a necessary aspect for your knife, the absence of which could lead to minor or major injuries.

Author Note: The handle should also have a trigger that lets you turn the knife on or off whenever you need to. This can let you maintain your hold while also having some kind of control over the working of the knife.


The power that the electric knife can work on is also important here. Usually, the power cords that are attached to these knives can be connected to electrical sockets for delivering the current.

The output that they can deliver can help determine how the motor will function. Usually, 110 volts is considered to be a good enough voltage for these knives. It is essential to look into this detail before you make your decision.

The motor should also be able to handle the power well enough without causing overheating as this could reduce the efficiency of the knife.


It is essential to regularly clean and maintain your electric fillet knife. In fact, after each use, you must clean up the blade to prevent a build-up of bacteria and food remains.

Usually, these electric fillet knives come with removable blades that you can detach from the handle and clean up without letting water come into contact with the handle, motor, and cord.

Multiple blades can also help in this regard as you can easily replace one with the other. Some blades can also conveniently be cleaned in the dishwasher.


The speed at which the motor powers up the blade to fillet the fish is important to consider. Usually, this speed is constant in electric knives, but you can maintain control to a certain extent over the speed by pressing and releasing the trigger on the handle.

This can help you halt the process if you need to take a break or figure out how to deal with a tough section.

Some knives may also come with adjustable speed settings that allow you to set a certain speed of functioning. This gives a lot more flexibility and control over the process, but this is also a relatively rare feature.

Corded vs Cordless

Electric fillet knives can come with cords attached to them or they can be cordless. Cordless knives usually need frequent charging each time they run out of power, which is why all the knives we included in our reviews have a cord.

Corded knives can make it simpler since they can provide a constant amount of power as they need to be connected to a socket each time you want to use them. The power that they supply is also a bit stronger as compared to cordless knives.

On the other hand, it can certainly be easier to manage and carry cordless knives.

Author Note: Make sure you consider the length of the cord as well before buying a knife. Short lengths might be difficult to maneuver around easily and may need too many adjustments on your part.
