How To Choose The Best Fish Fillet Knife

Selecting a good fillet knife is easy if you know what to look for.  The two most important components of the knife are the blade and the handle.  If you do not have the correct blade, the meat could be ruined during the filleting process.  Choose a knife with poor handle qualities and you could risk injury.


A good fillet knife will have a long, thin, flexible blade.  This provides the control and maneuverability necessary to remove bones, skin, entrails, and fins.

As I am sure you can imagine, the blade is the most important aspect of a fillet knife.  Always look for a blade that is thin but tough and holds a good sharp edge.  You also want to consider what the blade is made out of.  Stainless steel is the best option because it won’t rust or warp.


Choosing an ergonomic handle that fits comfortably in your hand is invariably the best way to go.  This will allow you to maintain blade control while also keeping a firm grip on the handle.  A comfortable handle also helps to reduce strain and fatigue.

It is also important to look for a fillet knife with a finger guard.  The finger guard is located on the handle where it meets the blade.  A finger guard further protects your hand from slipping off the handle and down the blade of the knife.

What Size Fish Fillet Knife Is Best?

Now that you know what to look for in a fillet knife, it is time to figure out what size to use.  The size of the fish you are filleting determines the length of the knife used. The general rule of thumb is that the knife should be at least 2″ longer than the fish you are filleting.  This will allow for enough space to move while you are slicing.

With this in mind, fillet knives are typically 4 to 10 inches long.  Shorter knives (4″-6″) are used for smaller fish, like perch and trout.  If you are reeling in a medium-sized fish, like a salmon or catfish, then a 7″-8″ blade is more appropriate.  For larger catches, such as halibut or tuna, a knife that is at least 8″ or larger works great.

Do You Need A Fillet Knife To Fillet A Fish?

The short answer to this question is yes.  Technically, you can still fillet a fish without a fillet knife.  However, without a specialized implement, you are sure to lose a lot of precious meat.

Any standard knife will have a thicker, more rigid blade.  Remember, a thin and flexible blade is crucial for getting the skin off of a fish.  Using a regular knife will get you enough meat to use as a stock, but not a fillet.

Fillet knives are built to fillet fish.  They are designed to move easily along the backbone and under the skin.  They offer control and precision while slicing around the contours of the fish without damaging the exquisite meat.
