Buying Guide For Best Fillet Knife For Saltwater Fish

Picking up the right fillet knife is not a simple task and if you are a beginner, it would be tough for you. So I recommended reading the buying guide.

Fillet knives are also a part of the boning knife family, and It’s used for removing the meat from the bones quickly without damaging the meat.

Before buying any knife, it’s important to read the buying guide to get a complete understanding of it.


Whether you are looking for a fillet knife or other types of knife, the blade is the most important part of a knife and you have to look into it properly.

The blade must be strong enough so that it doesn’t break easily also it must be capable of precise cutting.

Since you are going to use it for cleaning salt-water fish, it’s important to look at the material of the blade, or else your blade won’t last long.

Before buying any knife you must check whether the blade is made from stainless or it has a chromium coating or else your blade won’t last long.

And your blade will require maintenance to keep the blade safe from rusting.


It’s important to check the weight of the blade because for filleting fish you have to use the blade for a long time, and you don’t want your hands to pain.

If your blade doesn’t have a proper weight balance, it will be tough to use for a long time.

There is no specific weight for a fillet knife, however, according to my research, it must weigh between 8 ounces. It’s a perfect weight for fillet knives.

Some of them prefer using a lightweight knife, but some of them like a heavy knife.

But according to me, lightweight knives are more comfortable to use than heavier ones.


When buying a fillet knife, the primary consideration is to check the sharpness of the blade. There is no point in having a dull knife as it’s of no use.

Most of the fillet knives are made with Rockwell hardness and have around 12 to 15 bevel degrees for better cutting.

Usually, fillet knives are more flexible so that you can easily maneuver them for filleting and slicing. Therefore, most fillet knives are thinner and are more sharpened than other knives.


The handles of a fillet knife must be excellent enough and must be nonslippery for better grip. It’s not just the seawater that makes the handle slippery but also the fish.

So it’s important to have a good handle with a nonslippery grip. The most common types of handles are the trigger handles for fillet knife because it provides a place to rest the index finger.

Also, it secures your hand. I don’t recommend getting a fillet knife with steel handles because they are more slippery and have less grip.

Wood and rubber are considered the best materials for knife making. Also, they are comfortable and provide more grip.

What size fish fillet knife is best?

As you know there are many sizes of fillet knives available and if you are a beginner, it would be tough for you to decide which one to go with.

Well, the correct answer depends on what fish you are mostly working with. The general rule to decide the size is your knife should be at least 2″ longer than the fish.

So that there is enough room to move the blade while slicing or else you will not cut it well.

There are many sizes of fillet knives ranging from 4 to 10 inches long. Usually, the shorter knives are between 4 to 6 inches. 

Short knives are mostly used for cutting small fish like perch, mackerel, or trout.

But if you are someone who is always working with big-size fish like tuna and codfish, then most probably I recommend using a 7 to 9-inch blade for more versatile and comfortable cutting.

Usually, the size of the fish will decide the length of the blade. So before getting your fillet knife it’s recommended to know which fish you are mostly going to work with.

What Makes a Good Fish Fillet Knife?

The buying guide will help you in deciding how to choose the right type of knife but it doesn’t mean you are getting the best quality knife.

There are some characteristics that a knife possesses that make a good fillet knife.


A fillet knife must be flexible enough so that it’s easy to cut through the blade spine and the bones.

If your knife isn’t flexible, you cannot make a clean cut. So before buying a fillet knife you always check the flexibility of the blade.

However, the blade must be so flexible that it breaks down easily.

Thin Blade 

Fillet knives should be thin yet durable. The blade must be thin enough so that it precisely cut through the skin and the flesh of the fish without even damaging the actual meat.

Also, the tinner blade makes the battle even more flexible, and it becomes easy to maneuver.

But your blade must be durable enough so that it doesn’t break or bend while cutting some hard bones and skin.

Light Weight 

A fishing fillet knife must be lightweight like lie a slicing knife for easy maneuverability through the contour of the fish.

The lightweight blade will help you work with large fish and work for a longer time. With a heavy knife, you have to unnecessarily put in extra effort.

Right Bevel

Your blade must at least have a 12 to 15-degree bevel for better cutting. This will help in cutting delicate fish like tuna and even salmon.
