Buying Guide of the Best Fillet Knife for Saltwater Fish

For filleting saltwater fish, there is a common problem that most people don’t realize they are making. The most common problem when filleting saltwater fish is finding the right knife. Unlike their freshwater counterparts, saltwater fish often require a knife that is thin, sharp, and short.

To pick up the best fillet knife for saltwater fish, you need to consider some important factors. This includes-


One of the first features of a knife in a saltwater fish fillet is that its blades must be corrosion resistant. Knife blades made using high-quality steel are usually rust-resistant.

The blades of the fillet knives need to be slightly curved. Curve blades can cut precisely and play a role in maximizing the amount of flesh from the bone because of the detailed cutting.

An actual fillet knife blade must have sufficient flex. This makes filleting easier. Flexible blades will easily follow the shape of a fish for filleting compared to relatively strong blades.


Saltwater fish, especially large fish, usually prefer a slightly larger size blade. Here, 7 to 9-inch blades are more effective. Blades of this size allow you to get things done faster.

Usually, the fillet knife blades are very thin. The thickness of the blade of the fillet knife is about 2.5 to 3.5 mm for easy bending or flexing. The blades of this thickness can be sharpened easily and are simple to maintain edges. 


The blades of most fillet knives are quite flexible and its bevel is about 12-17 degrees, which allows for sharpness. However, it reduces the durability of the Edge.

An edge bevel of 12 to 15 degrees on each side provides a clean, easy cut, and reasonable resistance to dullness. A 15-degree bevel will serve you well if you don’t cut the bone, or the bait, with your fillet knife.

The edge of the knife should be slightly duller than the razor blade. You need to use your skills to make up for the lack of sharpness. But if you have less skill, you will mash the fish more than a piece.


The handle of a knife plays the most important role in working perfectly and comfortably. Improved grip eliminates wrist numbness and allows you to work longer hours.

Things like fish filleting are usually done in a wet or oily environment. So the handle must be non-slip. Here, high-quality plastic or rubber grips are most convenient.


Need to have a good quality sheath with the knife. This ensures the safety of both the knife and the user.

A standard sheath protects the sharp edge of the knife and does not allow the knife to be damaged during transport. Having a belt loop with most sheaths makes knives much easier to carry. In addition, sheaths play a role in protecting the user from accidental damage.


Saltwater is a harsh environment, and the knives used here decompose relatively quickly. So when choosing the best fillet knife for saltwater fish, you must consider the cost. As well as the warranty can give you a great deal of assurance about your investment.


Q. What is the perfect size for a saltwater fish filleting knife?

A. A 6-inch knife is usually considered perfect for fish filleting. However, for saltwater fish or slightly larger-sized fish, everyone prefers 7 to 9-inch size knives. Because these are relatively more convenient and work can be done faster.

Q. What are the characteristics of a good quality fillet knife?

A. Material – Must be made of rust-resistant material, in which case good quality stainless steels are ideal.

Blade size – Curved blades play a key role in effectively removing flesh from the bones.

Flexibility – Blades need to be flexible, which makes the filtration process easier.

Handle- Handles with non-slip and comfortable grip are more suitable, as most of the time you may have to work in a wet and oily environment.

Sharpness- Although the blades are not like razors, must be sharp enough.

Q. Should fillet knives be serrated?

A. The thicker scale makes it harder to start a fillet as well as dulls the knife faster. For filleting a large stripper, you can apply a serrated fillet knife to slice and cut through the skin. Next, finish the task with a 9-inch fillet knife. Serrated knives are also standard for cutting frozen bait.

Q. Are boning knives the same as filleting knives?

A. Boning knives are used for preparing poultry and other meat products while filleting knives are used for filleting fish, meat, and other tough foods. They’re both very similar, but many chefs prefer one over the other. Filleting knives are typically longer, thinner, and more flexible than boning knives.

Q. How many types of fillet knives are available?

A. There are basically two types of fillet knives available: manual or electric. Both knives work almost identically. However, even the best electric fillet knife for saltwater fish can be larger, heavier, and more expensive too.
