Things To Consider Before Buying A Perfect Fillet Knife for Saltwater Fish

Before straightway jumping on to the best fillet knife for saltwater fish, let us first understand what makes a great fillet knife and what things you should consider to make the right fillet knife purchasing decision.

Fillet knife blade

What sets an exemplary saltwater fillet knife apart from an ordinary fillet knife is primarily its ‘blade.’ The knife blade makes all the difference! Before purchasing, ensure that the knife blade is flexible, lightweight, sharp, and made of perfectly coated, stainless steel, enabling you to clean, cut, and fillet fish without any hassles. When scrutinizing the blade, a few parameters to consider are

Blade length

The saltwater fillet knife blade is available in diverse sizes or lengths. Ranging from 5 inches to 9-10 inches, you can find a spectrum of knives to fulfill all your fillet needs.  The shorter blades work well for smaller species of fishes majorly, including yellow perch, crappies, and sunfish. Medium-sized blades ranging from 6-8 inches are ideal for eater-sized fishes like trout, while longer blades are most suited for bigger saltwater fishes.

Flex and thickness

You must be wondering, does the thickness and flex of the blade matter? Well, absolutely! The knife’s performance can largely depend on the thickness of the blade. A thin and flexible blade can smoothly glide all around the bones of the fish, while with a thick blade, it will be hard to get clean cuts, and you will have to put on greater pressure. Stiff & thick blades are most suited for deboning & cutting fillets to serving, while flexible & thin/medium blades are versatile & used for all purposes.


While buying a fillet knife, you would want a quality knife that will last you a long time, isn’t it? Well, this requires you to carefully select a knife that promises high durability and has a corrosion & rust prevention nature. As saltwater can easily corrode knives, make sure you don’t fail to notice this factor. Along with checking manufacturers’ warranty, choosing a knife with high-carbon German steel or titanium nitride coating is a wise decision as it ensures the long life of your knife.

Full Tang

A full tang knife’s blade has solid steel that runs throughout the knife’s handle. When looking for a perfect fillet knife, make sure to go with a full tang knife to save yourself from wrist fatigue. Knives with partial tangs may not last for long. Full tang construction may, however, increase the weight of your tool but can highly enhance its feel and balance. A full tang knife also ensures better strength, stability, and control.

Handle and Grip

Often overlooked, the knife handle must be carefully looked into. As you have some big fish to fillet, your knife must be able to provide you with a comfortable and smooth grip. Most importantly, it should be non-slippery to avoid any accidental cuts while you are working with it. Even while you are working in wet weather with blood and water all through your hands, your knife handle must provide you with a strong grip without failing. Fillet knife handles may come in a vast array of materials, like wood, rubber, and plastic, it is recommended that you go with a non-slip soft grip rubber.

Portability & sheath

If you are a beginner or an angular who travels a lot to gather fish, choosing a lightweight and portable knife is well suited to your needs. On the other hand, if you are looking for a knife for boat or home use, you can go with bigger knives or even electric knives. However, if you need to carry your knife all around, make sure that you choose a knife that comes with a sheath along with the belt. A sheath with open slots is perfect to keep your knife dry and functional for a long time.


You won’t have you spend a fortune getting a saltwater fillet knife. There are many saltwater knives available online that are decently and fairly priced without compromising on the knife quality. All you need to do is research, compare features, compare different prices, and find your ideal piece of a knife. However, if you intend to go with an electric knife, it may cost a bit higher, but will offer great value for money.
