Why Can You Trust Us?

As an avid angler and gear junkie, I have quite a collection of fishing knives of all shapes and sizes. For instance, I have used various blade types, and I’ve wielded knives with non-slip grips or wooden handles. I have even experienced the misfortune of buying both electric and non-electric fillet knives that weren’t worth their price tag.

Thus, I want to share with you what features are essential to get the most out of your purchase. Now, let’s get started by looking at our favorite saltwater fishing knife.

Best Fillet Knife for Saltwater Fish

Second, the grip on this knife is insane! For instance, the handle is comfortable, has a lot of traction, and the trigger grip feels natural in your hand. Plus, you can make some pretty precise cuts with this blade.

Also, we like the various size options of the Controller, so you could virtually use it to fillet any species. In addition, this knife is both cosmetically pleasing, and it looks like it can withstand some abuse.

Features To Look For In a Fillet Knife

Now, let’s examine what features to pay attention to before purchasing a new fillet fishing knife.

Flexible Blade

First, you want to ensure it has a flexible blade. Flexibility is critical for precise cutting, and it’ll help you work around the bones of the fish effortlessly. Beware, some boning knives get marketed as fillet knives; however, these blades are heavier and more rigid. Also, a boning knife is better for cutting through tough skin, ligaments and removing meat from heavy bones.

Blade Material

Next, you want to examine the blade material and size of your fish fillet knife. The most common materials you’ll likely see on the market are stainless steel and carbon steel. Here is a quick reference of how these two differ:

  • Stainless Steel: is the most common material, and it’s affordable, durable, easy to sharpen, and corrosive resistant. Consequently, making it more superior for saltwater use.
  • Carbon Steel: is stronger and more expensive than stainless steel; however, it is more likely to corrode. In comparison, carbon steel is a quality blade that’s easy to sharpen, and it’ll hold a sharp edge longer.

Blade Size

Now that you understand the importance of a blade’s material let’s discuss its size. First, there isn’t a one-size-fits-all length; however, a 7 ½-inch blade is an excellent middle ground. Even so, the best way to pick what length blade to purchase is to match it with the type of fish you’ll catch. Thus, the rule of thumb is you want the length of the blade to cover the width of the fish you’re filleting.

Grip Handle Material and Shape

Most importantly, regardless of what handle material you end up choosing, you want to ensure it has a non-slip grip. Consequently, using a knife without a non-slip grip could lead to injury since the blade could shift more easily. Furthermore, the shape of the handle should be comfortable in your hand. For example, having a knife with a bulk decorative handle could likely hinder your precision.

Electric Knives Versus Non-Electric

Now, let’s compare electric knives to traditional ones. The main reasons most anglers don’t like electric knives are:

  • You need to charge them or plug them in every use
  • Some overheat after continuous use
  • They believe electric knives aren’t as accurate
  • They may require more maintenance
  • Electric fillet knives can be more expensive

However, there are also some pluses to using an electric fillet knife like:

  • They’re powerful
  • They require less effort
  • You can fillet a larger quantity of fish quicker
  • It’s easier to cut into tough fish or scales

Therefore, there are both drawbacks and benefits to using an electric fillet knife over a traditional one. Ultimately, only you can decide which one would better suit your needs and lifestyle.

Single-Piece Versus Folding

Then, many anglers also have difficulty deciding between buying a single-piece blade over a folding one. The most significant advantage of a folding fillet knife is they’re compact and easy to store. Plus, some anglers believe they’re safer to transport since the blade isn’t exposed.

However, despite these benefits of a folding blade, many anglers still prefer a single piece. For instance, most believe single-piece knives are overall more durable and outperform folding ones.

Serrated Edge Versus Plain Edge

Lastly, it would help if you decided whether or not you should use a serrated blade over a plain edge. The main benefits of serrated blades are:

  • They require less sharpening
  • You can cut through scales and tough skin easier
  • They are more durable than a plain edge.

Yet, there are also drawbacks to using a serrated blade like:

  • You need to buy a special sharpener for it
  • They don’t cut as clean as a plain edge
  • It’s not very versatile
