Filleting is no easy work, especially with a regular knife.

Chopping up meat is hard enough, but at least it has visible bones and gunk you need to avoid, with fish, it’s all in one place, and you need a very sharp eye to figure out what exactly is going on and how you’re supposed to deal with it. This is precisely why you need a fish fillet knife.

A fish fillet knife is slightly different from regular ones because they have what you need to cut up a fish perfectly. The slightly pointed tip and the flexibility let you descale and follow the contours of the shish perfectly and lets you cut up and around the bones and spines without any extra waste or damage.

All you need is to cut, and the knife handles the rest. Now the question arises, where and what knife should you buy? Well, we’ve got you covered. This article has the seven best fillet knives for fish, their features, advantages, disadvantages, and a complete buyers’ guide so that you can decide what you want hassle-free.

If a stylish knife is your priority, then this is the knife for you.

The six-inch blade is harder, more stringent, and considerably more resistant to corrosion than other blades.

It is also versatile enough to be used on all types and sizes of fish. It lets you make clean, precise cuts, and the curve lets you cut along the contours of the fish.

The vented design lets air pass in and out, drying the water easily and quickly. While the price is roughly 25 dollars, it is way too costly for something that doesn’t set it apart from the crowd.

Overall, it’s a good knife to have, but it isn’t something you’d spend more than ten dollars on. Maybe it’ll last a year or more, but quality-wise, the knife is quite painfully average.

Features

The Lightweight, plastic sheath is excellent for this knife in particular since the vents will let air dry any remaining moisture on the blade and prevent corrosion, making it the perfect knife to use on the go.

How to Pick the Best Fillet Knife for Fishing? – A Detailed Buyers’ Guide

We’ve already established that getting a fillet knife for yourself can be pretty tricky. Now, after perusing through our recommendations, you’re probably wondering which one to get. Well, not to worry, because we have you covered. Below, you’ll find some of the most critical factors you need to consider when getting your fish filleting knife.

Blade

This may seem like a no-brainer, but you need to look into a lot when choosing a blade, especially for a fillet knife. First off, is your blade strong enough? Can it withhold specific pressures and tough meats? If the answer is yes, you’re on the right track.

However, it is essential to remember that toughness and sharpness go hand in hand. If your blade is tough and hard, it should also be sharp enough to not dull after a few months. Constantly sharpening a blade is a pain that you’d rather not go through on a bi-monthly basis. Another thing to consider is whether your blade has a sharp tip. Fishes need thin, delicate cuts, and you can’t do that with the whole length of the blade. You need to make sure the blade has a sharp tip and a slight curve so that it lets you make thinner cuts.

Finally, the last thing you need to consider in a blade is flexibility. If your blade is not flexible, don’t get it. You need a flexible blade to be able to make cuts along with the contours of the fish itself. If the blade doesn’t let you do that, you’ll be having some difficulties, to say the least.

Handle

Some things to look for in a handle is the material, is it non-slip, is it high friction, and is it resistant to weather and wear? For any handle to be a good handle, it has to be made of good material. Usually, rubber and hard plastic is the way to go, since they have a firm grip, don’t hurt your hands and don’t add any extra weight which makes maneuvering difficult. However, you also need to consider whether it will last long enough.

For that, you need to look out for its resistance towards certain elements. For example, will it deteriorate in certain weather conditions? Will it become too slippery to hold if the handle is wet? Does the material come apart if i pick at it/ or have high friction against it? If the answer is yes to any of those questions, you need to choose another knife.

Accessories: Sheath and/or Sharpener

If your knife doesn’t come with a sheath, it isn’t worth whatever you’re paying for it. Having a sheath is the most important thing you need if you have a knife. It keeps the blade from dulling and keeps it sharp and hard, it is also essential for safety, especially if you have family around.

These knives are very sharp, and you need protection. Now, you don’t get a lot of say in this but try to get a sheath made of rubber, especially if it is vented. It is generally safer, and the vents keep the blade from corroding since the airflow dries any moisture on the blade and doesn’t let it build. As for any other accessories like belt loops, sharpeners, those are purely optional, but definitely handy to have around, especially if you’re a professional.

Conclusion

With that, we come to an end of the best fillet knives for fish in 2020. We hope you enjoyed reading this and found something useful in it. What’s your favorite knife?
