Buyer’s Guide for Fillet Knives

Filleting fish is more than a job you have to perform. It’s also an art form. You need a blade that’s going to give you laser precision. As you may have already guessed, not just any fillet knife will do.

You need one with quality craftsmanship. It has to be durable. A little bit of flex doesn’t hurt, either. To make sure you choose the right knife, let’s cover some of the basics. You’ll soon be on your way to buying the best fillet knife for your needs.

How to Choose the Right Fillet Knife

There are five main components that go into crafting the perfect knife. They are size, angle, handle, flex, and material. Let’s go over them one at a time.

Size

Fillet knife blades typically come in four different lengths: 4, 6, 7.5, and 9 inches. This is so you can pick the right blade for the job. If you’re filleting a large fish, you’ll want a longer blade. Pretty simple reasoning, right?

Angle

Knives come with all different degrees of angles. The angle depends largely on the type of knife. Razors and the like usually see an angle of 7° to 12°. Kitchen knives run between 17° to 25°. Fillet knives are in the middle, usually around 12° to 17°.

Angle degrees are simply a matter of preference. Depending on your cutlery level of expertise, you may not even notice any difference. Play around with different angles, you may find that you get better results out of different ones.

Handle

Blade sizes and angles are important. But having a handle that you’re comfortable with can make all the difference in performance and how well you operate the knife.

You want to make sure that the material used is one that will suit you. Do you like to have a ridgy, rubbery grip? Maybe you prefer an all-wood feel. Some people like to have a combination of metal and wood. As you can see, this again comes down to personal preference.

Wood can be soft, yet firm. It’s warmer to the touch than metal and gives the knife a classic look. Rubber generally provides a nice, tight grip. But there are other differences that come into play.

Wood tends to retain fishy odors. It soaks in smells much more so than any other material. It also gets slick from oils and moisture. Rubber, on the other hand, doesn’t do any of that. It’s easier to clean and lasts a lot longer, too.

Flex

Having the right amount of flex can make filleting much easier. The blade moves around bones better, and with the right amount of practice, this becomes an art form.

There are some who have an easier time with a sturdier place, however. They find that flex makes it difficult to cut away meat from the bone. It all gets down to your style of filleting.

Once again, it’s all preference. Some knives flex more or less than others. You may not like a lot of flex if you’re new to filleting. But the more you do it, you may find that you actually prefer it. Read reviews – ours included – to see which knives flex and which ones don’t.

Material

This may be the most important aspect of all. Many knives are made of stainless steel. But how well they’re made and the process used in refining the blade has a big impact on the end result. If there isn’t quality research going into getting a durable blade, chances are it will fail on you sooner rather than later.

Carefully read each review to learn what kind of metal the manufacturer used. Some make better blades than others. If they’re refined properly, you can end up with a blade that lasts a lifetime.
