What to look for in a Fillet Knife?

Buying the right fillet knife is not that much easy. Before selecting any one, you must have proper knowledge about the must-haves of a fillet knife. You have to look for a high-quality blade while purchasing the best filet knife. The fillet knife’s blade for cleaning fish must be thin but still durable and can hold a sharp edge. The length of the fish also matters a lot, which you are cleaning. The next thing which you should take into account is its material.

Usually, the fillet knives are made up of high-quality stainless steel material. But keep this thing in mind that all stainless steel materials are not of equal quality. Unfortunately, many fillet knives do not show the type of stainless steel, but at this time, you have to choose a reputable company. Another consideration is that the best fillet knife for fish can be used outdoors and in wet conditions.

There are many factors that you have to consider before purchasing the best fillet knife kitchen.

1.Japanese VS German

For the fillet knives, there are mainly two best options. First one is the German and the second is Japanese. Both of these differ in the sharpness, angle, edge, thickness, and hardness. But keep this point in your consideration that the lower the angle of the blade, the sharper the blade is.

You will find German knives with a wide blade angle near to 18 degrees. While on the other hand, the Japanese fillet knives are with the angles of 10 to 15 degrees. So you may get clear which to opt for.

But apart from the angles, there is something named design. And the majority of the people look for a better design. From both of the options, you will get German knives with thick bolsters. Thus the blade becomes capable of cutting through the meats and tough veggies fluently.

2. Full VS Partial Tang:

Having proper information about the type of tang is crucial. But wait, do you know what tang is? It is the metal part that includes both the blade and the remaining piece of blade that have extension through the whole handle.

A knife with full tang is one that has metal extending from the tip to the butt. While on the other side, the partial one is with partial tang. It means that the tang is not extended to the full length of the handle. The knives with full length tang are stronger because they don’t have any weak points plus they possess a better balance. So always opt for the knife that is with full length tang.

3. Size of the Blade:

The size of the knife blade usually ranges from a 4-inch fillet knife and 9 inches in length. Usually, top-rated fillet knives’ standard size is 4, 6, 7.5, and 9 inches. Although they come in different varieties, these varieties’ main reason is related to the size of the fish you are using for making fillets.

So if the fish size is more prominent, then the blade’s length is also significant, and if the fish size is smaller, you will use a small size blade knife.

4. Material of blade & Handle for fillet knife

When you purchase the fillet knife for cleaning fish, the knife’s material also plays a significant role. The handles were made up of wood in the past, but plastic and rubber took their place in the market.

Nowadays, manufacturers are not using wood as the fillet knife’s handle because it gets too slippery and difficult to handle when it is wet. So you do not have full control over the best fish fillet knife when the handle is of wood. The other drawback of wooden handles is that they absorb the smell of fish while you’re cutting it.

If we talk about the blade material, then it is made up of stainless steel. Stainless steel material is quite practical even if it’s frequently wet. For this purpose, chromium is made use in stainless steel blades, which makes them resistant to corrosion. The corrosion resistance prevents the staining of the blades. Therefore they are easy to use and clean.

5. Tip of the Fillet Knife:

Many fillet knives have a pointed blade, with the help of which the slicing and screening of the fish become easier. Usually, the back edge of the blade of the knife curves upward from the handle to the tip. This curve helps increase the knife belly’s size, which is the cutting edge’s curved part.

6. Thickness of Blade:

The thickness of the fish fillet knife and flex is usually associated with the point blade’s length. Suppose the size of the blade is smaller, then it is thinner and more flexible. The perfect fillet knife’s property has more flex, and if the flex is greater, it will work efficiently around bones.

It is also helpful in removing the skin of the fish. So if you are purchasing the best fillet knife for rockfish, it must be flexible enough to make good fillets. Usually, the best fish filet knife blades are skinny, approximately 2.5 to 3.5 millimeters at the spine. If the blade is stiff, it is difficult to remove the skin from the fillet or work around the rib bones.

When the skin of the fillet is removed, then the thinness of the blade is magnified. So, the amazing quality fillet knife’s blade must come with great flexibility when removing skin to follow the fish’s contours. These knives are from the boning knife family because they are very flexible and used to fillet and prepare fish.

Usually, the blade of a high-quality fillet knife is 15 to 28 cm or 6 to 11 inches, which allows them to move quickly while cutting fish. Moreover, you can also move the blade knife of the knife along the backbone and under the meat’s skin with ease.

7. Electric Fillet Knives

Along with the manual fillet knives, electric fillet knives are also available. They are modern ones and are suitable for those who want to clean the mess of fish regularly.

They are easy to use, and you can effortlessly work to make the fillets and cut them. Along with its easy-to-use function, it also saves you a lot of time when you do not have to put a lot of effort into cutting a fish. Keep in mind that it is not easy to use the electric top-quality fillet knife because it is electric and has a bit of a learning curve. So you will take some time to get used to it.

Uses of the best fillet knife

The fish fillet knife is also called a filleting knife, usually used in the kitchen to cut meat, especially fish. It is beneficial in making good fillets and gives you reasonable control in doing all the things.
