A fillet knife can be one of the most overlooked knives in your set. Most people will just revert to using a chef knife for all their filleting needs, but in all reality, owning the best fillet knife will help you so much more than a chef knife.
A fillet knife is specifically designed to give you the lightweight handling and control you desire when cleaning fish. The blade tends to be very flexible yet durable to ensure that the meat separates from the bone and skin easily.
In this article, we will review several top-quality fillet knives to determine which is the best choice for you. We will also go over some things to look at when choosing a fillet knife so that you can make the right decision.
How to Choose a Fillet Knife
Choosing the best fillet knife is just like choosing any other knife. You want a knife to exceed all expectations and most importantly, last a lifetime.
Several different factors to consider are blade sharpness, blade retention, and overall construction. You will, of course, want to find the best quality of materials to create a quality knife. But you will also want some kind of warranty to guarantee the longevity of your fillet knife.
Blade retention and sharpness
The sharpness of the blade will play a major role in your ability to make precise and accurate cuts when filleting a fish. Having the absolute sharpest edge on your fillet knife is key. If your edge is not sharp then you may tear at the flesh of the meat, leaving the meat unseparated from the skin and bone, which you do not want.
Blade retention is the ability of the knife to hold a sharp edge over time. Of course, you can use a sharpening stone or sharpening steel to sharpen your knife. But most knives are constructed of higher carbon metals, allowing them to remain extremely sharp over time without needing to sharpen them.
The quality of the materials used to create the knife will determine if the blade will do what you want it to do. For a fillet knife, you want the blade to be thin, flexible and strong.
Most Japanese knives are made with a higher carbon metal, making them thinner and sharper. Fillet knives are also constructed to bend without breaking, so a thinner metal will help to add flexibility.
Other things to look for in a fillet knife would be the handle construction. You will want a knife with a full tang and at least 3 rivets within the handle. This will make the knife stronger.
A handle that has an agronomical shape helps when handling the knife. You will want the knife to be lightweight but also have a good feel when held in your hand.
The type of knife or what they call they blade will not matter as much. For instance, some may call their fillet knife a boning knife, when in all reality this is the same as a fillet knife. However, some may call their fillet knife a carving knife. This is not the same as a fillet knife. So, make sure what you are purchasing is indeed a fillet knife.
Price Point and Guarantees
Purchasing a quality knife can become quite expensive. So, make sure that when you are choosing the best fillet knife, the knife comes with some sort of warranty.
Even though most fillet knives are durable and flexible, they are also the most prone to break or have some chipping over time. A warranty will help to protect your knife when it breaks. Most quality knife makers offer a lifetime warranty with their knives because they are confident it will last forever. If it doesn’t, they will either fix the knife for you or replace it completely.
Care and Upkeep
General care for your knife is not complicated. Always handle the knife with care as to not drop it. Store the knife in a wooden block or in a cool and dry area.
When cleaning the knife, do not place it in the dishwasher or leave it to soak in water. This will damage the edge of the blade and in some cases the handle as well.
To clean your knife, hand wash under warm water with soap. Dry the knife immediately with a towel, do not let the knife air dry.
