Fillet Knives 101

A fillet knife typically has a 4 to 9 inch flexible blade that gives good control when filleting a fish. The knife has several distinct characteristics, which we discuss below.

Blade

The most popular material for fillet knife blades is stainless steel. Chromium is often added to the stainless steel blades to prevent corrosion since fillet knives are frequently wet. Adding chromium to the blade also helps prevent the pitting corrosion that can occur when you use a knife to cut raw meat.

The thickness of the blade is also important. A fillet knife needs to be flexible to remove the skin from the fish and cut around the bones. The best way to do this is to have a thin blade, so it can keep a sharp edge and still be flexible.

Fillet knives also have a longer bevel than most other types of knives. This gives filet knives an extremely sharp edge as well as a sharp point. This allows the fillet knife to cut around the bones without cutting into them.

Handle

Fillet knives generally have rubber or plastic handles to allow them to hold up under the continually wet conditions they are exposed to. The handle is usually shaped like a teardrop to give the user a place to put their index finger so it doesn’t get cut.

What Is the Difference Between a Boning Knife and a Fillet Knife?

People typically use boning knives to remove the bones from meat. Whereas fillet knives are generally used to remove the skin and bones from fish, although they can be used to remove the bones from meat as well.

These knives are sometimes used interchangeably, but a fillet knife is better when skinning and deboning fish. It is thinner and more flexible than a boning knife, which makes it better for the meticulous work involved in preparing fish for cooking.

How to Choose the Best Fillet Knife for the Job

Although you could use almost any knife to prepare your fish, not all knives will do the job safely and efficiently. A fillet knife can make quick work of deboning and skinning your fish. However, not all fillet knives do the job equally well. So, we are going to give some suggestions for what to look for in a fillet knife.

The most important feature to consider in a fillet knife is the blade. The best fillet knives are thin, flexible, and very sharp. You’ll also want your knife to hold up well to salt water. Blades made of stainless steel work well for this. The best length really depends on the fish you are cutting. Smaller blades work better on small species of fish. Whereas you may need a longer blade to efficiently cut larger fish.

A good handle needs to be comfortable and safe. If you’re cleaning a big batch of fish, you don’t want to be halfway through and find your hand is sore and tired. So, choose an ergonomically designed handle with a good grip that will ensure you’re safe and comfortable.

Don’t forget the sheath while picking your fillet knife. Although it may not be the biggest factor when choosing your knife, it is what keeps you safe when transporting it. You’ll want a sheath that allows adequate draining to keep your knife in good condition. Also, some sheaths provide nice extras, such as built-in blade sharpeners or belt loops.

What Makes a Good Filleting Knife?

A good fillet knife will allow you to comfortably clean your fish without wasting much of the fish. No one wants to spend the day fishing only to have a lot of their catch end up in the garbage. But, with the right knife, this won’t happen.

A quality fillet knife will have a long thin, flexible blade to allow for delicate cuts around the bones. A dull blade can tear the flesh and break the bones wasting fish and leaving bones in your dinner. You’ll want the blade to be made from high-carbon stainless steel, which will help the knife stay sharper longer and resist rust.

A good knife isn’t really worth the money if it’s not comfortable to use. So, choose your handle carefully. Pick a knife with an ergonomic handle and a non-slip surface. After all, deboning and skinning fish is slippery work, and you don’t want to lose any fingers.
