Boning Knife vs Fillet Knife – What’s the Difference?

Wondering which knife is better between a boning knife vs a fillet knife? This brief guide can help you find out.

Many people tend to think of a boning knife and fillet knife as synonymous with one another. However, nothing could be further from the truth.

While they may somewhat resemble each other, a boning knife and fillet knife have distinctive designs and functions.

My guide below can help you make a clear distinction between the two and, ultimately, decide which one better serves your needs.

What Is a Boning Knife?

A boning knife is a long knife fitted with a narrow blade with a sharp point. As its name suggests, it is typically used to debone (remove flesh from bones) meat and poultry. Its narrow, thin, and sharp-pointed blade allows precision boning and deep cuts.

Its blade also features an arched edge for easy single-pass cuts through the flesh. Furthermore, the blade features a stiff build to prevent it from snapping even when cutting through tough meats.

What Is a Boning Knife Mostly Used For?

A boning knife is mainly used for removing flesh from the bones of meat and poultry. The knife cuts through ligaments, connective tissues, and fats to prepare meat for cooking. After deboning it, you can also use a boning knife to cut the meat.

Can a Boning Knife Be Used as a Fillet Knife?

A boning knife can sometimes be used as a fillet knife. When shopping for a boning knife, you will encounter an overlapping all-purpose model you may use as a filet knife.

These boning knives tend to have a flexible blade that handles delicate fish without tearing or damaging the flesh. Nonetheless, even the best all-purpose boning knife will not do nearly as good of a job as a true fillet knife.

A fillet knife is a kitchen knife fitted with a thin, sharp, and extremely flexible blade. The knife is built for deboning purposes, particularly removing bones from fish. Its thin and sharp blade also allows it to slice thin fish cuts.

What Is a Fillet Knife Mostly Used For?

Typically, a fillet knife is used for cutting fish and removing fish bones. Its flexible blade, as opposed to a stiff one, makes it perfect for tackling delicate fish. You will also find specially serrated fillet knives designed for bigger fish like tuna.

Can a Fillet Knife Be Used as a Boning Knife?

A fillet knife doesn’t handle the tasks of a boning knife well. So, in most cases, you cannot use a fillet knife as a boning knife. This is because a fillet knife is typically designed to handle delicate fish and requires a flexible blade.

On the other hand, a boning knife is designed for meats and poultry, which need a stiffer and harder blade. So, using a fillet knife for such meat can risk snapping the blade of a fillet knife.

Top 3 Fillet Knives You Should Check

Main Differences Between Boning Knife vs Fillet Knife

Boning knife and fillet knife differences
A boning knife and a fillet knife comes with several key differences. We’ve listed the most common differences to help you determine which knife is best for you.

Blade Design

Both boning and fillet knives have a thin blade design. However, boning knives tend to be a little thicker and stiffer than fillet knives. This allows them to tackle the much thicker flesh and bones of meat and poultry.

On the other hand, fillet knives are much thinner and more flexible, allowing them to perform delicate tasks.


Boning and fillet knives differ in blade lengths. Fillet knives can be found in 4 to 9-inch blades, depending on the fish to work on.

Shorter blades work for smaller fish, while longer ones are for large fish. Boning knives are fitted with 5 to 6-inch blades since they don’t require much precision for the less delicate meat and poultry.


A boning knife has a stiff blade which allows it to tackle the tougher and more demanding meat and poultry. A flexible blade on a boning knife would easily snap from the force used to handle the meat.

Fillet knives have more flexible blades, which allows better maneuverability. The flexibility of the blade prevents damaging and tearing the flesh of the fish.


Compared to other kitchen knives, a boning knife has a thin and narrow blade. However, compared to a fillet knife, it is much thicker.

The thickness allows it to handle the tougher meat and poultry, preventing it from snapping when in use. A fillet knife has an extremely thin and narrow blade which helps it handle delicate fish without tearing the flesh.

Curve or Straight

When it comes to the curvature, fillet knives have a curved blade while boning knives remain straight along the edge to the tip.

This sharp tip comes in handy for boning knives since it allows them to pierce through tough meat with ease. A filet knife has a pronounced upward curve and a curved tip. This blade design allows the knife to make long and consistent cuts.


Due to the difference in their design, each knife has a specialty task. A boning knife works great for removing bones from the flesh of meat and poultry.

It can also be used to cut the meat. A fillet knife is specially used to remove bones and skin from fish. You can also use the knife to cut and thinly slice the fish.

Boning Knife vs Fillet Knife – Which One Should You Buy?

The answer is pretty simple and obvious. There’s no better option than the other. Your choice of whether to get a boning or fillet knife entirely depends on how you intend to use them.

If you want a knife for deboning and cutting meat or poultry, you are better off with a boning knife. On the other hand, a fillet knife is handy for removing bones and skin from fish and cutting and thinly slicing it.
