Difference Between Fillet Knife vs. Boning Knife

A fillet knife and a boning knife pretty much have a similar task. However, the details of their tasks and design slightly vary. A fillet knife is ideally designed to remove the skin and bones of fish.

These knives typically have a flexible, ultra-sharp, and long blade. Additionally, filleting knives are usually thin with blade lengths of around 5 to 9 inches.

Furthermore, the blade integrates an upward curve with a sharp curved tip. This ultra-thin and sharp design make it easier to trail through the body of the delicate fish.

This design also allows a fillet knife to easily remove fish scales while contouring the body without damaging the fish fillet.

On the other hand, a boning knife is designed for removing bones from the flesh of meat or poultry. Typically, a boning knife has a narrow, flat, and semi-stiff blade with a sharp point. However, the blade also has a straight and slightly curved tip.

Additionally, the blade length for boning knives falls around 5 to 7 inches. This design makes it easier to cut through ligaments and connective tissues, to easily remove meat from heavy bones without tearing it.

Furthermore, to deal with the thicker and heavier bones from different animal meat, boning knives tend to be thicker and stiffer than fillet knives.

Things You Need to Know Before Buying

best knife for filleting fish
Different people have different needs when it comes to picking kitchen equipment, including fish filleting knives.

Therefore, before choosing the best fish fillet knife, you need to know which features to look for to pick the right option. Here are the common features to examine when choosing a suitable filleting knife for fish.

Blade Materials

A good quality filet knife should be made from carbon steel or stainless steel. These materials stand out for their sharpness and edge retention along with their corrosion resistance.

However, stainless steel may be a little difficult to sharpen, although it retains sharpness for longer. On the other hand, carbon steel knives are better for people who want a lighter option.

Handle Materials and Comfort

Most fillet knife handles are made from wood, rubber, or plastic. While both materials offer great performance, each has its selling point and drawback.

Rubber offers a high grip even in wet conditions. On the other hand, wooden handles provide great aesthetics and durability. However, they get quite slippery in wet conditions.


When it comes to fish filleting knives, flexibility is an important feature. This is because every part of the task incorporates the need for a flexible blade.

This makes it easier to get closer to the bones to remove flesh and even thin skin without tearing the meat.

In this case, when choosing the right knife, go for one with a longer and thinner blade to achieve optimal flexibility.

Furthermore, a longer and thinner blade helps mitigate the risk of hand fatigue and pain. However, if you plan on using the knife for smaller fish, you are better off with a medium to shorter blade.

Size and Weight

Kitchen knives will come in different blade sizes. However, for a filleting fish knife, you want to go for a certain size range. Of course, the blade size choice depends on the type of fish you plan on working on.

If you typically plan on filleting small fish, a 4-inch to 6-inch blade is ideal. However, for bigger fish, you want to go for a 9-inch blade.

Nonetheless, many people opt for a compromise between small and big fish. Thus, you will find most fillet knives with 6-inch to 8-inch blades.

Advanced Safety Features

The safety your knife offers is crucial, especially when dealing with tricky tasks like filleting fish. So, when choosing the suitable knife option, make sure it offers ideal safety features.

Among the key features, you want to look out for is a safety bolster or finger guard to protect your fingers from cutting accidents. You also want to make sure the knife handle offers adequate grip.

Full vs. Partial Tang

When choosing a knife, you will have the choice between full and partial tang. A full tang means that the blade is fully attached to the handle.

This design gives the knife added durability and balance. It also prevents the blade from snapping from the handle. However, it makes the knife a little heavy.

On the other hand, a partial tang means that the blade is partially attached to the handle. While this design isn’t very durable, it makes the knife significantly lighter. Thus, it is an ideal option for beginners.

However, due to the risk of snapping, it is advised against using a partial tang knife for bigger fish that require more work and strength.

Price Range

The price for fillet knives for fish varies. It all depends on the features you are looking for and the knife’s quality. Generally, you should expect to pay anywhere between $20 on the low end and $200 on the high end.

Cleaning Ease

When shopping for fillet knives, you will find dishwasher-safe and hand-wash-only options. No doubt, dishwashing your kitchen items enhance convenience.

However, you are advised to hand wash your knife, even if it’s advertised as being dishwasher safe. This is because frequently washing your knife in the washer will ultimately compromise the blade quality and increase the risks of corrosion and rust.

Wrapping Up

With a good-quality fish fillet knife, you can truly improve the taste and look of your food. After all, as the saying goes, you first eat with your eyes!

So, the next time you want to host friends over for sushi or a nice salmon dinner, a fish filleting knife is an essential tool to have.

To help you prep accordingly, check out any of the 7 best fish fillet knife options above to pick a model that fits your needs!

Frequently Asked Questions

What type of knife is best for filleting fish?

In my long years of cooking experience, I can tell you that the most effective knife for filleting fish must have a sharp blade, durability to withstand repeated use, and the flexibility to bend without losing its accuracy. The grip is also a crucial factor since it needs to remain firm when dealing with the most slippery fish. The knife that has all these features is the Wusthof’s 7-inch fish fillet knife. Crafted by a company with over two centuries of knife-making experience, this tool will make the chore of filleting feel like a breeze.

What is the best size fillet knife for all around?

Over the years, I’ve noted that having a set of two to three fillet knives of different lengths can be helpful in dealing with varying filleting situations. However, if you want a one-size-fits-all solution, either because it’s your first purchase or you are limited on packing space for a trip, I’d recommend a fillet knife that’s 7 inches long. This size is a sweet spot that is not too long to handle smaller fish but also not too short to fillet the big ones.

What’s the best fillet knife for salmon?

Salmon is unique because of its size and its rich, fatty flesh that can be easily damaged if not handled correctly. After some trials and errors, I’ve found that the BUBBA 9” Stiff Fillet knife is perfect for tasks like cutting off a salmon’s head or dividing it into steaks. The blade is 2 mm thick, composed of titanium-nitride-coated high-carbon stainless steel that can deftly handle the robust nature of the larger, more abundant salmon.

What is the best budget fillet knife?

If you are on a tight budget and yet want a knife that does the job well, then don’t hesitate to go for the Rapala Fish ‘n Fillet. It has a wax-finished birch handle that provides comfortable gripping, and a flexible 6-inch stainless steel blade that seems made to fillet fish. The knife also comes with a bonus – a leather stealth to safegaurd your knife and a SH1 pull through sharpener to ensure the blade always remains sharp. It’s an excellent value-for-money purchase if you ask me.
