Purpose

Boning knives are specifically made to cut through the ligament, muscle, fat, and connective tissue and separate the meat from the bone.

These knives can be used interchangeably. But doing so would not produce the best results. Fish fillet knives can be used to remove fish flesh from bones. However, they only function with little fish bones. On the other hand, a boning knife can be used for filleting, but its hardness can probably be an obstruction. So, it would be best to get the specific one for a specific task. 

Blade Length and Weight

There are several lengths for both boning and fileting knives. Both kinds of knives are usually found in the 5- to the 8-inch size range.

While you are cutting larger fish, you need to use longer filet knives, but smaller fish will require shorter ones.

Even though they appear similar in size, fileting knives are designed and manufactured to make them lighter than boning knives. Compared to boning knives, filet knives typically have a thinner blade.

Blade Flexibility

A filet knife has more flexibility. The blade is designed to have an easy serving so that it may easily cut into fish and detach it from the skin. Its flexibility can offer you better cuts with a more delicate serving. 

On the other hand, boning knives are comparatively stiffer. In order to take out the flesh from bones, you must cut through the connective tissue with it, which they were created for.

You would have trouble if you tried to do that with a flexible filet knife. Besides, since the blade was not intended for such use, there remains a high risk of snapping. 

Blade Design

Despite the fact that both kinds of knives usually have a nice curve, when you pay better attention to them, you will find out the differences. Boning knives are more straight up to their sharpened tip; this sharpened tip performs an important task as it can pierce the meat without any effort. With boning knives, the curves are also less noticeable.

Fillet knives have a significantly more prominent upward curve that ends at the sharp tip. It is ideal for filleting fish because it is made for long, steady cuts, but it is less useful in other kitchen situations.

To Wrap Up

It’s important to have a boning knife and a filet knife if you have to do a lot of deboning and fileting. But understanding the difference between these two, a boning knife and a filet knife, is important for those who don’t frequently debone or filet.
