What is A Boning Knife?

Boning knives originated in chicken restaurants and were used to break down entire chickens. Nowadays, they are mainly used to separate meat and fish to obtain a boneless piece. The shape has been designed to be a flat edge with a straight and slight curve to it. It is usually found to be between 5 to 7 inches long and allows for precision cutting. Although it may not be able to handle immense pressure like a Santoku or Chef’s knife because of the thin blade, it sure does cut through ligaments and/or connective tissues which helps remove meat from big and small bones alike. However, boning knives are naturally thicker and stiffer than fillet knives.

What is A Fillet Knife?

A fillet knife is a thin blade that is also flexible. It is more common for a fillet knife to be more precise and delicate as it is used to cut up pieces of meats that are usually fragile. These blades are the ideal knives for fish as they are the perfect thinness and shape that allows for them to be a powerhouse in chopping up fish. These knives tend to be from anywhere between 5 to 9 inches. They have more of an upward curve leading up to the top and are sharpened at a 15 to 20-degree angle. These knives are delicate so make sure to treat them as such and only use them for removing scales from a fish while also flexing around the contours of its body. This knife does not damage your fish at all and hence is loved by professional chefs around the world.

Boning Knife vs Fillet Knife: The Main Difference

The fillet knife might be the most advantageous tool when it comes to prepping your fish at home, it is not always the most common knife that is included in a kitchen knife set. This is because most home chefs prefer the versatility that the boning knife provides with its option to be used for cutting both fish and meat over better results. This strategy saves money for people but often disappoints when using it for prepping fish.

So if you prefer going for something that will give you spectacular results even if it costs a tad bit more, the fillet knife should be your go-to. However, if you prefer efficiency and versatility in a knife, you should consider going for a boning knife instead.
