Electric fillet knives can help you create precise cuts of fish or meat. The knife can separate the fish fillet from the backbone, the ribs and even the skin of a whole fish without damaging the fish’s delicate flesh.
Fillet knives come in multiple lengths, from 4-9 inches or even longer. The shortest 4-inch knives work well for decorative cuts and for slicing small fillets of panfish, while longer 9-inch knives work best for big fish.
But other factors, including the knife’s balance and the blade’s flexibility, can affect the knife's behavior. It’s not uncommon to see a cook cutting and filleting a piece of fish or poultry with a longer or shorter blade than usual.
The kind of location where you will use the fillet knife also matters. If you only plan to use it at home, you probably don’t have to worry about its construction, but hunters and fishermen need a blade that will hold an edge for multiple uses and won’t rust in wet or damp environments. They also need a handle that won’t mildew or warp.
Grip the knife firmly but not too tightly, and keep your wrist loose. Always cut away from your body to decrease the risk of injury. Store your knife in a dry spot when on a fishing trip. And to remove the skin from poultry or fish, turn the newly cut fillet so the skin is on the cutting board and ease the knife between the skin and meat, pushing away from your body.
The handle needs to fit your hand and feel comfortable whether you hold it firmly or lightly. The handle can be composed of a wide range of materials, including plastic, metal, bone or wood.
Flexibility is a fillet knife’s most important feature. A flexible blade can slightly bend around the tough parts of the fish, so as much meat as possible is separated from the bones in the first cut. Fillet knives have differing levels of flexibility, and each person has their own preference.
It’s crucial to find a balance between flexibility and stiffness, with more flexibility toward the tip of the blade and more stiffness in the blade near the handle. A stiffer blade helps when you’re making extremely thin slices of meat.
Electric fillet knives range in price from about $5-$119. The most inexpensive knives go for $5-$18, while mid-range knives cost about $19-$39 and high-end knives vary in price from about $40-$119.
A. Test it by putting the knife on its side on a cutting board, facing away from you. Lift the handle so only the tip of the blade rests on the cutting board, then gently press down to flex the blade downward.
A. The difference among these knives is in each blade’s purpose. The flexible fillet knife is thin enough to easily slide between the meat and skin of poultry or fish. Boning knives have thick, stiff blades that can tear through the skin, making it more difficult to separate from the meat. Cooks who fillet both poultry and fish and don’t want to continually switch from one blade to another might like a hybrid knife.
A. The curved end and severe taper of the blade’s final third make it feasible to perform intricate cuts of fish and meat. For instance, when you’re filleting a panfish, it’s recommended to make an initial cut along the backbone, and the tapered end of the knife is the best part to make this shallow cut. The upward taper also helps with decorative cutting of fruit and vegetables, letting you make curved, precise slices.
