These are the 10 best fillet knives available online. But before you make a purchase, read through the following buying guide.

What To Consider Before Buying The Best Fillet Knife 

  • Blade Material: Select a fillet knife made of a highly durable blade. While most knives use stainless steel, there is a huge disparity in the quality of steel used. We suggest going for a blade made of high carbon stainless steel due to its extreme flexibility, durability, and strength. 
  • Handle Material: The most commonly used handle materials are wood, rubber, and plastic. While all three are easier to clean and corrosion-resistant, wood is the most durable (but it traps odors). A rubber handle would offer the best grip. While plastic is far lighter, it can be slippery when wet. 
  • Blade Size: Blades usually come in standard sizes of 4, 6, 7.5, and 9 inches. Bigger fish demand knives with longer blades while smaller fish can be worked on with a shorter blade. To be more specific, 6-inch blades are ideal for crappie and bluegill, 7.5- to 8-inch blades suit bass and small trout, and pike and salmon warrant 9-inch blades. However, a knife with a 7.5-inch blade can be easily used to fillet both small and large fish without any hassles. 
  • Sharpness: The best fish fillet knife comes in a pre-sharpened condition and offers several design components to ensure sharpness. Some also come with sharpeners. Ensure your fillet knife is as sharp as you need. 
  • Flexibility: Unlike your usual kitchen knives, a fillet knife requires extreme flexibility to get you the clean cuts and scaling that you desire. The best fillet knife should have a sturdy metal that offers high flexibility and allows you to easily maneuver across the bones.

Conclusion

Fillet knives are a great addition to your kitchen, especially if you are a seafood lover and prefer cooking your own food. Now that you are aware of the best fillet knives available online, you may go ahead and make your selection. We are sure you will be happy with your purchase. 

Expert’s Answers for Readers Questions

Which is the best fillet knife for saltwater fish?

The Rapala Soft Grip Fillet Knife works best for delicate species like the saltwater fish.

Can I wash the knife in a dishwasher?

Just as most knives, a filet knife should also never go into a dishwasher. The detergents can cause abrasions and make the knife blunt. It is best to wash your knives in the sink using your regular dish soap and water.
