Choosing the right knife for filleting fish can be a bit of a challenging task and that is because there are so many options out there. Depending on what you need the knife for, there may be special requirements placed on the knife. Fish fillet knives are going to have some different features than your normal meat fillet knives. Blade size is usually a factor with the normal sizes ranging from 4 inches to 9 inches. This is going to change depending on the fish you are looking to fillet.
