Sharpness and edge retention

It may come as no shock to anglers that a sharp fillet knife is one of the most important, if not the most important factors, and for that matter, for any knife in general regardless of its intended purpose.

Sharp fillet knife reduce tearing of the soft meat and help you get clean cuts and remove skin if needed.

Edge retention is the product of using high quality steel, and the higher carbon density and quality will translate to holding that razor sharp edge for longer.

Materials and construction

Stainless steel used in almost anything that has to do with fishing or marine environments is critical to reduce corrosion.

Other materials to consider are handle materials, which in many cases may boil down to personal preference, but a handle that ensures a solid grip and stays firmly around the tang is also important.

Full tang construction is great, it ensures that no issues will result in the knife bending or breaking free from the handle above the handle.

Grip and handle

You also want to ensure that it is ergonomic as well as safe, with little potential for your hand to slip forward and onto the blade.

Thickness

When it comes to thickness of fillet knives the simple answer is the thinner the blade the better. With that being said you need to consider the fish you want to clean with it as well, as large fish will be difficult to fillet with too thin of a blade.

Flexibility

Type: Japanese or German/Scandinavian style

Japanese style blades are great for precise work and have been designed to sushi and other types of fish presentations.
