Best Fish Fillet Knife: Buying Guide

Blade size and material

In general, fish fillet knives have blades that range from 4 and 9 inches in length. The standard sizes are 4, 6, 7.5, and 9-inches respectively. There is quite a variety when it comes to blade sizes and the reason is because fish vary a lot.

So, when buying a fillet knife, you need to have an idea of what type of fish you plan to be using the knife on in order to determine the appropriate blade length. Bigger fish require the use of a longer blade due to the wide girth and large surface area, while smaller fish can be filled with a shorter bladed knife.

For target fish like crappie and bluegill, 6-inch blades are ideal. Bass and small trout have an ideal blade length of 7.5 inches and fish like pike and salmon usually need a 9-inch blade.

To get the most out of your fillet knife, you could opt for a “general” blade size which is usually 7.5 inches. This size blade will allow you to fillet both small and large fish with minimal struggle.

In terms of blade material, most knives are made using stainless steel. This being said, not all stainless-steels are the same when it comes to quality. Most companies don’t specify which type of stainless-steel is used, but, if you can, try to find a blade that has been made from high-carbon stainless-steel or from a reputable manufacturer.

Handle

Although the blade is the star of the show, the handles of knives are important also. Grip, comfort, and ease of use are all derived from a well-constructed, durable handle. A good handle ensures that you can wield the knife with ease and reduces the chance of injury.

Wood, plastic, and rubber are the most popular materials that handles are from, with wood being the most traditional option. Wood is durable and easy to clean but has a tendency to get slippery when wet. It can also trap the smell of fish within it.

Both rubber and plastic are easy to clean and resistant to corrosion. Plastic, like wood, can get slippery, while rubber is the best option if you’re looking for the best grip possible.

In addition, a good handle will have a beveled area between the blade and the handle. This serves as an extra layer of protection against slippage, while also providing the user with extra leverage.

Hardness and flexibility

You’ve probably noticed the range of prices among fillet knives. Price is generally based upon the quality of the blade. Blade quality is how hard or soft the blade is.

A quality blade should be flexible and made from a hard, sturdy metal. The metal should allow enough flex and bend for you to maneuver your knife around bones and inside the various portions of meat without breaking.

It should also be made of a metal that’s hard enough to maintain its edge. On the Rockwell scale, which is used to determine the hardness, knives with a rating of 55-61 are considered to be the hardest.

Sharpness

Blade sharpness is another factor to consider. How sharp the blade is will determine how clean your cuts are.

The best blades will come pre-sharpened and ready to go, as well as hold their edge well. They will also be easy to sharpen and might even come with their own sharpener.

Fillet Knife Styles: Japanese vs. German

There are two main knife styles: Japanese and German (also known as Scandinavian). They are relatively similar but have minor differences that are worth noting.

Japanese

Japanese style knives tend to have a single-beveled blade that is both thinner and more lightweight. They are ideal for making clean, straight cuts since the blade have a less severe angle. The stainless steel used is known for being harder than most other types of knives, making it sharper.

German

German knives are often graced with double-beveled blades – these are blades that have been sharpened on both the left and right sides. The blade usually has a severe angle, making it great for chopping. The blade is often heavier than the Japanese-style blades, making the knife generally heavier. However, steel is often a bit softer.
