In The Quest For Best Fishing Fillet Knife? Our Top Picks

Are you planning to go on a fishing adventure but don’t have an efficient knife to clean and fillet your catch? Or are you asking yourself, “How do I get a good fillet knife from the many available options?”

No worries, this guide will enlighten you on what to look for in a fillet knife followed by an in-depth analysis of the best fishing fillet knife on the current market.

Best Fishing Fillet Knives: A Comprehensive Analysis

Before deciding to order a knife, you must first evaluate your filleting needs to gauge if they will be fulfilled or not. Here are some key factors to help you.

  • Blade Material

Knives have blades that are generally made from stainless steel, but the quality may vary from one knife to the other.

German-made stainless steel is considered the best followed by Swedish, Japanese, and lastly Alaskan steel. Knives that don’t state the origin of their steel should be treated with suspicion…no wants to end up with fake stuff from China, right?

Nevertheless, the steel should be durable, corrosion-resistant, and strong.

  • Blade Length

This is an important factor to consider when choosing a filleting knife. Generally, blades between 7 and 8 inches are the most common ones.

However, you might want to go for a slightly longer blade or shorter one depending on your needs. For example, smaller knives might be ideal for filleting small fish or if you have small hands.

Concurrently, larger fish may require a knife with a longer blade for efficient handling.

Our review of top fillet knives comprises knives available in multiple lengths to choose from as well as ones available in only one length option.

  • Blade Flexibility

A good knife should bend closer to the handle and should also possess some flex in its tip. This means that a knife with a longer blade is less flexible, while shorter blades are typically known to offer more flex.

Nevertheless, long thin knives are more flexible than the much thicker ones.

  • Knife Handle

Knife handles are made from 3 basic materials, wood, plastic, or molded rubber. Rubber and plastic handles are the best since they have a good grip and are easy to maintain since their construction helps keep germs away.

Wooden handles aren’t too bad either, but they can become slippery when wet or “soak up” the fish smell over time which may later cause difficulties in cleaning.

4. Rapala Superflux Fish n Fillet Knife

Rapala Fish n Fillet


Are you a beginner in fishing and looking for a simple knife to lay your hands on? Then this 6-inch Rapala knife is just the right size, to begin with. You can also as well go for the 4-inch or 7 ½ inch blade knives to test your expertise.

This knife just as its name Superflex has an extra thin, highly flexible blade that enables you to have perfect control over your catch.

What’s more, its razor-sharp blade is made from hand-ground Swedish stainless steel with full tang construction for enhanced durability. Such a type of steel works appropriately in any environment as it doesn’t rust.

5. Morakniv Comfort Fishing Fillet Knife

Morakniv Fillet Knife


The next knife in our review is none other than the Morakniv fillet knife which is available in 2 blade options for more versatility. Firstly, the 3.5-inch blade length which is great for the deboning of fish and filleting of small panfish.

This is followed by the 6.1 inches knife which is efficient for most (or almost all) filleting tasks.

One thing we like about this Swedish-made knife is that it features a Sandvik 12C27 strong stainless steel blade. It is corrosion-resistant and retains its sharpness through extended filleting sessions.

However, the blade seems rigid and has minimal flex. This makes it challenging for you to cut through large fish.

The ergonomically designed TPF rubber handle gives a sure grip even if your hands get wet. Also, the fact that the rubber doesn’t conduct heat makes the knife convenient for all-weather use.

Summing up on the handle, it doesn’t absorb odors and makes the knife easy to clean.

You can use this knife on all saltwater or freshwater fish species as it comprises a corrosion-resistant stainless steel blade. However, the knife does not state the origin of its steel blade, and this is a major downside since no one would like to end up with fake stuff from China.
