List of Top Fillet Knives Reviewed

There’s no question of the importance of having a really good fillet knife. The difference between a dull or unreliable blade and having one of the best fillet knives available for use will be really easy to notice. Following up a great day of fishing with a dull knife that doesn’t want to cut properly is a losing proposition.

Better cuts not only make cleaning and de-boning the fish easier, but makes it faster as well as less likely that you will cut or injure yourself. This is a great combination and when you find yourself able to eat more fish with less bones, that makes the entire meal much easier to enjoy. And nobody wants to hit the emergency room after an errant cut sliced your fingers or hand open.

A really good knife, a little knowledge, and a little experience go a long way in helping you learn how to fillet a fish quickly, fully, and effectively. No mater how good you are, if you don’t have a really good fillet knife that holds an edge, you’re going to have a rough time with the task at hand.

With that in mind, read on to take a look for our best picks for top fillet knives – the type that work as well in the wild off the lake as they do in the kitchen.

custom fillet knife wood handleHonorable Mention for Best Knife: Rapala 7.5″ Fish’n Fillet Knife

Considering they are one of the truly giant names in the fishing industry, it should come as no surprise to experienced anglers that the Rapala name ends up making this list. A long standing standard bearer in the industry, the Rapala name and quality are synonymous – you know you’re getting premium level materials here.

The Fish’n Fillet knife from Rapala comes in several different sizes though the 7.5″ in particular has stuck out as a truly premium option that delivers the absolute best in craftsmanship and functionality that makes it stick out a touch above and beyond even the two other Rapala based Fillet knives on this list.

This seven and a half inch blade is enough to make even deep cuts while having the proper construction and high grade steel to make even the most delicate of cuts when removing the ribs from the fillet itself.

This knife comes with a basic starting sheath that is fully functional and works as a basic knife holder (you can always get a more customized or hand leather carved option if you want some incredible aesthetic to show off later) as well as a single stage sharpener that will help you make sure this knife stays sharp.

A favorite among both beginner and experienced anglers alike, this is one of the highest rated fillet knives you will find on Amazon and anywhere else. The only potential drawback tends to be that some people prefer to go with their own custom sheath as opposed to the one it comes with, but this is a personal taste issue only.

Our Dad always carried his fillet knife in a custom made leather worked sheath, so that is something we understand. As far as the knife itself, Rapala brings the quality that anglers have come to expect from this famous outdoor brand.

When that’s your biggest issue with a piece of fishing equipment is wanting to upgrade the sheath, you’re doing pretty great, although I will say for those of us with very large hands (not barely above average, but actually overly large hands) will find the handle to be a bit small for optimal comfort.

How to Sharpen a Fillet Knife Properly

Main Factors to Look for in a New Fillet Knife

One of the first things you need to consider before buying the right fillet knife (or knives) for you is the species of fish you are most likely to fish for. Cleaning up the catch after a successful day of trout fishing is going to be a lot different than preparing a pan of sunfish, or gutting a big catch after a day of carp fishing.

The reason for this is that the size of the fish often goes hand in hand with how long a blade you want on your fillet knife. While blades can vary from 4 inches to 9 inches, there are several standard sizes that you will see quite often like 4, 6, 7.5 and 9.

In addition to this, quality is a big deal. What is the handle made of? How good is the metal that makes the blade? Is the design likely to hold up over time or is it going to struggle? Do you need a specialty blade like a folding fillet knife or an electric model?

These are important things to consider before looking for your ideal fillet knife. The better the blade, the longer it keeps an edge, the happier you will be with its long-term performance.

If you fish for many different species of fish then you will want to strongly consider getting more than one size of fillet knife that way you’re prepared for whatever ends up on the hook side of your line.

Flexibility & Edge 

Good fillet knives for fishermen are a unique design since they are built for a very specific purpose as opposed to general use. A good fillet knife isn’t just about the quality of steel but it needs to have a decent amount of flexibility to allow for the proper movement around the ribs.

The edge of the knife refers to its sharpness. The sharper the blade the smoother the cut. If you want to cut down on accidents, speed up the fish cleaning process, and end up with the best possible fillets from a day’s catch then you definitely want to go with a knife that has a reputation for being sharp and staying sharp.

Fillet Knife Versus Boning Knife

These are not the same thing! This is important to note because you want a knife that is going to meet all of your fish cutting needs while out on the lake or on that adventurous fishing trip.

A fillet knife is a very flexible boning knife that is designed specifically to filet and prepare fish. While often mentioned as a kitchen knife, any good angler knows the importance of having one with a sheath for all your outdoor fishing adventures.

The special thinness and shape of a blade on a fillet knife gives an angler the maximum amount of movement and versatility to remove skin, cut around the ribs, and cleanly cut the fillets of meat away from the rest.

The Blade Itself

There can be massive differences between the varying fillet knife blades out there. The three most common high quality options are stainless steel, carbon steel, or titanium. Each has its pros and cons, and it can depend on your specific needs. Stainless steel is a great general default choice because they inherently last.

One of the major things to keep in mind: you want a non-corrosive metal. Especially if you are going to be doing a lot of saltwater fishing.

The ideal blade size will also differ depending on the fish that you most often deal with. Big fish with stronger ribs often call for a longer blade with extra sharpness to cut through. Some smaller fish that require a delicate touch might call for a slightly smaller blade. In most cases 6-7 inches is ideal but there are times for longer bladed fillet knives just as there are times and places for shorter bladed fillet knives.

Handle Style & Grip

While the old school handles carved from wood look amazing, and are a particular personal favorite of mine, they often don’t have as good of a non-slip grip as more modern materials like plastics and polymer mixtures. You want handles that fit your hand well, won’t slip when wet, and remain comfortable especially if you are going through a dozen or dozens of fish in a sitting.

While most styles of handles are at least similar in nature, some have more of a curve than others while there are also some that have more of a curve. Look for the type of style or design that feels the most comfortable when in your hand. This won’t always be the same for each angler, and finding one that really suits you is the best way not only to increase efficiency but also comfort.

Electric or Traditional?

We’ve only focused on traditional fillet knives in this particular article because that is the style that all of us are actually familiar with. We’re looking for the best traditional fillet knives and we feel like this blog post does a great job of really covering your best options out there.

There will be a future article looking at electric fillet knives. Many people prefer these and there are pros and cons. Generally, using what you’re familiar with is always the best way to make sure you get the most out of your investment.

Electric fillet knives tend to not be nearly as precise as traditional knives, there is more waste, but when speed filleting a LOT of fish, it’s hard to argue with them as the better choice between these two options.

Fillet Knives FAQ

Q: What sizes do fillet knives come in?

A: While fillet knives can come in any size with blades from 4 inches to 9 inches in length, generally speaking the four most common sizes will be 4 inches, 6 inches, 7.5 inches, and 9 inches. You will be pretty well covered if you have one of each size, and with some research you can find blade lengths at 6.5 inches, 7 inches, and 8 inches without too much extra effort.

Q: What size fillet knife should I purchase?

A: This depends on which type of fish you are going to spend the most time going after while fishing. Smaller fish means smaller blades while going after larger fish means you will need a bigger blade on your fishing knife.

Q: Is there a big difference between basic fillet knives and premium ones?

A: Most of the time, absolutely. While stainless steel might be the standard metal used for these knives, there can be massive differences when it comes to the quality of the metal, how resistant it is to corrosion, and how easily the blade can be sharpened. Premium fillet knives tend to use the really high end stainless steel (or other metal types) and focus on small details that make them a step above your average or budget-friendly cheap fillet knives.

Q: What type of sheath should I use to store my knife?

A: Most fillet knives will come with a sheath. Some will be high quality leather (a personal favorite of mine) while many others will be made from plastic, and the plastic sheaths for these fishing knives can vary immensely in overall quality.

Q: How can I make sure my fillet knife is a good one?

A: There are a few ways to definitely tilt the scales in your favor with this one. There are some names in the outdoor industry that have a reputation for being premium, high end, or simply a little bit better than the rest when it comes to quality. Going with one of these names is always a good way to go.

Another thing to look at are the online reviews that are verified from experienced outdoorsmen. Are there names that keep coming up as a positive? Do some names come out as being not consistently as good? Keep track of all this information to separate the wheat from the chaff.

Q: How many types of fillet knives are there?

A: While this common question is a bit ambiguous, generally speaking there are three types of fillet knives of note. One is the classic model or design, another is the folding fillet knife, and a third is the electric fillet knife. Generally speaking, we never recommend the third because more efficient cuts can always be made by hand, even if it takes a bit longer.

Q: What’s the difference between kitchen fillet knives and outdoor fillet knives for anglers?

A: The knife design is basically the same but kitchen fillet knives are often made with cooking and kitchen preparation in mind. Often times high-end ones will be part of a larger collection of knives that can make for an impressive kitchen collection. There tend to be relatively few differences although the really cheap kitchen fillet knives tend to be especially so since they don’t need to take the beating out in the field that outdoor based knives do.

Q: What are filleting knives?

A: These are knives that feature long thin-blades and are especially good for carving up fish fillets and working around the small bones to remove them without butchering the fillets themselves.

Q: How do I sharpen a fillet knife?

A: The same as a conventional knife. You will need a sharpening stone, and the main difference is the fact that the unique length and design of these blades means paying special attention in how you move that blade over these stones to sharpen the cutting sections of the knife.

Q: What is the difference between a boning knife and a fillet knife?

A: The first thing to understand is that there is some overlap between these two different types of knives. They serve similar purposes and so it is understandable how one could sometimes be mistaken for another. Boning knives are just that: blades that are designed specifically for removing bones from meat. Fillet knives are used for removing both bones and skin from meat, with the overwhelming number of time they are used for fish.

While this isn’t always true, a good rule of thumb is that boning knives are thin blades that are used to carve non-fish meat from bone while fillet knives are the ones specifically used for fish.

In Conclusion

Fishing is a hell of a lot more fun when you have an amazing knife that slices around the ribs and other bones cleanly with no issue, because there’s nothing like freshly fried fish after you have cleanly, quickly, and successfully created a fillet that is ready for batter and frying or butter, dill, chives, and an aluminum foil wrapping.

I have many great memories of some delicious fish just out of the lake, and there’s no question that a sharp fillet knife that allowed quality cutting really makes all the difference for leaving you with clean boneless fillets that are easier to enjoy – and that makes a huge difference when it comes to that overall experience.

Don’t settle for mediocre fillet knives. Make sure you have one that holds up to the test of time today!
