To many, a knife is a tool used for cutting, shearing, slicing among other similar functions – a simple tool for a simple task, right?. Nothing is ever so simple, however, in life. There are all sorts of different knives for all kinds of unique applications.

This guide will focus on the fillet knife, a specialized type of knife used to cut/slice and separate flesh from bone and skin from the flesh. We hope the guide will give you a better understanding of fillet knives and arm you with the information you need to help you select the best fish fillet knife or knives to suit your needs. 

Lastly, we have recommended 10 fish fillet knives with descriptions, details and specs for you. They were carefully selected based on the high quality, exceptional functionality and good value they offer. Enjoy!

What Is a Fillet Knife Used For?

One of the best ways to transform your catch (fish) or meat into a juicy meal is by making use of a fillet knife. They may sometimes be mistaken for boning knives but, although they may seem similar and may have overlapping functions, there are still some important differences.

For one, fillet knives are thinner than boning knives and are more appropriate for separating skin or fish from bone, primarily due to their thinness and flexibility.

But, perhaps, the most important difference between the two knife types is the flexibility of a fillet knife. A flexible knife conforms better to the contour of the fish to yield a more precise cut and reduce waste. That, combined with its thinness, gives today’s best fish fillet knives the ability to cut and slice with a precision that a pure boning knife just cannot match.

Professionals will tell you to use the best fillet knife you can get your hands on, as making use of the wrong knife when cutting fish or meat away from bone can go wrong really fast.

Making use of the wrong knife increases the risk of slicing yourself and wasting your fish or meat. The wrong or inferior knife may also struggle to hold its edge, losing its sharpness in a very short fashion.

Using a good fillet knife for fish will, therefore, allow you to avoid all of these potential problems and give you the best results in the kitchen – or out on the water. But exactly what makes for a good fillet knife?

Blade Choices – Stainless Steel or High-Carbon Steel?

Let’s start with the blade composition because that is the most important part of any knife. In its basic form, all steel is a combination, or alloy, of iron and carbon, with carbon acting as the glue that gives the mixture its hardness and prevents it from breaking down.

All steel knives, including those for filleting, begin with this simple process. However, our modern knives are more sophisticated than that as manufacturers must fine-tune the basic formula to make the best product for different applications.

Because a fillet knife will be used for slicing meats and fish that require precise cuts while frequently exposed to wet environments (including corrosive salt water), a good fillet knife should ideally have a blade that is durable, sharp and corrosion-resistant.

With that being said, knife manufacturers add other elements including chromium, molybdenum, tungsten, magnesium, as well as others, in varying degrees of quantity to achieve particular results.

The knife blades we have today fall into essentially two camps:  stainless steel and high-carbon steel. But even so, you will find plenty of variants of these two main categories on the market, including the high-carbon stainless steel versions that contain more chromium than standard high-carbon steel and offer the best of both worlds.

These more expensive hybrids are still essentially high-carbon steel products but with better protection against corrosion.

Let’s take a brief look at the main differences and advantages/disadvantages between stainless steel and high-carbon steel:

Stainless Steel Blade


  • Tends to stay attractive longer over time longer
  • Generally, more durable (e.g., less prone to chipping)
  • Requires less maintenance
  • More corrosion and stain-resistant
  • Easier to sharpen (generally; some disagree)


  • Easier to break
  • Decreased sharpness and edge retention

High-Carbon Steel Blade


  • Stronger and harder blade
  • More flexibility
  • Sharper blade edge (less effort, more precise cuts)
  • Maintains its edge better over time (edge retention)
  • More affordable (usually)


  • Less stain and corrosion-resistant
  • Requires more maintenance (mainly for corrosion prevention)
  • Easier to chip (try not to drop it!)

German vs Japanese Steel Blade

The German steel blade is an extremely popular choice when it comes to cutlery. The German variant is especially unique because with its lower carbon content the blades are softer, thus making them more durable as well as better at keeping an edge over a longer period of time.

Japanese carbon steel blade knives, on the other hand, have a higher carbon count than their German counterparts. This means they can be made with a thinner/lighter profile, yet be harder (generally, higher Rockwell hardnessHRC – ratings) and extremely sharp for more precise cuts/fillets. The harder steel, however, can make this blade more susceptible to chipping, and even cracking.

The choice between a Japanese or German steel blade, again, comes down to personal preference and what qualities are most important to you. The differences between the two are not great. The important thing to remember is to buy the best quality you can afford, regardless of type.

Blade Flexibility and Size: They Matter

man cutting fish fillets

As mentioned before, it is the flexibility, to a great degree, that helps to make the fillet knife what it is. It is therefore ideal for a good fillet knife to be flexible. This will allow for tight-angle maneuvers for an easier time filleting. This produces great results and allows you to get the most out of the fish while avoiding injuries to your hand.

How big a knife? Depending on the size of the meat/fish you’re preparing, there are several options. The fillet knives on today’s market typically range from 4 to 10 inches in size. However, a knife of 6 or 7 inches is generally ideal for most applications while also being convenient for storage and transport.

Get a Grip – Handle Material

The handle is the second most important component on a knife, particularly one used for filleting. Even experts will have a hard time filleting with a knife with a poor grip. There is often a tendency for the knife to slip off and this can get tiring, if not downright hazardous, really fast.

Besides a good grip, the handle of a fillet knife should also be ergonomically designed to allow for maximum comfort while cutting. Also, should be made from materials that are durable, do not hold in fish odors and are easy to clean. Lastly, there is no reason why a fillet knife handle cannot also be aesthetically attractive – in fact, this is often a strong selling point.

Some of the best knife handles are made from Pakkawood, a strong, durable and attractive hardwood composite frequently used for fillet knife grip.

Other popular fillet knife handle materials include synthetic polymer rubber and plastics, chosen for their comfort and grip, Birchbark, a beautiful and natural material that is comfortable, waterproof and resistant to rotting,

Curly Birch, another naturally beautiful and durable handle material is also often used in knife-making and, in some instances, bare metal, as with one of the knives in our recommendations below, is all that is needed.

Full Tang vs Partial Tang

Every knife has a tang, that metal part of the knife that extends into the handle, partially or fully. The tang is the unsharpened portion of the blade to which the handle, whether made of wood or some synthetic material, is attached.

In a partial-tang knife, the tang extends only partly and you will not see it as it is usually hidden in the handle. On a full-tang knife, it runs the length of the handle and maybe hidden or visible.

When visible, you’ll often see it as that thin metal slither sandwiched between the handle material that is usually attached by rivets on both sides. You’ll find several variations of each type of tang on the market but they still belong to one of the two primary types.

Partial tangs have their place and can be found on some very good fillet knives. They can be produced faster, at a lower cost and make for a lightweight knife that won’t fatigue the user with extended use. They are also more accommodating of delicate and, often, exotically beautiful wood and other materials. But they also have their limitations.

That they lack the straight-through strength of the full-tang fillet knife is probably its biggest drawback. The weight savings, realized by not using a full and heavier tang, will make it less durable and balanced than its full-tang counterpart.

Full-tang fillet knives are inherently superior in strength and durability. Though they tend to be heavier than partial-tang varieties, the perceived liability is quickly offset by the more balanced feel when cutting.

I also like the fact that you can lean into them more without fear of impending disaster. In the end, they are usually more costly but well worth the extra expense when you consider long-term performance.

Electric Fillet Knife vs Regular: Speed or Precision?

Choices for fillet knives come down to manual and electric models (which also includes the cordless fish fillet knife). An electric fish fillet knife is a great option if you have lots of fish you want to fillet in bulk and fast.

They do, however, require a little getting used to, but once mastered produce good and fast results. There are several excellent models on the market today from which to choose if you prefer them over manual ones.

It is really just a case of picking whatever suits you best. However, many experts (I tend to agree) argue in favor of manual fillet knives because they tend to produce more precise and desired results.

So, for our guide, we have chosen 10 of what we feel are some of the top manual fish fillet knives currently available for purchase. But, we have also listed, here, what I believe are some of the best electric fish fillet knives on the market.

Our 10 Best Fish Fillet Knife Recommendations

Any knife is intended to be held in the hand and a fillet knife is no exception. A good fillet knife should not cause any constraints on the hand. A good fillet should not be too heavy – longer, thicker blades will be much heavier than their shorter, thinner counterparts.

Additionally, the materials used to make the blade not only impacts the weight but also its quality, performance, and durability. Therefore, the blade material also needs to be considered along with design features when choosing a fillet knife.

There are plenty of good fillet knives for fish on the market from which to choose. The 10 recommendations in this section are top-rated and recognized for their workmanship, quality, and value. Let’s take a closer look at each.

See DALSTRONG Phantom Series 6.5″ Fillet & Boning Knife on Amazon

A DALSTRONG product is featured again here on our list. This time it is an offering from the knife maker’s widely popular Phantom Series featuring a high-carbon Japanese steel dual-purpose fillet/boning blade.

A Japanese blade is usually designed to be more lightweight due to the blade tapering off in the handle as opposed to the traditional full tang design of German-made steel knives. The Japanese-made steel is also thinner, which gives it excellent flexibility, and a sharper edge. High Levels of chromium added to the steel increases its resistance to corrosion and stains.

See Shun 6″ Classic Boning & Fillet Knife on Amazon

Another highly-rated and stylish knife is the 6-inch blade Shun Cutlery boning and fillet knife. This high-performance, hand-crafted Japanese knife is another best-selling, multipurpose knife that can be used for boning and filleting. This knife will slice through a rib roast and tuna with the same precision.

What makes this knife such a standout is Shun’s proprietary VG-MAX advanced steel. The advanced formula increases the use of certain metals to achieve desirable results. For example, the company added more carbon for better strength and durability, more chromium for greater wear and corrosion resistance and vanadium for improved cutting performance.

While not as flexible as some of the other knives in the guide due to its dual-function design, the Shun Cutlery Classic makes up for it with its incredibly sharp and accurate blade. Cutting meats and filleting fish with this knife takes very little effort. A meaty and attractive black Pakkawood handle offers a secure grip while working with the knife.

Also, it’s a little weighty (I kinda like the feel of a heavier knife) but as a multipurpose fillet knife that can also serve as a boning knife, I find the little extra weight acceptable. As an added bonus, Shun will sharpen your knife free of charge for as long as you own it!

Knife Specs:

  • Blade Type: Japanese High-Carbon Steel (VG-MAX Steel)
  • Dimensions: 11″ x 0.9″ x 1.8″

Frequently Asked Fillet Knife Questions

Q: Who Makes the Best Fillet Knife?

A: That’s a tough question and the answers can be quite subjective – kinda like asking who makes the best car? You’ll get more opinions than you bargained for. There are so many good knife makers who put out quality fillet knives of varying price points.

What I will say is that the 10 knives in this guide are some of the best, made by the world’s top-rated knife manufacturers such as German maker ZWILLING, one of the oldest brands in the world, having opened their doors in 1731.

Q: Which type of Fillet Knife is Best for Fish, Stainless Steel, or High-Carbon Steel?

A: What is best will depend on you and your intended use. If you want precise cut fillets of fish and are working mainly in your kitchen, I would favor a high-carbon model. You’ll get a knife that has a really sharp edge, maintains the edge longer and will cut with a little less effort.

Of course, you must maintain it by wiping and drying it off as soon as you’re done – and sharpening it using a quality knife sharpener according to the manufacturer’s recommendations.

However, you if are going to using your knife to fillet fish by the lake or, in particular, around saltwater, I would choose a stainless-steel knife for its superior corrosion-resistant properties. It really depends on your particular application.

Q: Why Bother with a German Carbon Blade if the Japanese Blade Is Sharper?

A: Well, if being sharper were the only consideration, I would say go for it. But there’s more to a good fish fillet knife than blade hardness or sharpness. You also have to think about how long the blade will stay sharp with frequent use or, better yet, how often do you want to be sharpening the blade.

Yes, the Japanese high-carbon blade will be slightly harder and sharper and give you some excellent fillets but, if you want a blade that is perhaps a little more durable and can go longer without having to be sharpened, a German blade knife might be a better choice. Again, it really depends on how you intend to use the knife.

Q: What Size Knife Do I Need to Fillet Fish?

A: Assuming we are talking about the length of the knife blade, the size depends on what you are going to be filleting. If you are going to be filleting small fish like crappie, bluegill, and mangrove snapper, a fillet knife with a blade of 5 – 6 inches should be sufficient. For bigger fish such as walleye, trout, or striped bass, a 6″ – 8″ blade knife may be necessary.

The best fillet knife for saltwater fish like mahi-mahi and larger salmon will be one with a blade of 9 inches and above. Size comes down to the size of the fish you plan to fillet. A medium-size fillet knife in the 7-inch to 8-inch range, such as the ones in this guide, should be perfect for most needs.

Q: Wouldn’t It Be Easier and Better to Use an Electric Fillet Knife Instead of a Manual One?

A: Easier? In some cases, yes. It may be easier using an electric fillet knife in the sense that you will have to put less effort into filleting as the electric knife’s motor does most of the work.

Electric knives are also great time-savers, particularly if you have a bunch of fish you need to fillet. You could probably get them done in half the time and not even break a sweat. There are many people who love using their electric knives and would never go back to manual fillet knives.

But better? Not necessarily. While the electric knife excels at speed and convenience, the regular or manual fillet knife is a tried and true tool that does certain things better – in the opinion of many, this writer included. For starters, a good, standard fillet knife will give you better control and precision when cutting than even the best electric fillet knife.

The more ergonomic and less bulky knife handle combined with a thinner and more flexible blade will let you have a better feel as you fillet along the fish’s bones. You will usually get thicker and better-looking fillets with less wasted flesh. This is particularly true if you are filleting smaller fish.

Lastly, keep in mind that an electric knife will require a bit of a learning curve before you can master it. It is more intuitive and easier to learn with a standard knife, giving good results with just a little practice.

Wrapping Things Up

    Having lived in Japan for 2 years back in 2010, I only trust their knives when it comes to fish. They are BIG TIME fish eaters and the way they prepare the fish over there is unmatched. It all starts with a proper cut from a good blade. I once had a set of knives from Japan. I don’t know the English name for them but they are stellar. I will have to see if I can find them for sale in the US online and report back.

      Hey Dale, thanks for stopping by. You are correct, the Japanese certainly know a thing or two about fish prep. Let us know when you recall that Japanese knife brand.
