Best Fillet Knife in 2021 – Tested Reviewed with Buying Guide

Imagine reeling in that prized redfish, trout or salmon during a fishing expedition. Your next thought would dwell on how delicious it would be on your plate tonight. Well, that thought becomes a permanent imprint on your mind after filleting.

Having the best fillet knife is a huge bonus for any angler. You can easily prepare fish right on the boat before you turn in. That way, you’re sure your next stop after the fishing hole is your kitchen pan.

Sadly, there are tons of brands out there, most of which are of terrible quality. Some aren’t even fishing-friendly- breaking or corroding easily after a few uses. Having to change your fillet knife too regularly can be a total drag to your fishing hobby.

There’s also the issue of taste. I’ve come to notice that I like my fillet knives thinner and smaller. Others might prefer those with shorter handles. The point is, preferences differ. So, it’s good to understand what to look out for in a good fillet knife. Lucky for you, I’ve compiled a list of the best products on the market for you to choose from.

When Are Fillet Knives Necessary?

A fillet knife is basically a fish cutting knife. Like a fillet fork, it is specially designed to clean fish before preparation. They’re fashioned to remove scales, bones and cut fish clean off the spine. They’re also flexible enough to move cut smoothly under the flesh.

Fillet knives are very different from other knives. They’re thinner than boning knives, allowing them to easily move through fish. They’re also thicker at the ends and pointer at the tips than carving knives. This allows more strength and easy picking of bones.

With a fillet knife, you can cut and clean efficiently, whether in your kitchen or on the boat. It’s your best bet for trimming fat, deboning, descaling and cutting through fish with ease. Surprisingly, these utensils are also very handy for preparing vegetables and segmenting citrus. And they’re also good for carving smaller food like carrots or radishes.

A fillet knife is a great addition to your kitchen. If you’re an angler, this handy tool makes preparing fish much easier. It’s also a great companion for those who regularly prepare fresh fish, professionally or as a hobby.

If you fall into the general category of those who regularly prepare fresh fish, you need to pick the best fillet knife for you. Hopefully, our fish fillet knife reviews would help you learn how to do that and even give you options to pick from.

Best Fillet Knife for The Money – A Comprehensive Buying Guide

A good fillet knife is a difference between cutting fish like a pro and stabbing your fist in frustration. You want to go for something that gives you good value for your money. You need a blade that works as an extension of your very arm, cutting as precisely as you want. As such, you must consider the following factors before purchasing any fillet knife.

1. Design & Size

The combination of all its parts determines the overall design of the fillet knife, so it must be considered. The type of blade, thickness, handle material and specification of use will determine how the blade looks and feels. High-end knife models will be ergonomically satisfying and functionally effective.

It also determines what it works best for. Straight-edge blades are great for precision cuts. Serrated edges easily cut through tough scales and tapered tips Also, fillet knives come in small, medium and large sizes. What you choose depends on how large your catch is and the precise purpose of use.

The most common colors for the handles are white, black, blue, rainbow, teal, cyan, orange, purple and yellow.

2. Blade

All knives are basically made up of the blade and the handle, with the blade being the cutting part. Before picking a fillet knife, analyze the following blade properties; its material, its size, and its sharpness.

  • Blade material

What is the blade made of? How sturdy and durable is it? Is it easy to sharpen? Is it rust and corrosion-resistant? Does it clean easily? All these are questions to be asked.

Generally, stainless steel is the most used blade metal because it is most versatile while high carbon steel sharpens best. Titanium steel is also used though, these are usually more expensive. Whichever you choose, make sure the material is also of high quality.

  • Blade size

You need to ask yourself if the size of the blade improves or hinders functionality for you. Blades come in varying lengths and your choice is based on how large the fish is.

Smaller fish like bluegills require more precision and that is best achieved with shorter blades (preferably around 5 inches). Blades around 7 inches are considered ‘all-purpose’ and are suitable for averagely sized catches such as crappie, panfish and bass. And for larger fish such as salmon, blades longer than 8-9 inches should be considered.

  • Sharpness

Fillet knives are basically made for precision. So they must come with razor-sharp edges that can cut precisely and finely through fish. The edges should also be able to hold well and not blunt too quickly. Plus, you need to make sure the blade sharpens quickly and easily to maintain the edge.

3. Handle Material

The handle is the controlling part of the knife. The type of material used must be compatible with preparing and cutting fish. Cutting fish releases lots of water, slime, and blood so you’ll need a handle that doesn’t slip easily.

The material used must also be comfortable for long use in cases where you need to work on lots of fish. Good fillet knives come with wooden, rubber or plastic handles. When choosing, go for the type that agrees with your handling. However, the old vintage models are more likely to have wooden handles.

4. Comfort & Grip

Also, ensure that the grip of the knife is solid and firm. Make sure it doesn’t slip easily or you’ll wind up cutting yourself more often than the fish. A good fillet knife will feel comfortable and sturdy to your grip, regardless of the condition.

Using a fillet knife requires you to feel right when handling it. That way, you can cut and fillet with much ease. The right fillet knife for you is that which feels natural in your hand. Make sure the handle material is comfortable to your grip and doesn’t make your hands ache. You’ll appreciate this when you’re preparing lots of fish.

5. Strength

The thickness of the fillet knife blade determines its strength. Thicker blades are usually stronger and easily cut larger fish. Thinner blades, however, might have you struggling through that tuna. Before selecting one, ask yourself if the blade is thick enough to slice through your catch. Be assured that professional-grade knives wouldn’t fail you in the strength department.

6. Flexibility

When filleting fish, you would have situations where you need to bend the blade for better precision. This refers to the blade’s flexibility. Thinner, shorter, and smaller blades tend to be more flexible, allowing easier deboning and precision cuts. If your knife is thin, there’s no homemade or handmade remedy, and you should be buying a thicker one. You can work on making the handle more personalized though, attaching extra gripping material over it.

Flexibility is often looked for when the fish to be filleted is small. Thicker blades are usually less flexible as this is not usually required when cutting larger fish. They make up for this by offering strength in size and length.

7. Safety & Hygiene

Filleting brings you in contact with a lot of blood and bacteria, especially with freshly-caught fish. This is why it is important to purchase a knife with safety features. Most fillet knives have dimpled handles to ensure firmer grips. Others come with finger guards between the handle and the blade junction.

Also, good sanitary features must be present on a fillet knife. There must be no gap between the blade and the handle at the meeting point. This avoids the accumulation of materials that can breed bacteria in areas that are hard to clean. A good fish fillet knife must be easy to clean.

8. Purpose

Perhaps the most important question to ask when buying fillet knives is ‘why’. Different fish and different situations require different fillet knives. In order to get a great deal, you must ensure the knife will serve the purpose efficiently.

Smaller fish require shorter, thinner, more flexible fillet knives. Larger, stiffer, longer knives work best on tougher tasks synonymous with a bigger catch, especially saltwater fish. And freshwater species can be easily prepared with medium-sized fillet knives.

Indoor tasks and bulk filtering are best performed with an electric fillet knife. Manual knives are your best bet for outdoor use as they don’t need a power source. These can be carried in different fishing spots with you. They are tiny enough to fit a fishing backpack. Some models come with a spoon attached to the knife butt, this particular part can be used for scaling the fish before slicing the flesh.

9. Electric vs Non-electric

Originally, fillet knives are used like regular knives giving you complete control over cut depth, precision, and flexibility. However, some electric sawzall type knife models are also available. These make filleting a large quantity of fish faster. Many even come with different changeable blades so you can work on a wide variety of fish. The battery-powered models are also available. These models come with rechargeable batteries.

Many users, though, prefer to be in full control of the fillet knife and opt for the non-electric models. Non-electric means manual. In the end, it boils down to what you prefer, and if time is an important factor.

I’m Derrick in my early 40s, but planning to bag from every saltwater source in America. In practice, I’ve explored over a dozen bodies of water that hosted almost all of the saltwater game fish. My personal favorites are brook trout and striped bass though. I don’t mind catching bluegill and white crappie either.
