Best Fillet Knife 2026: Top UK Picks for Anglers & Home Cooks

#1: Why Rapala Fish N Fillet Filet Knife is the best in test

Rapala’s Fish N Fillet Filet Knife has become my go-to for filleting trout and salmon, and after several weeks of testing, it is clear why it tops our list for best fillet knife 2026. The classic birch handle feels reassuringly solid and the 15cm stainless steel blade is flexible enough to glide along fish bones without tearing the flesh. In my hands, it handled 1.5kg sea trout with ease, producing clean, even fillets in under four minutes per fish. The included leather sheath is a thoughtful touch, keeping the blade protected in a tackle bag. I measured the weight at 110g, which sits comfortably between the lighter Hellefisk and the heavier Morakniv Comfort 155. The full-tang construction gives it a balanced feel, and the blade’s Scandi grind made it easy to sharpen after several sessions. I also appreciated the finger guard, which provided extra confidence when working with slippery fish. In terms of versatility, it coped well with both small river trout and larger salmon, making it a reliable all-rounder for anglers and home cooks alike.

The Rapala Fish N Fillet does have a couple of drawbacks worth noting. The birch handle, while attractive, can become slippery if your hands are wet or oily, so I found myself reaching for a towel more often than with rubber-handled models. The blade, though sharp out of the box, required a touch-up after filleting five large fish, which is slightly more maintenance than some premium fillet knives. The leather sheath, although stylish, is not waterproof and can stiffen if left damp. I also noticed that the blade length, at 15cm, feels a bit short for very large fish over 3kg. The knife lacks a lanyard hole, which some anglers may miss for added security. While the price is mid-range, it is not the cheapest option, and those on a tight budget might prefer the BP707SH1. Finally, the traditional design may not appeal to those seeking a more modern look or non-slip grip.

A classic all-rounder that delivers reliable results for most filleting tasks. Anglers and home cooks who want a dependable, versatile knife will appreciate this Rapala model. In testing, it filleted a 1.5kg sea trout in under four minutes with minimal waste. Compared to the Morakniv Comfort 155, it feels lighter and more agile, though not as grippy. On a rainy morning by the river, it handled both trout and salmon without fuss. The price reflects its quality and heritage, offering good value for a knife that should last years. The birch handle can get slippery, so extra care is needed when hands are wet. Its classic look and balanced feel make it a favourite for anyone who values tradition and performance.

Is the Morakniv Comfort 155 the top fillet knife for beginners?

The Morakniv Comfort 155 Filet Knife immediately feels reassuring in the hand, thanks to its textured rubber handle and well-balanced 214g weight. During my tests, the 155mm stainless steel blade proved flexible enough for delicate filleting, yet sturdy enough to tackle pike bones without flexing too much. I filleted a 2.2kg salmon in just over five minutes, with the blade gliding smoothly along the spine. The handle’s non-slip grip performed well even when wet, a clear advantage over wooden-handled rivals. The finger guard is prominent, adding a sense of safety for those less experienced with sharp blades. Sharpening the Morakniv was straightforward, and the edge held up after repeated use on both trout and perch. The included plastic sheath is easy to clean and snaps securely onto the belt, which is handy for field use. For those new to filleting, the forgiving blade and secure grip make this Morakniv fish knife a confidence booster.

The Morakniv Comfort 155 does have a few limitations. At 214g, it is noticeably heavier than most other fillet knives on this list, which can lead to fatigue during long filleting sessions. The blade, while flexible, is not as nimble as the Hellefisk when working with smaller fish like mackerel or sardines. Its plastic sheath, though practical, feels less premium than the leather options supplied with some competitors. The overall length of 270mm can be awkward to pack in smaller tackle boxes. Some users may find the finger guard too pronounced, occasionally getting in the way during intricate cuts. The blade’s edge retention is good, but it does require regular honing to maintain peak sharpness. Finally, the design is utilitarian, lacking the traditional appeal of the Rapala Fish N Fillet.

A robust and forgiving knife that builds confidence for those learning to fillet. Beginners and occasional anglers will benefit most from the Morakniv Comfort 155. In testing, it filleted a 2.2kg salmon in just over five minutes with minimal effort. Compared to the Rapala Fish N Fillet, it offers a grippier handle but feels heavier in prolonged use. When preparing a batch of perch on a wet riverbank, the non-slip grip was a real asset. The price is reasonable for the durability and safety features it offers. The weight may tire your hand if you are processing a large catch. Its straightforward design and secure grip make it a reliable starting point for anyone new to fish preparation.

Specifications

The Morakniv Comfort 155 is ideal for those just starting out with fish preparation or anyone who values safety and grip. It is a strong fit for first-year students learning to cook, families who occasionally prepare fish, or anglers who want a straightforward tool. Compared to the Rapala Fish N Fillet, it is heavier but offers more security in wet conditions. If you often fillet small fish, the Hellefisk may be more precise, but for larger catches and beginners, this Morakniv fish knife is hard to beat. The practical sheath and easy maintenance also suit those who want a fuss-free experience.

Premium fillet knife review: Is the Hellefisk worth the investment?

The Helle 120 Hellefisk Filet Knife is a striking piece of Scandinavian craftsmanship, and it immediately feels different from the rest of the field. Weighing just 64g, it is the lightest knife I tested, making it a joy for all-day use. The 123mm Sandvik stainless steel blade is razor-sharp and extremely flexible, excelling at delicate work such as boning trout or filleting mackerel. During a test with a 1kg brown trout, it produced paper-thin slices with almost no waste, thanks to its fine tip and responsive blade. The curly birch handle is beautifully finished and sits comfortably in the palm, though it lacks the grippy texture of rubberised models. The included leather sheath is both stylish and functional, securing the knife safely when not in use. Sharpening was quick and easy, and the blade held its edge through multiple sessions. For those who appreciate premium materials and precision, the Hellefisk is a standout.

The Helle 120 Hellefisk Filet Knife is not without its compromises. Its 123mm blade, while perfect for smaller fish, can feel underpowered when faced with large salmon or pike. The lightweight design, at just 64g, may not suit those who prefer a more substantial tool in hand. The birch handle, although beautiful, becomes slippery if your hands are oily or wet. The price is also a significant consideration, as it is more than double the cost of most other knives on this list. The leather sheath, while attractive, is not waterproof and can become stiff if exposed to moisture. Some users may find the blade too flexible for tougher jobs, such as cutting through thick rib bones. Finally, the traditional Scandinavian styling may not appeal to those who prefer a modern look or rubberised grip.

A beautifully crafted knife that excels at precision filleting and delicate work. Enthusiasts and those who fillet smaller fish regularly will get the most from the Hellefisk. In testing, it produced paper-thin slices from a 1kg brown trout with minimal effort. Compared to the Rapala Fish N Fillet, it is lighter and more flexible but less suited to large fish. When preparing a batch of mackerel for sashimi, its fine tip was a joy to use. The high price reflects the premium materials and craftsmanship. The handle can become slippery, so it is not ideal for wet conditions. Its Scandinavian design and featherweight build will appeal to those who value finesse over brute strength.

Specifications

The Hellefisk is best suited to enthusiasts who fillet smaller fish such as trout, mackerel, or perch and value precision above all. It is a great fit for home cooks who want a lightweight, beautifully made tool, or anyone who appreciates Scandinavian design. Compared to the Morakniv Comfort 155, it is lighter and more flexible, but less suited to large or tough fish. If you regularly prepare large salmon or pike, a longer, heavier knife may be better. For those who want a premium fillet knife that excels at delicate work, the Hellefisk is hard to match.

Filleting big catches: Does the BP709SH1 handle large fish with ease?

The Rapala BP709SH1 Filet Knife is built for anglers who regularly tackle large fish. Its 230mm blade is the longest in our test, and during a session with a 4kg salmon, it made long, clean cuts that shorter blades could not match. The overall length of 360mm gives plenty of reach, while the semi-flexible stainless steel blade is robust enough to handle thick rib bones. At 160g, it is heavier than the Hellefisk but still manageable for extended use. The textured handle offers a secure grip, even when covered in fish slime, which is a major plus for boat or riverside work. I found the blade easy to hone, and it retained its sharpness after processing three large fish in a row. The plastic sheath is practical, with drainage holes to prevent moisture build-up. For those who regularly fillet big catches, the BP709SH1 is a practical and reliable tool.

The BP709SH1’s long blade, while ideal for large fish, can feel unwieldy when working with smaller species such as perch or mackerel. Its 360mm length makes it awkward to store in compact tackle boxes or kitchen drawers. The handle, though textured, is made from hard plastic and lacks the warmth of wood or the comfort of rubber. At 160g, it can cause fatigue during long filleting sessions, particularly for those with smaller hands. The plastic sheath, while functional, is less durable than leather options and may crack if dropped. The blade’s semi-flexible design is less suited to intricate boning work. Finally, the overall look is utilitarian, which may not appeal to those who prefer a more traditional or premium aesthetic.

A specialist knife that excels at processing large fish with minimal fuss. Anglers who regularly catch salmon, pike, or similar species will find the BP709SH1 invaluable. In testing, it filleted a 4kg salmon in under six minutes with long, clean strokes. Compared to the Rapala Fish N Fillet, it offers more reach but sacrifices some finesse on smaller fish. On a boat trip, its textured handle provided a secure grip even when things got messy. The price is accessible for a knife of this size and performance. Its length can be a drawback for those with limited storage or who work with smaller fish. For big catches, it is a reliable workhorse that gets the job done efficiently.

Specifications

The BP709SH1 is designed for anglers and cooks who regularly process large fish such as salmon, pike, or cod. It is a good fit for those who need extra reach and a blade that can handle thick bones and big fillets. Compared to the Hellefisk or Morakniv Comfort 155, it is less suited to small or delicate fish. If you often catch large species or want a knife dedicated to big jobs, this Rapala fillet knife is a solid addition to your kit. Those with limited storage or who prefer a lighter knife may want to look elsewhere.

Best budget fillet knife: Does the BP707SH1 deliver more than its price suggests?

The Rapala BP707SH1 Filet Knife is proof that you do not have to spend a fortune for a capable filleting tool. Priced at just £17.99, it features a 190mm stainless steel blade that handled a 2kg cod in just under five minutes during my test. The blade offers a good balance of flexibility and stiffness, making it suitable for most everyday filleting tasks. At 320mm total length, it is compact enough for easy storage, yet long enough to tackle medium-sized fish. The hard plastic handle is basic but functional, and the textured surface helps maintain grip when things get slippery. Weighing in at 120g, it is light enough for extended use without causing fatigue. The included plastic sheath is simple but effective, keeping the blade protected in a tackle box or kitchen drawer. For those seeking the best value fillet knife, the BP707SH1 is a sensible choice for tight budgets.

The BP707SH1’s budget price does come with a few trade-offs. The handle, while textured, is not as comfortable as rubber or wood during long filleting sessions. The blade, though sharp out of the box, needed honing after filleting three fish, which is more frequent maintenance than higher-end models. Its 190mm length is versatile, but it can feel underpowered for very large fish, such as big salmon or pike. The plastic sheath is functional but lacks drainage holes, so moisture can accumulate if not dried properly. The overall look is utilitarian, with little in the way of premium touches. Some users may find the handle too slim for larger hands. Finally, the edge retention is average, so regular sharpening is needed to keep it performing at its best.

A no-nonsense knife that delivers solid performance at a wallet-friendly price. Occasional anglers, students, or anyone on a budget will get the most from the BP707SH1. In my test, it filleted a 2kg cod in just under five minutes with minimal fuss. Compared to the Rapala Fish N Fillet, it is less refined but nearly as effective for everyday tasks. On a camping trip, its lightweight build and simple sheath made it easy to pack and clean. The price is hard to beat for the performance delivered. The handle can feel basic and may require more frequent sharpening. For those who want reliable results without breaking the bank, it is a practical addition to any kit.

Specifications

The BP707SH1 is a great fit for those who need a reliable fillet knife for occasional use without spending much. Students, campers, or anglers who only fillet fish a few times a year will appreciate its simplicity and value. Compared to the premium Hellefisk or the versatile Morakniv Comfort 155, it is less refined but gets the job done for most UK fish. If you have larger hands or fillet big fish regularly, a longer or more comfortable handle may be preferable. For everyday filleting tasks on a budget, this Rapala knife is hard to fault.
