Best Fillet Knives Reviews

Berkley Floating FilletKnife

Berkley® Floating Fillet Knife-6in
  • 8 in stainless steel blade resists corrosion
    Standard size fits most electric knives

Berkley Floating FilletKnife ranks somewhat lower. They’re the less popular option in general. Fishing combines water and the outdoors. While electric knives are primarily useful indoors. But if one is only getting fish from the store then this is a great option. And the host of adapters it ships with can power it from standard car adapters. The variety of adapters are also why it makes the list.

Unlike many fillet knives, it is quite usable on camping trips. To a limited extent, to be sure. But it will still be functional. And it can even switch between six and eight inch blades.

Finally, the grip has been designed with moisture in mind. One shouldn’t have to worry about vibration pushing it out of one’s hand.

  • Overall Length: 17 Inches.
  • Blade Length: 8 Inches.
  • Blade Steel: Stainless Steel.
  • Blade Thickness: Detachable.
  • Weight: N/A (variable components).

Victorinox Cutlery Fillet Knife is an interesting knife due to reputation. It’s usually sold as a kitchen knife. But branding alone shouldn’t determine ranking. It’s in the list of best fillet knives because of performance.

It features an ergonomically designed polypropylene handle. Holding it one will instantly see that despite marketing, it’s not just a kitchen knife. It’s perfectly suited to both indoor and outdoor use.

Additionally, the overall sweep of the blade is low enough to make boning a simple matter. Which also raises utility for outdoor use. Finally, the blade’s overall carbon content keeps it sharp even after a large number of sharpening attempts.

It’s one of the best fillet knives once one gets past the single setting reputation. After one actually tries it the real world use becomes a lot more clear.

  • Overall Length: 13 1/4th Inches.
  • Blade Length: 7.9 Inches.
  • Blade Steel: High Carbon.
  • Blade Thickness: 1/16th.

The Steelheader Suregrip is another knife that ranks lower simply due to specialty use. People usually find themselves surprised by the knife’s small size. This small size is a big benefit under certain conditions though.

It ranks among best fillet knives for precision work. One can almost see it as much of a scalpel as a knife. The small overall size is by design. Again, it’s designed for a small size for the same reasons behind a scalpel’s design.

Combined with etched finger grips it’s perfect for precise work. As one becomes use to the form factor, overall speed is likely to increase as well. This places it among the best fillet knives for quick and precise cuts.

The Wusthof Classic Fillet Knife showcases quality right from the start. The blade itself has been stamped to showcase an artistic design. And the included sheath is as much a visual showcase as a functional accessory.

But for all the beauty of the knife. It holds up under pressure. The high quality german steel holds up to long term use with little danger of corrosion. But the traditional design is also one of the larger issues.

It’s older style of design means that it needs sharpening more often than many newer designs. How this knife ranks among the best fillet knives depends on one’s viewpoint. It might rank higher for people who value elegance and tradition. While ranking lower for someone who values utility.

  • Overall Length: 11 Inches.
  • Blade Length: 7 Inches.
  • Blade Steel: X50CrMoV15.

The Morakniv Fishing Comfort Fillet Knife should rank among the best for sheer utility. Unlike many of the others, it’s not trying to aim for artistic perfection. The focus on utility is obvious in most design choices.

For example, unlike some of the other knives it doesn’t ship with a leather sheath. Instead it uses a functional, but visually unimpressive, plastic sheath. But if one only cares about utility than this knife has a lot to offer.

The Sandvik blade can hold up under an impressive amount of strain. And one can choose between a three and six inch design. As such it fits both rough and detailed tasks.

The hand ground blade also matches up quite well with these types of larger fish. It starts out incredibly sharp and can maintain that edge over time. In general one should consider it as a knife to use under harsh conditions.

The notched finger grooves continue that trend. It ensures one can keep a firm grip even when working with larger masses. People can use it both indoors and outdoors. But the size and endurance make it especially well suited to use when camping.

Bark River Kalahari Sportsman

The Bark River Kalahari Sportsman earns top ranking due to overall excellence. Many of the other candidates for best fillet knives show heavily specialization. The Kalahari Sportsman, instead, does almost everything perfectly.

The edge has a high quality convex grind. And it starts sharp enough to hold up against a standard straight razor. But even more remarkably, it maintains that sharpness to an incredible degree. It’s even stamped to highlight the high quality design.

The only minor issue comes from lack of accessories. Higher quality blades like this usually come with a sheath. But while it has a lanyard hole, there’s no actual sheath.

  • Blade Length: 6.75 Inches.
  • Blade Steel: S35VN.
