The 7 Best Fillet Knives for Saltwater Fish

1. Mercer Culinary Millennia Narrow Fillet KnifeMercer Culinary M23860 Millennia 8-Inch Narrow Fillet Knife, Black

As someone who loves cooking and trying out different culinary tools, I was really excited to get my hands on the Mercer Culinary Millennia Narrow Fillet Knife. Having personally tested the knife, I’m here to share my first-hand experiences, the good and the not-so-good, to help you make an informed decision.

Performance and Handling

From the moment I picked it up, I was taken by the Mercer Culinary knife’s exceptional sharpness. Crafted for professionals, its precision is remarkable, but it doesn’t restrict its usefulness to the realms of professional kitchens alone. My experience deboning a salmon fillet was seamless, as the knife sliced through the fish with little resistance, making it suitable for home kitchens as well.

Despite its professional design and performance, the comfort it offers to the user is remarkable. The knife’s balance and the textured handle ensured a secure grip, reducing the chances of any slips or mishaps. The eight-inch length, which puts the knife in the range of what most would consider a ‘normal’ knife length, provided just the right balance of control and cutting power.

There was a time during my testing when I was preparing a large batch of sashimi, requiring the knife to be both precise and swift. The Mercer Culinary Millennia Knife, with its high-carbon stainless steel blade from Japan, truly shone during this task. The narrow blade, paired with its sharpness, allowed me to cut with excellent accuracy, ensuring perfectly thin and consistent slices of raw fish.

Maintenance and Durability

The durability of the Mercer knife was another aspect that stood out to me. It’s clear that this knife is designed to be a reliable tool in the kitchen, capable of withstanding frequent use without compromise on performance.

Moreover, the maintenance of the knife is a breeze. Post-preparation cleaning involved nothing more than a quick rinse under the tap, thanks to its stain-resistant blade. This high level of convenience only added to the knife’s appeal, saving me precious time during cleanup.


However, there were a couple of areas that could have been better. For instance, the knife doesn’t come with a sheath. This was a bit of a letdown, as it means you’ll need to find a safe storage solution or purchase a sheath separately.

Additionally, while I found the eight-inch length to be optimal, some users might prefer a longer blade for larger fish. This isn’t a fault with the knife, but it’s certainly something to consider based on personal preferences.


  • Exceptional sharpness right out of the box
  • Durable high-carbon stainless steel blade
  • Comfortable and secure grip
  • Stain-resistant and easy to clean
  • Well-balanced design for precision cutting


  • Doesn’t come with a sheath
  • Some users may prefer a longer blade for larger fish


In conclusion, the Mercer Culinary Millennia Narrow Fillet Knife is a remarkable tool that excels in both performance and comfort. Despite a couple of minor drawbacks, its pros far outweigh the cons. Whether you’re a professional cook or an enthusiastic home chef, this knife can prove to be a valuable addition to your kitchen arsenal.

2. Cuda 9-inch Fillet Knife

I had the opportunity to test the Cuda 9-inch Fillet Knife. Here, I present my detailed review, informed by personal experience, examining the positives and a few areas where I found room for improvement.

Quality and Durability

What struck me first about the Cuda knife was the superior quality of its material and construction. Crafted from a combination of bonded alloy and titanium, the knife’s durability was beyond question. A sharp, titanium-made blade is a boon, offering not just reliability but also excellent resistance to staining.

During my time with this knife, I noted that it managed to retain its sharpness remarkably well, making it clear that regular sharpening wouldn’t be necessary. When the time does come for a touch-up, a simple wet stone or a burr would do the job, further enhancing the knife’s user-friendly nature.

Handling and Control

The Cuda 9-inch Fillet Knife offered a full tang, a feature that enhanced the knife’s balance and improved my precision in handling. The knife sat securely in my grip, reducing chances of slips, a quality that shone during my attempt to fillet a large red snapper. The Scale Grip was another feature that provided better control, fostering confidence even while working with large and challenging fish.

Cuda’s triple-layer technology that underpins this knife added to its robustness, making the cutting experience smooth and almost effortless.


Another notable aspect of this knife is its flexibility. Designed for bigger fish, the 9-inch length didn’t limit its versatility. I used it successfully on both saltwater and freshwater fish, and the knife showed no sign of degradation or loss in performance. This resistivity against both water types ensures that this knife would be at home in any kitchen, be it inland or coastal.

The handle size was just right for me – not too small or too large. However, this might be a subjective matter and could vary according to personal preference.


  • Superior grip with the Scale Grip feature
  • Durable and sharp, owing to the bonded alloy and titanium construction
  • Flexible and versatile for both saltwater and freshwater fish
  • Maintains sharpness for a long time
  • Stain-resistant and reliable


  • No sheath included
  • Handle size might be too small for those with a firm grip


After spending some quality time with the Cuda 9-inch Fillet Knife, I can vouch for its strength, precision, and flexibility. Although it doesn’t come with a sheath and the handle size might not suit everyone, its positives significantly outweigh the negatives. Its user-friendly features and reliable performance make it a fantastic choice for anyone seeking a durable and efficient fillet knife, especially those dealing with larger fish.

In this review, I will share my personal insights, the highs, and the lows to provide you with a comprehensive understanding of the product.

Design and Handling

The total length of 15 inches, with a 9-inch blade and a 6-inch handle, seemed initially intimidating but proved to be a boon during usage. The knife features safety guards that protect the blade, a feature I found particularly useful when dealing with fish with hard spines.

One outstanding feature is the handle’s trigger grip, which provides an additional non-slip feature. I recall a time when I had to fillet several fish in quick succession for a family gathering. Despite the repeated use and inevitable wet conditions, the textured handle ensured that the knife stayed firm and secure in my hand, enhancing my control over the cutting process.


While the Bubba Blade Knife showcases many exceptional features, it does require frequent sharpening. In my experience, I found myself needing to sharpen it every few months. However, considering its overall performance and reliability, this extra maintenance step seemed a small compromise.


  • Exceptionally sharp for precise filleting
  • Stain-resistant and rust-resistant for enhanced durability
  • Safety guards to protect the blade
  • Comfortable and secure handle with a trigger grip
  • Reliable and durable construction


  • Requires frequent sharpening

Blade Quality and Versatility

The American Angler Delta Series Fillet Knife stands out due to its remarkable sharpness. Constructed from high-quality German stainless steel, the blade delivered an impressive performance whether I was filleting a small crappie or tackling a sizable tuna.

An appealing aspect of the Delta Series is its wide range of size options, allowing you to select according to your needs. While testing, I found the larger-sized knives particularly effective for saltwater fish, which tend to be larger.

Durability and Maintenance

The knife’s durability is undeniable, promising a long-lasting presence in your kitchen tools. Moreover, its affordability makes it a highly attractive choice for both amateur home cooks and professional chefs.

Notably, the knife’s sharpness sustains over time, alleviating the need for frequent sharpening. This low-maintenance quality gives the American Angler Delta Series an edge in practicality.

5. Rapala 4 Soft Grip Fillet KnifeRapala4 Soft Grip Fillet / Single Stage Sharpener / Sheath, 4-Inch

Having tested a plethora of kitchen knives over the years, I recently set my sights on the Rapala 4 Soft Grip Fillet Knife. I was intrigued by its features, and I’m pleased to share my personal experience, detailing its strengths and areas for improvement.

Blade Quality and Handling

The standout feature of the Rapala 4 is undoubtedly its German stainless steel blade. Known for its superior quality, the steel ensured the blade’s exceptional sharpness. This sharpness was put to the test when I had to fillet some quite tough saltwater fish – the knife handled it with ease, cutting through smoothly.

The soft grip handle, designed to prevent slipping, was a major plus. The grip texture provided a firm hold, enhancing the safety and precision of each cut. However, for individuals with larger hands, the handle size might pose a slight inconvenience, as it seemed on the smaller side.

Extras: Sheath and Sharpener

One of the things I appreciated about this knife was the inclusion of a sheath and a sharpener. The sheath was a valuable addition, offering both safety and portability. I recall a fishing trip where the sheath proved incredibly useful, allowing me to transport the knife safely and use it on the spot.

As for the sharpener, while it’s a thoughtful inclusion, its effectiveness was somewhat questionable. During my use, I found it didn’t quite bring the knife to the level of sharpness I desired. You might want to consider investing in a more robust sharpener for optimal results.


  • Exceptionally sharp blade made from high-quality German stainless steel
  • Non-slip grip for secure handling

The knife’s sharpness, comfortable grip, and added portability with the sheath make it a commendable choice for any culinary enthusiast or professional.

For those in need of a reliable fillet knife, especially for dealing with tougher, saltwater fish, the Rapala 4 Soft Grip Fillet Knife is a worthy contender.

6. Bubba Blade 9 inch Serrated Flex Fillet KnifeBubba 9 Inch Tapered Flex Fillet Knife with Non-Slip Grip Handle, Full Tang High Carbon Stainless Steel Titanium Coated Non-Stick Blade, Lanyard Hole and Synthetic Sheath for Fishing

After spending some quality time in the kitchen with the Bubba Blade 9 Inch Serrated Flex Fillet Knife, I feel compelled to share my personal experience. This blade not only outperformed my expectations but also introduced me to a few unique features that make it a standout in its class.

Construction and Build

Mirroring its cousin, this Bubba Blade fillet knife boasts a 9-inch blade attached to a 6-inch handle, rendering an overall length of 15 inches. A standout feature is the inclusion of safety guards on the blade, specifically designed to protect against potential damage from fish spines. This precautionary measure proved useful during a particularly challenging filleting session involving a large, spine-dense fish.

Moreover, the handle of this knife incorporates a trigger grip which effectively enhances the non-slip attribute, providing an excellent hold even when maneuvering complex cuts.

A Handle for Comfort

What sets this knife apart, however, is its thoughtful design for those who suffer from arthritis and gout. The handle, crafted from a comfortable rubber and boasting an ergonomic design, was surprisingly comfortable even during long hours of use. I tested this knife during an extensive cooking session that involved filleting numerous fish, and it remained comfortable throughout.

Blade Quality and Accessory

The blade, being stain and rust-resistant, maintained its appearance and effectiveness even after rigorous use. The serrated edge was especially useful when filleting larger fish, ensuring smooth, precise cuts each time.

The inclusion of a sheath is a thoughtful addition, though its quality may be a bit lacking for some users. While it does provide protection and portability, its overall build quality is somewhat inferior to the knife’s.

  • Delivers very smooth, precise cuts
  • Ideal for individuals with arthritis and gout, thanks to the ergonomic handle design
  • Blade is stain and rust-resistant, maintaining longevity

My personal experience with this knife was overwhelmingly positive, and I recommend it to anyone seeking a reliable, user-friendly fillet knife.

I’ve run this blade through a battery of tests, filleting everything from snapper to bass, and it’s held up exceptionally well.
