10 Best Fish Fillet Knife 2025 in the United States

The Mercer Culinary Millennia fillet knife features a narrow 8.5-inch high-carbon steel blade that holds a sharp edge well, ideal for precise fish filleting. Its flexible blade allows for easy separation of flesh from bones, making it particularly useful for delicate filleting tasks. The handle is crafted from Santoprene, a soft yet durable material, with an ergonomic design and textured finger points to provide a secure, non-slip grip—important when working with slippery fish.

Weighing just 4.6 ounces, the knife is light and easy to handle during detailed cutting. It requires hand washing and immediate drying to maintain its quality, as it is not dishwasher safe. The stamped construction offers a balance of durability and affordability, making it a practical choice for home cooks who want a professional-style fillet knife without a high price tag.

This Mercer knife balances sharpness, control, and comfort effectively. It is well-suited for those willing to provide a bit of extra care in maintenance but may be less ideal for users who prefer low-maintenance cleaning or need a stiffer blade for tougher fish.

The Dalstrong 7-inch Fillet Knife from the Gladiator Series Elite is designed specifically for filleting fish and other meats, making it a strong choice for both home cooks and professionals who need precision and ease in their cutting tasks. Its blade is made from high-carbon German steel, known for holding a sharp edge well, and is carefully hand-polished to be razor-sharp, allowing smooth, clean cuts along bones without tearing the flesh. The blade's flexibility is just right to follow the curves of fish and meat, which helps separate meat efficiently. At 7 inches, the blade is long enough to handle larger fillets and reduces wrist strain by allowing longer slicing motions.

The handle is made from black G10 Garolite, a durable and sanitary material that is triple-riveted for strength and designed to fit comfortably in your hand, giving you good control and reducing fatigue. Weighing only 6 ounces, the knife feels balanced and agile, not heavy. It’s also NSF certified, meaning it meets strict sanitation standards, which is great for kitchen safety. One downside is that it’s not dishwasher safe, so it requires hand washing to maintain its quality.

While it’s highly praised for sharpness and build, users should take care with the flexible blade as it can be less suited for tougher cutting tasks. This knife serves as a reliable, well-crafted tool for anyone looking to fillet fish or bone meat with precision and ease.

The Bubba Li-Ion Cordless Electric Fillet Knife is a solid choice for fishing enthusiasts who want a convenient and efficient filleting tool. Its cordless design, powered by a rechargeable battery, offers great freedom of movement compared to corded models or manual knives. The blade is 7 inches long and made from stainless steel coated with titanium nitride, which helps reduce sticking and improves durability. The blade’s V-grind and Wharncliffe shape are designed for precise, clean cuts, making filleting easier, especially on small or medium-sized fish. The handle is made of stainless steel but covered with a rubbery, non-slip grip to provide secure handling even when your hands are wet. It also has a trigger guard to prevent accidental activation, adding a safety layer.

At about 1.11 pounds, it’s on the heavier side for a fillet knife, so it may feel a bit bulky during extended use. The knife features removable blades for easier cleaning and storage, with a dedicated case included, which is quite handy. There is an LED battery life indicator on the handle, helping you avoid unexpected power loss while working. However, hand washing is necessary to maintain the knife properly, as it’s not dishwasher safe. The product comes with a one-year limited warranty, giving some peace of mind.

If you want a powerful, easy-to-control electric fillet knife that reduces effort and speeds up fish cleaning, this model fits well, especially for casual to moderate fishing tasks. For those who prefer a lighter, more traditional feel or require a budget option, there may be simpler knives to consider.
