10 Best Fish Fillet Knife 2026 in the United States

The HOSHANHO Fillet Knife stands out for its high carbon steel blade made from Japanese AUS-10 stainless steel, ensuring durability and superior sharpness. The 7-inch blade length is ideal for filleting fish and other types of meat, providing precision and less wastage while cutting. The blade's flexibility allows it to adapt to the contours of fish, making it easier to maneuver and control, which enhances the efficiency of filleting tasks.

At the same time, the knife is relatively lightweight at 10.6 ounces, contributing to its ease of use. The ergonomic handle made from pakkawood not only offers a comfortable grip but also ensures longevity due to its resistance to corrosion and abrasion. The knife's multifunctionality is a notable plus, as it can be used for various kitchen tasks beyond filleting fish, such as cutting poultry and other meats. However, it is not dishwasher safe, which means it requires careful hand washing to maintain its edge and finish.

Additionally, its high-ranking position suggests that it is well-received among users. While it is primarily designed for professional use, home cooks who frequently prepare fish and meat will also find it a valuable addition to their kitchen tools.

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 WORKPRO 12V Cordless Electric Fillet Knife is a solid choice for fishing enthusiasts who want an easy-to-use, portable solution for filleting fish. It comes with two razor-sharp stainless steel blades—an 8-inch flexible one and a 10-inch stiffer blade—covering a good range of fish types from small to large. The blades are durable and serrated, which helps in precise cutting. The rubber-coated handle offers a comfortable, non-slip grip, making it safe to use even when wet.

Although the product weight is around 4.8 pounds including batteries and case, the knife itself is lightweight (about 1 pound without blades and battery), so handling during filleting remains manageable. The cordless design, powered by two rechargeable lithium-ion batteries, allows about an hour of continuous use per battery and charges quickly within an hour, giving you nearly uninterrupted filleting time. A safety lock on the battery pack adds extra security during use. The included hard storage case is convenient for keeping everything organized and protected when traveling.

One consideration is that the slightly heavier overall kit might be a bit cumbersome for some to carry around, and the blade length is fixed with only two options, which may not suit very small or very large fish perfectly. The knife requires hand washing to maintain blade quality. If you want a reliable cordless fillet knife with good battery life, solid blades, and a comfortable grip, this model fits well, especially for casual to moderate fishing trips.
