10 Best Fillet Knives 2026 in the United States

The WORKPRO 12V Cordless Electric Fillet Knife is a well-thought-out tool designed with fishing enthusiasts in mind. It comes with two razor-sharp stainless steel blades—an 8-inch flexible blade and a 10-inch stiffer one—making it versatile enough to handle different types of fish, from delicate to firmer varieties. The blades have a serrated, V-grind edge which helps in making precise cuts with less effort. The knife’s handle is metal with a rubberized, non-slip grip, ensuring comfortable and secure handling even when wet, which is important for safety and control during filleting.

Being cordless and lightweight (about 1 lb without blades and battery), it’s easy to maneuver, reducing hand fatigue over longer use. The inclusion of two rechargeable lithium-ion batteries and a quick charger means you can keep working without long interruptions, which is handy on fishing trips. A safety lock adds an extra layer of protection during use and transport. The set also includes a sturdy carrying case, great for keeping everything organized and protected.

One consideration is that since the handle is metal, it might feel cold or slippery if the rubber coating wears out over time. Also, because the blades are reciprocating (moving back and forth), some users might find it less precise than traditional fixed blades, especially for very intricate filleting. Hand washing is required to maintain the knife’s longevity, so it’s not dishwasher-safe. For those looking for a fast, reliable, and cordless option primarily for fishing, this knife provides strong value with its thoughtful design and convenient features.

The Mercer Culinary M22807 Millennia is a 7-inch fillet knife designed for precision and ease when removing flesh from bones. Its blade is made from high-carbon Japanese steel, which helps it stay sharp longer and makes edge maintenance easier. The 7-inch blade length is a good balance—long enough for flexibility yet manageable for detailed filleting work. This knife features a flexible blade, ideal for following the curves of fish or meat for cleaner cuts.

The handle is made of Santoprene, a soft but durable material that offers a comfortable grip. It has textured finger points to reduce slipping, adding safety and control, especially when working with wet hands. This ergonomic design benefits both home cooks and professionals who spend time filleting. The blade edge is plain, meaning it’s smooth and sharp, perfect for delicate slicing without tearing the meat. The manufacturer advises hand washing to keep its quality intact and avoid dishwasher use.

The blade is stamped rather than forged, which may not provide the same weight or durability as forged blades but keeps the knife lighter and easier to handle. While excellent for filleting, it is not designed for heavier chopping or cutting through bones. This Mercer Culinary fillet knife suits anyone looking for a reliable, sharp, and comfortable tool for filleting tasks, with its flexibility, good blade length, and secure handle design making it effective for both beginners and experienced users.

The Mercer Culinary M23860 Millennia 8.5-Inch Narrow Fillet Knife stands out primarily for its quality construction and ergonomic design. The blade is made from high-carbon Japanese steel, which ensures long-lasting sharpness and makes it easier to maintain. This is excellent for those who need a reliable knife that stays sharp and is easy to care for. The 8.5-inch blade length is suitable for filleting various types of meat, making it a versatile addition to your kitchen tools.

The blade is narrow and has a plain edge, which is ideal for precise cuts and removing flesh from bones efficiently. The handle is made from Santoprene and features textured finger points, providing a non-slip grip that enhances safety and comfort during use. The ergonomic design also ensures durability, making it well-suited for both professional chefs and home cooking enthusiasts.

On the downside, the knife is not dishwasher safe, which means it requires careful hand washing to maintain its performance and longevity. Additionally, while the knife is designed to be durable, the stamped construction might not be as robust as forged knives. However, this is a minor drawback considering the knife's performance and price point. It also comes with a limited lifetime warranty, adding an extra layer of assurance for buyers. In summary, the Mercer Culinary M23860 Millennia Fillet Knife is a solid choice for anyone in need of a dependable, sharp, and comfortably designed fillet knife. Its high-carbon steel blade and ergonomic handle make it well-suited for both professional and home kitchens, though it requires proper hand washing to maintain its quality.
