10 Best Filleting Knives 2025 in the United States

The Mercer Culinary M23860 Millennia Fillet Knife stands out with its one-piece high-carbon Japanese steel blade, known for retaining sharpness and being easy to maintain. The 8.5-inch blade length makes it suitable for filleting various types of meat, allowing for precise and clean cuts. The blade's narrow design is ideal for removing flesh from bones efficiently.

The handle is made from Santoprene, a material valued for its durability and comfort. Its ergonomic design with textured finger points ensures a non-slip grip, enhancing safety and control during use. The knife features a stamped construction, which can be lighter but may lack the balance and heft that some users prefer.

It is important to note that this knife requires hand washing and cannot be placed in the dishwasher, which might be less convenient for some users. The limited lifetime warranty offers reassurance of quality and durability. This knife would be a strong candidate for those looking for a reliable and well-designed filleting knife, provided they are comfortable with handwashing and do not require a highly flexible blade.

The Mercer Culinary M22807 Millennia fillet knife is a solid choice for anyone needing a dependable tool to fillet meat and fish. Its 7-inch blade, made from high-carbon Japanese steel, is designed to stay sharp longer and is flexible enough to easily separate flesh from bones, which is essential in a fillet knife. The blade's flexibility helps you make delicate cuts without tearing the meat.

The handle is made from Santoprene, a soft, textured material that offers a comfortable, non-slip grip, helping you maintain control even when working with wet hands. The ergonomic design includes finger points for added safety and comfort during extended use. The knife is stamped, meaning the blade is cut from a single sheet of steel, which often makes it lighter and easier to handle but sometimes less robust than forged knives. There is no mention of a full tang, which might affect balance and durability slightly for some users.

It is important to hand wash and dry this knife immediately to keep it in good shape; it is not dishwasher safe and can be damaged if submerged too long. This fillet knife suits both home cooks and professionals who want a sharp, flexible blade with a comfortable handle, though if a heavier, forged knife with a full tang for extra strength is preferred, this model may feel a bit lighter than expected.

The knife is cordless and powered by a lithium-ion battery, with an LED indicator on the handle so you can keep track of battery life easily. The aluminum handle features a non-slip grip and a trigger guard, providing good control and safety during use.

Four removable blades come with the knife, allowing you to swap them out as needed.

The handle is made of aluminum, which is durable but can feel heavier compared to other materials like rubber or plastic, and the overall weight might be a bit much for extended filleting sessions. While the knife is powerful, some users might find the electric function makes it less quiet and a bit harder to handle in tight spaces. This knife is suitable for anglers looking for a heavy-duty, easy-to-use electric option for regular fishing use, especially if they want to speed up the filleting process without losing control.
