10 Best Filleting Knives 2026 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 Dalstrong Valhalla Ravenstone 3-piece set is a versatile knife collection ideal for those who need slicing, filleting, and heavy-duty cutting tools in one package. The set includes a long 12-inch slicer, a flexible 6-inch fillet knife, and a sturdy Venator knife that handles tougher tasks. Each blade is made from high-quality 9CR18MOV stainless steel, enhanced with a black titanium coating for better edge retention and resistance to rust. The blades are sharpened very finely, making them precise for delicate cuts like fish filleting or slicing brisket.

The handles combine stabilized wood and resin, offering an attractive, ergonomic grip that’s reinforced for durability and comfort during extended use. The Venator knife’s design adds extra grip features for better control. One notable strength is that each knife comes with a leather sheath, making storage and portability safer. However, the knives are not dishwasher safe, so cleaning by hand is necessary.

Weighing about 4.5 pounds total, the set might feel bulky for some users. For those seeking a stylish, durable, and sharp filleting knife set that covers a wide range of kitchen cutting needs and don’t mind hand washing, this Dalstrong set is a solid choice backed by a 70-day return policy and lifetime warranty.
