10 Best Fishing Knives 2026 in the United States

The Mercer Culinary M23010 Millennia is a well-made fishing knife designed primarily for slicing fish, like salmon, with precision. Its 10.3-inch blade is crafted from high-carbon Japanese steel, known for holding a sharp edge and being easier to maintain. The blade is thin and flexible, which helps in making clean, even cuts through delicate fish without tearing the flesh.

The handle is made of Santoprene, a textured material that provides a comfortable, non-slip grip—even when your hands are wet, which adds safety and control during use. While the blade has a plain edge rather than serrated, this suits the slicing task well. One downside is that the knife is not dishwasher safe, so it requires hand washing and careful drying to keep it in good condition over time. It doesn’t come with a sheath, so you’ll want to store it safely to protect the blade and your fingers.

This knife is a solid choice if you're looking for a reliable, sharp slicer for fish preparation that balances quality and ease of use, especially for home cooks or those less experienced with professional knives.

The blade is stamped, which generally means it’s lighter and more flexible than forged knives, making it suitable for delicate cutting around bones and skin. The handle is made from Santoprene, a soft, textured material that offers a secure, non-slip grip even when wet, adding comfort and safety during use.

While it doesn’t come with a sheath, its ergonomic design and lightweight build make it a good choice for home cooks or those who want a reliable knife for fish and meat preparation.

The blade has a plain edge, which is typical and effective for clean slicing.

The handle is made from Santoprene, a material that offers a comfortable, non-slip grip thanks to textured finger points, making it safer and easier to handle when wet or slippery.
