10 Best Fish Fillet Knives 2026 in the United States

The HOSHANHO 9-inch fillet knife is designed especially for precision work like filleting fish, but it also handles other meats well. Its blade is made from high-quality Japanese high carbon stainless steel, which keeps the edge sharp for longer and resists rust, so it stays reliable over time. The 9-inch length gives you enough blade to smoothly cut through fish bones and flesh, while its thin and flexible blade makes it easier to follow the natural curves of the fish, resulting in cleaner cuts and less waste.

The handle is made from pakkawood, a sturdy and water-resistant material that offers a comfortable, ergonomic grip to reduce hand fatigue during longer use. Weighing about 1 pound, the knife feels balanced and light enough to control easily but has enough heft to make cutting efficient. One thing to note is that it’s not dishwasher safe, so hand washing is needed to maintain the blade and handle quality.

This knife represents a solid choice for anyone looking for a professional-style fillet knife that combines sharpness, flexibility, and comfort for everyday kitchen use.

The Wüsthof Classic 12-inch Salmon Slicer is a high-quality fillet knife designed specifically for slicing large fish like salmon. Its blade is made of forged high-carbon stainless steel, which is sharp, durable, and resists rust—this means the knife stays sharp longer and handles regular kitchen use without damage. The 12-inch blade length is on the longer side, which helps make smooth, even slices across big fish in a single stroke. The blade has a hollow edge that reduces sticking, making slicing easier and more precise. While the blade is strong and sharp, it is less flexible than some thinner fillet knives, so it’s best suited for slicing rather than intricate filleting or boning. The handle is made from synthetic polypropylene with a full tang and triple rivets, providing a secure, comfortable grip that resists heat and wear over time. At about 3.2 ounces, the knife is lightweight, which helps reduce fatigue during extended use.

Though it is not dishwasher safe, hand washing is recommended to maintain its condition. The knife includes a finger guard for safety and comes with a lifetime warranty, reflecting its long-lasting build and trusted brand heritage. This salmon slicer is an excellent choice for home cooks looking for a reliable, sharp, and well-balanced knife primarily for slicing large fish, although those needing a more flexible fillet knife for delicate tasks might want to consider other options.
