Comparison With Another Fillet Knife

Let us compare the Mercer Culinary Genesis Fillet Knife side by side with the nine-inch Kershaw Curved Fillet Knife. There is a two-inch size difference between the blades, and the two fillet knives are ideal for filleting medium-sized to larger fish.

The Mercer uses high-quality German stainless steel while the Kershaw Curved Fillet Knife utilizes a high-performing 420J2 stainless steel. They have different handle materials, with the Mercer having a Santoprene handle and the Kershaw boasting a glass-filled nylon handle.

When it comes to the handle’s durability, we prefer Mercer’s handle because the material is known to withstand excessive temperatures  and pressure. More than that, while the Mercer doesn’t come with a protective sheath, the Kershaw has a plastic, slotted cover.

In terms of flexibility, we find the Kershaw to be more rigid and has less flex, compared to the moderately flexible Mercer Fillet Knife. Flexibility is one of the key features you must look for in a fillet knife as it affects the maneuverability and ease of use.

In the end, we have concluded that the Mercer Fillet Knife is the complete package when it comes to blade length, flexibility, and overall build and performance.


The Mercer Culinary Genesis Fillet Knife has almost everything we are looking of in a fillet knife. Its seven-inch blade is just right for filleting medium to large fish, plus it has the flex that is needed to execute clean fillet cuts that are close to the skin. No meat wasted with a knife this sharp and flexible.

The blade is surprisingly sharp, even if it’s thicker than most fillet knives. It stays sharp, and when it needs refreshing, a few runs against the steel or a knife sharpener will make the blade as sharp as new again.

The blade runs through the handle, giving you a good grip and balance that makes any cutting and slicing technique easy. The only issue about the design is the short handle, which makes the knife not fit for use if your hands are rather big. Otherwise, you may select another bigger knife from the same Mercer Culinary Genesis line.

Also, while it does not come with a protective cover, you can always buy one that can easily match the size of this seven-inch knife. The overall look is great and makes it an appealing addition to any kitchen. All in all, with its sharpness, quality, and elegant appearance, the Mercer Culinary Genesis Fillet Knife is a good choice for a professional-grade fillet knife.
