Frequently Bought Together
The saltwater fillet knife (N-Boost™ Series) from Gomexus is the new performance benchmark for charter captains, commercial fish processors, and offshore anglers. Forged with groundbreaking N-Boost™ molecular nitrogen-infused steel and honored with the 2026 iF Design Award, this elite blade delivers 1.85X edge retention over Sandvik 14C28N, 168-hour certified saltwater rust immunity with zero coatings to flake, and a precision-flex blade profile that hugs fish spines to maximize meat yield.
Key Features & Performance Upgrades
- N-Boost™ Molecular Nitrogen Steel: As a game-changing saltwater fillet knife, the nitrogen-boosted atomic lattice delivers 185% edge retention and 125% out-of-the-box sharpness, effortlessly slicing through thick scales and cartilage on over 100+ consecutive fish without rolling an edge.
- Zero-Coating Chemical Integrity: Unlike painted blades that chip harmful flakes into your fillets, our inherent nitrogen steel provides complete corrosion resistance throughout the entire metal core, easily passing 168 hours of continuous saltwater fog testing.
- Engineered Spine-Hugging Flex: Precision-tapered blade elasticity follows the exact contours of fish ribs and backbone, gliding through skin and tough pin bones without binding or snapping.
- Ergonomic CNC-G10 Anti-Slip Grip: Heavy-duty machined G10 fiberglass scales provide a non-slip, zero-mess grip when soaked with water, blood, or slime, supporting standard power grips, pinch grips for delicate work, and finger-rest leverage cuts.
- Reinforced Protective Leather Sheath: Comes complete with a genuine heavy-grain leather sheath with reinforced stitching and belt loop for safe dockside transport and rapid access.

This GOMEXUS fillet knife is definitely worth the price. It is sharp out of the box and is ready to fillet any fish you put on the table. It functions as intended, making it easy for me to be able to make sharp cuts without feeling like I have to tug the fish very hard. It’s great quality and the blade is made of great steel. It works well with both saltwater and freshwater fish. I have not had any issues with it rusting while using it in saltwater, especially because I do take great care of it by giving it a good wash. This can easily be sharpened, but I have used it for a few times and have not had to sharpen it once.
Nice it
very good
