The Relentless Knives 9-Inch Curved Fillet Knife is built for anglers who tackle large pelagic species and need a blade capable of processing substantial catches with speed and precision. Designed for fish such as mahi-mahi, tuna, and wahoo, its long, sweeping curved blade makes it possible to cut along an entire side in one smooth pass. Whether you're working aboard a fishing boat or cleaning a trophy catch at the dock, this knife delivers the reach and control needed for demanding fish-processing work.
The 8.8-inch blade is crafted from 6AL-4V aerospace-grade titanium, combining lightweight strength with exceptional corrosion resistance. Weighing just 5.5 ounces, it helps reduce wrist fatigue during extended filleting sessions, while its rust-resistant construction makes it especially well suited to harsh saltwater environments. The curved profile follows the contours of large fish, supporting efficient cuts and helping you recover more usable meat.
Relentless Perpetual Edge Technology sets this knife apart from conventional fillet knives. Its specialized cutting system is engineered to sharpen as it cuts, helping maintain a working edge through repeated use. The micro-serrated cutting edge enhances performance on soft, pliable fish flesh, while the SlickCut anti-friction treatment reduces drag for smoother, more efficient cutting.
The black True Grit handle features glass-reinforced ABS construction with an aggressively textured surface designed to maintain a secure grip when your hands are wet or slippery. Its faceted, non-reflective finish helps prevent heat buildup in direct sunlight, making it a practical choice for long days on deck. A leather sheath is included for convenient storage and protection.
Proudly made in the USA, this rugged fillet knife is backed by a 90-day performance guarantee and a lifetime maintenance warranty.
