The Marttiini Martef Filleting Knife 23 is built for large fish — the kind of catch that demands a long, confident blade and a grip that holds firm when conditions are anything but ideal. At 9 inches, this is a serious filleting knife designed to move through the dense flesh of large saltwater fish like tuna and salmon in long, clean strokes that a shorter blade simply cannot achieve.

The blade is stainless steel with Marttiini's proprietary Martef coating — a non-stick surface treatment that reduces friction to almost nothing as the blade moves through flesh. The result is cleaner, smoother cuts with less resistance and less waste. The coating also protects the blade against corrosion, and makes cleanup after a long day on the water quick and easy.

The handle is blue rubber with a pronounced finger guard — designed specifically for wet, slippery conditions where grip security is non-negotiable. The textured surface keeps the knife firmly in hand through an entire cleaning session, whether you're on a boat deck, a dock, or a riverside cleaning table.

The knife comes with a black leather sheath embossed with the Marttiini fish logo — built to protect the blade during transport and storage. Hand wash recommended.
