The Marttiini Martef Filleting Knife 19 (Model 836014T) is a fixed-blade fishing filleting knife engineered for processing and filleting whole fish, skinning fillets, and trimming cuts. Featuring a 19 cm moderately flexible stainless chromium steel blade, the tool is coated in Marttiini's proprietary Martef fluoropolymer layer, which reduces surface friction to near-zero for fluid passes through flesh while shielding the underlying steel from saltwater and fish acid corrosion. Designed for marine and camp environments, the knife weighs 85 g and features a textured rubber handle with an integrated finger guard to maintain grip when handling wet or slippery catches. It comes supplied with a black leather sheath featuring an integrated belt loop, bringing the total carried weight to approximately 130 g.

Key Features

• Martef Low-Friction Coating: Fluoropolymer and titanium-based blade coating minimises drag when slicing through fish flesh and provides enhanced surface resistance against corrosion from marine saltwater and organic acids.
• Moderately Flexible Chromium Steel: Combines edge retention with controlled lateral flex, enabling precise tracking along fish backbones and skinning cuts.
• Textured Safety Grip: Blue rubberised handle with an integrated forward finger guard prevents forward hand slippage when wet, slimy, or handling bait residues.
• Protective Carry Sheath: Supplied with a tailored black leather sheath with belt loop (Model 836014T configuration) for secure transport and storage.

Who is the Marttiini Martef Filleting Knife 19 for?

• Anglers processing fish weighing 2 kg to 3 kg — requires the 19 cm blade length to clear mid-sized carcasses and skin fillets in smooth, uninterrupted passes with this specialised fishing filleting knife.
• Campers and fishers requiring saltwater-resistant food preparation tools — benefits from an 85 g lightweight knife footprint and a low-friction Martef coating that prevents fish acids and marine water from corroding the blade during multi-day field use.

Less suitable for: Targeting small panfish or baitfish under 2 kg where the 19 cm blade compromises control (a shorter 15 cm filleting knife variant offers better tip precision), or pelagic and large reef species exceeding 3 to 4 kg where single-pass processing requires a longer 23 cm filleting knife.
