The Marttiini Martef Filleting Knife 15 (Model 826014T) is a dedicated flexible fish filleting knife engineered for cleaning, skinning, and precision slicing. Manufactured in Finland, this manual hand tool combines a stainless steel blade with Marttiini's proprietary Martef non-stick coating. The low-friction surface reduces cutting drag to nearly zero across fish flesh and protects the underlying steel against corrosion. Designed with a total length of 27 cm, the knife features an ergonomic blue textured rubber handle with an integrated molded finger guard to maintain physical grip in wet or slimy conditions. It comes supplied with a black leather belt sheath designed for secure hip carry during bank fishing and field processing.

Key Features

• Martef Non-Stick Blade Coating: The proprietary surface finish eliminates meat friction and prevents fillets from sticking to the blade during slicing, while delivering additional protection against salt- and freshwater corrosion.
• High-Traction Safety Handle: Built with blue textured rubber, a plastic ferrule, and an integrated finger guard to ensure non-slip retention when hands are wet or covered in fish slime.
• Purpose-Built Flexible Profile: The flexible 15 cm stainless steel blade follows bone contours and skin lines closely for clean meat separation.
• Leather Belt Sheath: Supplied with a fitted black leather sheath designed for safe transport and immediate access on a belt.

Who is the Marttiini Martef Filleting Knife 15 for?

• Recreational freshwater and saltwater anglers — processes catch weighing around 1 kg using a 15 cm flexible stainless steel blade sized specifically for single-pass rib clearing on smaller to medium fish.
• Campers and camp cooks — handles precision outdoor kitchen slicing and food preparation using a 27 cm total length flexible filleting knife that features a non-stick coating to stop food binding to the blade face.

Less suitable for: Processing fish exceeding 1.5 to 2 kg or wide-bodied species with deep rib structures; for these catches, a longer filleting knife featuring a 19 cm or 23 cm blade is better suited to complete full-depth fillet passes without binding.
