The Marttiini Järvi Annual Knife 2026 (Model 552026C) is a dedicated fish filleting knife manufactured in Finland. Designed specifically for cleaning, skinning, and preparing both freshwater and saltwater catch, it features a long, flexible, polished stainless steel blade measuring between 18.4 cm and 19.0 cm with a slim 1.3 mm spine. The knife pairs traditional Nordic styling—including a dark, heat-treated curly birch handle and stainless steel fittings—with a dedicated leather belt sheath for field carry. Weighing just 80 g to 85 g knife-only (approximately 160 g total with the sheath), it provides low-fatigue control during delicate processing along fish skin and bone.

Key Features

• Flexible Filleting Geometry: The 1.3 mm thick stainless steel blade delivers controlled flex to smoothly follow the contours of fish skeletons and skin during preparation.
• Annual Edition Craftsmanship: Features reflective laser-engraved aquatic motifs on the polished blade and bolster, alongside individually serialized markings designating it as a limited 2026 production run.
• Ergonomic Nordic Handle: Constructed from dark, heat-treated curly birch with a stainless steel bolster and nickel butt cap fittings for a secure, balanced grip in wet conditions.
• Protective Field Sheath: Includes a genuine black chrome-tanned leather sheath accented with blue foil lake-pattern stamping and an integrated belt loop for secure hip carry.

Who is the Marttiini Järvi Annual Knife 2026 for?

• Anglers processing freshwater and saltwater fish — requires the 1.3 mm thin, flexible stainless steel spine on this filleting knife to trace closely along the rib cages and skin of species like trout, redfin, flathead, and salmonids without tearing delicate flesh.
• Nordic knife collectors — values the serialized production markings and laser-engraved aquatic motifs on an annual edition fixed blade measuring 29.8 cm to 30.0 cm in overall length with heat-treated curly birch fittings.
• Lakeside camp cooks — benefits from an ultra-lightweight 80 g to 85 g filleting knife that carries comfortably on a belt loop for lakeside fish preparation and fine food slicing.

Less suitable for: Heavy camp craft or wood processing requiring batoning or chopping, which requires a heavy scandi-grind outdoor knife with a 3.0+ mm blade stock, or breaking through heavy bone and cartilage on large game or offshore pelagics, which requires a rigid bone saw or heavy-duty hunting drop-point.
