The Marttiini MFK Curly Birch is a folding knife built for everyday carry and general use — the kind of knife that earns a permanent place in a pocket or on a belt. It brings Finnish tradition to a practical, versatile format that works as well around camp as it does handling everyday cutting tasks.

The 3.15-inch blade is made from Japanese stainless steel with a satin finish — a steel known for holding a clean, reliable edge while resisting corrosion. At just over three inches, the blade sits in a practical everyday carry length — capable enough for trail tasks, food prep, and general cutting without being cumbersome to carry.

The handle scales are Finnish curly birch, whose swirling, unpredictable grain makes each knife genuinely one of a kind. The birch is set into a brushed stainless steel frame that gives the knife a solid, substantial feel in hand despite its compact folded length. A liner lock — a spring-loaded internal mechanism that locks the blade firmly open during use and releases with a deliberate push — keeps the blade safely in place when you need it. An integrated belt clip on the handle makes it easy to carry clipped to a pocket or belt, ready when you reach for it.
