The Marttiini Tundra is a purpose-built bushcraft knife — designed from the ground up for demanding outdoor work rather than display. This is the knife you reach for when the task is real: splitting kindling, carving tent stakes, clearing brush, or handling whatever the wilderness puts in front of you.

The 4.33-inch blade is built from high-strength stainless steel hardened to HRC 58 — significantly harder than standard stainless, meaning it holds a sharp edge through extended heavy use while still resisting corrosion. The blade and full tang are both 3.5mm thick, giving the Tundra the backbone to handle demanding tasks without flex or fatigue. Full tang construction means the steel runs the entire length of the knife from blade tip through the handle — the strongest possible configuration for a working knife.

The handle is shaped from waxed Finnish curly birch, whose natural grain variation makes each knife unique. The wax treatment protects the wood against moisture and keeps the grip secure even in wet conditions. Two steel rivets fasten the handle scales firmly to the tang, adding durability where it counts.

The sturdy dark brown leather sheath is reinforced with rivets and finished with bold red stitching — a modern detail that gives the Tundra a distinctive look on the belt. A confident knife for confident use, and a serious gift for anyone who spends real time outdoors.
