The Big Leuku knife blade is based on Roselli’s traditional Finnish Leuku, a powerful wilderness tool used for generations by reindeer herders, bushcrafters, survivalists, and outdoorsmen.

This large blade is handcrafted from durable premium carbon steel and built for demanding outdoor tasks such as chopping wood, carving, cutting through bone, and general survival use in the wild. It’s trusted for its strength, simplicity, and versatility in forest life.

The blade is available in carbon steel and makes an ideal foundation for anyone who wants to build a heavy-duty knife for rugged outdoor conditions.

Pair it with our curly birch block for knife handles and a stainless steel ferrule to create your own custom wilderness knife – durable, powerful, and made to last.
