Knife - Essential Tool for Camping, Outdoor Adventure and collection

The Böker Plus Extension Knife is a modern hunting knife that blends the tradition of the “extendable knife” with cutting-edge materials and finishes. Designed for those who demand reliability, power, and versatility in the field, it features a thick and solid D2 steel blade, a G10 handle with steel liners, and a custom-fitted Kydex sheath. This knife ensures durability, precision, and comfort even in the most demanding outdoor tasks.

Its solid locking system, using a large transverse pin, guarantees stability in both open and closed positions. The handle’s historical design recalls the double-T baselards of the 15th century, giving the knife a unique and iconic look. Ideal for hunting, camping, or discerning collectors, the Böker Extension Knife stands out for its outstanding performance and craftsmanship.
