The Grivel Ghost Evo is a technical mountaineering axe that won't weigh you down. Coming in at a mere 11 ounces, it's designed to thrive on the steep, technical routes that you dream about every night. The carbon steel blade and spike are not only strong and durable, but also contribute to keeping the overall weight of the axe down. A slight curve in the upper part of the shaft provides a more efficient swing for better pick placement, and also makes anchoring easy on a wide variety of terrain.
