The most advanced and innovative mountaineering ice axe out there. The Corsa Nanotech uses the same 7075-T6 aluminum alloy as the hyperlight Corsa, but includes Sandvik Nanoflex® steel reinforcements on the pick and spike, making it more suitable for alpine ascents where mixed climbing and cutting steps are likely to be on the cards. The steel components significantly increase the durability and strength of these critical points without increasing the weight of the axe unreasonably. Additionally, the Corsa Nanotech has an aggressive single-curve shaft that brings better clearance without limiting walking or plunging performance. Can be fit with either the sliding leash (1305) for mountaineering or the Alpina leash (1304) for alpine climbing
