The Air Tech Evolution is one of Grivel's classics. It has a chromium steel blade hot forged in the Aosta Valley in Italy, which makes it very resistant to wear along the long side and with a better momentum to place its bevelled point in the ice. The G-Bone handle with a slight bend and the slight curve under the blade of theAir tech Evolution are optimal to improve the grip and anchorage in snow or ice. In addition, the lower part of the handle is covered with rubber for a better grip.It has safety clips to attach the ice axe to the harness to prevent it from getting lost during your climbs. This also allows you to change the hand of the ice axe according to your situation and needs.
