The horn supports the hand, protecting it from violent blows against the wall. It also is a safe and balanced suport for the ice axe against ice. The Horn can be detached when a completely free spike is required. The Horn can be fitted on all Grivel's ice axes, even on the earlier models that have a spike with a clip hole. The Horn is a must have for leashless climbing.
WARNING: The Horn has been designed only as a support for the climbers hand. It must never be used for maneuvers with ropes.
