An ice tool with a patented changing system that requires no tools. Ideal for steep ice, mixed terrain or expeditions. The advantages speak for themselves: every insert can be separately changed, and without any additional tool. Besides the inserts, there are no loose parts when ancending or descending. The inserts have no welding seams (risky points), no forged part (heat faults, brittle fractures). Detachable wrist loop with optimal power distribution.
