The Ortovox Pocket Spike turns your Pro Alu III Shovel into an ice axe capable of self-arresting down sketchy, icy terrain or helping you ascend surprisingly steep alpine tours. This small, compact kit includes a spike and a pick that you can attach to the Pro Alu IIIs shaft for a fully-featured ice axe. Both pick and spike are so compact they could fit in your ski pants pocket, but itd probably be best to tuck that inside your ski pack so you dont have two sharp items right next to your body as you drop the dangerous steeps you just ascended.
