The Reactor Ice Tool is a leashless ice axe developed by Black Diamond, specifically designed for ice climbing and mixed mountaineering on technical and steep walls that require top-notch equipment. This ice axe is specially optimized for ice climbing through its design and construction. It features an innovative adjustable handle that adapts to the climber's hand size, providing excellent grip and significant climbing comfort, essential for routes that can take up to an entire day.Similarly, its extruded monobloc shaft is well curved to provide a large clearance surface, and its Natural Ice Pick blade with an open angle makes climbing easier by penetrating the ice like a needle. Additionally, it is very well balanced with a steel head and an aluminum plate, while offering the possibility to add a hammer or a adze from Black Diamond for mountaineering use. The Reactor Ice Tool is therefore a high-performance and extremely versatile ice axe that adapts to various icefall profiles.
