Designed for ski mountaineering, glacial travel and high-end alpinism, the Ultralight Ice Screw says it all in the name. Weighing in at 45% lighter than Black Diamond's Express Screws, the Ultralight Screw combines a steel tip with an aluminum body and forged aluminum hanger that features two clip-in points. The innovative wire-gate Express handle shaves more weight and also clicks open and closed. The Ultralights are also easily identified by length with the classic BD color scheme.
