The Black Diamond Ultralight Ice Screws are super lightweight ice screw designed for ski mountaineering, glacial travel and high-end alpinism. 

Weighing in at 45% lighter than the Express Screws, the Black Diamond Ultralight Ice Screw is quick to bite and easy to crank in. The lightest ice screw in the world combines a steel tip with an aluminium body, and a forged aluminium hanger that features two clip-in points. The foldable speed-drive knob is colour-coded for quick length identification and offers uninterrupted 360-degree motion. The new Aluminium hangers are lighter than previous models and rack fantastically when put on an ice clipper. The Ultralight is built in four lengths to accommodate a variety of ice conditions.

The only trade off with saving 45% of the weight over the Express screws is that the material is less durable than the steel version and the threads will dent easier.  As a result these screws are designed for those ski mountaineering, glacial travel and high-end alpinism days where weight needs to be at a minimum.
