PETZL ICE SCREW LASER SPEED LIGHT is an ultra-high-performance ice screw with integrated crank. The ultra-lightweight LASER SPEED LIGHT is an ideal ice screw for mountaineering. The aluminum tube, associated with a steel drill, reduces the weight considerably. The integrated folding crank gives an optimized lever, making it easier and faster to screw in.
