The Laser Speed Light from Petzl is an ultra-light ice screw that grips quickly thanks to the optimized shape of the steel teeth. Screwing it in is even lighter thanks to the fold-down crank. If the teeth need to be sharpened, the patented sharpening reserve makes this easier. And thanks to the ultra-light aluminum shaft, you no longer have to lug around so much weight on your harness. These are arguments for a super ice screw, aren't they?
