The Black Diamond Express Ice Screws' unique taper reduces ice fracturing and eases placements. A large crank knob takes less fine motor skills to use than a small one, so you can place the Express Ice Screw when you're pumped like crazy and really need it. Black Diamond uses a stainless steel hanger to eliminate rusting and decrease sun-induced melt-out. Two carabiner holes make sketchy hanging belays easy to set up.
Dual-clip in points make belays much easier to build
