Black Diamond Raven Mountaineering Axe - Redesigned with an up to 50 gram reduction in weight, this classic piolet optimizes comfort and ease of use when glacier traveling and mountaineering. Like all of Black Diamond's piolets, the anodized shaft is built from lightweight, aircraft aluminum alloy for high strength. The investment-cast, one-piece stainless steel head is comfortable to wrap your fingers around, and the slim, neutral pick and aggressive teeth are engineered for secure self-arrest.
