Black Diamond Reactor Ice Axe Set of 2 The Reactor is a model developed for ice climbing, and I believe the concept was that the angle of the axe wouldn't change when switching hands, making it difficult to dislodge. One side of the grip has been slightly shaved to make it easier to hold. Pick covers are included as a bonus. Please note that they may be weakened due to the aging of the resin. These items have been used for climbing. Please understand and accept this before purchasing. Returns and exchanges are not accepted.
