Grivel Nepal S.A. Ice Axes
The Nepal S.A. by Grivel mates a standard Nepal head to a shaft that is slightly curved over its entire length. S.A. is shorthand for self-arrest and this axe was specifically designed to improve security while descending a snow slope -- when most falls occur -- and to arrest a slide more aggressively if the climber does fall. When a climber is descending, facing out, and holding the axe in the arrest position the shallow curve throughout the length of the shaft allows the axe to be driven in to a more secure position. Once placed, the curved shaft offers more holding power than a straight shaft; resistance is perpendicular to applied force so the geometry of a curved shaft is better than straight since the shaft's final position has more snow between it and failure. That same curve gives the pick a more aggressive bite when the climber pulls outward on the lower part of the shaft during an actual self-arrest. The axe is B-rated and features a forged and welded, carbon steel head mated to light alloy shaft. It is delivered with the Long Leash.
