GRIVEL
Piolet The Light Machine Hammer

Designed primarily for technical mountaineering and for ice climbing.
Interchangeable ICE pick is tapered at the tip (3 mm) for easy penetration, even in cold ice. The stout Mix blade, 4.2 mm, will accept your “normal abuse” hooking on both ice and rock.
Sliders support your hand when you pull on them, and, sliding on the shaft, let the spike and handle penetrate the snow when you push on the axe.
Umbilical elastic sling makes it impossible to lose the tool.
