Ice axe alpine

The alpine ice axe is an essential tool for ice and snow climbing, combining safety and technique on glacial mountains.

About this subject

The alpine ice axe is a fundamental tool for mountaineers tackling glacial terrain and snow-covered slopes. Its origins date back to the 19th century, when European alpinists began exploring the Alps more boldly. The basic design includes a metal head with a sharp pick (point) and an adze (or blade) for cutting steps, plus a long shaft ranging from 60 to 90 cm, typically made of aluminum or steel. Modern models use lightweight alloys and ergonomic shafts to reduce weight and increase efficiency.

Using an ice axe requires refined technique. It serves as a third point of contact, helping balance on steep inclines. In case of a fall, the mountaineer can perform a self-arrest, driving the pick into the ice to stop the slide. Different types of ice axes are designed for specific activities: walking axes for glacier crossings, and technical axes for vertical ice climbing, with more pronounced curvature and shorter shafts.

In Brazil, ice axe use is limited to expeditions on snowy mountains such as Mount Roraima or in Patagonia, though most practitioners train on glaciers in the Andes or Europe. The shaft length should suit the user's height: the tip of the ice axe should reach the ankle when held by the head with arm extended. Traditional brands like Petzl, Black Diamond, and Grivel dominate the market, with innovations such as carbon fiber shafts and shock-absorbing systems.

Trivia: the term 'ice axe' also refers to the technique of cutting steps in ice, a practice requiring precision and strength. Maintenance includes periodic sharpening of the pick and inspection for cracks in the shaft, as failure can be fatal at altitude.

Frequently Asked Questions

What is the ideal length for an alpine ice axe?

The ideal length depends on the user's height. Generally, the tip of the ice axe should reach the ankle when held by the head with arm extended. For snow mountaineering, shafts of 70, 80 cm are common; for technical ice climbing, shorter shafts (50, 60 cm) offer better maneuverability.

How do you perform a self-arrest with an ice axe?

During a fall, hold the ice axe with both hands, one on the head and one on the shaft near the head. Drive the pick into the ice or snow firmly, using your body weight to stop the slide. Keep your feet raised to avoid crampons snagging. Practice on safe terrain before real situations.

What are the main brands of alpine ice axes?

The most renowned brands are Petzl (models like Summit and Nomic), Black Diamond (Raven and Viper), and Grivel (Air Tech and G1). Each offers variations for walking and technical climbing, using materials such as aluminum, steel, and carbon fiber.
