What is an ice axe?

In the world of mountaineering and alpine exploration, few tools are as iconic or essential as the ice axe. This versatile implement has been the trusted companion of climbers for centuries, evolving from a simple shepherd’s tool to a highly specialized piece of modern equipment. Whether you’re a seasoned mountaineer, an aspiring alpinist, or simply curious about outdoor gear, understanding what an ice axe is and how it functions is fundamental knowledge in the realm of mountain craft.

The Essential Mountaineering Tool: Understanding Ice Axes

An ice axe is a multi-purpose tool used by mountaineers, alpinists, and winter climbers for travel over snow and ice-covered terrain. At its most basic level, an ice axe serves three primary functions: providing stability and balance on slippery slopes, aiding in ascent by allowing users to gain purchase on steep terrain, and perhaps most crucially, enabling self-arrest to stop a slide or fall on snowy slopes.

As described by the American Alpine Club, the ice axe is “the end product of a long history of tools being adapted, redesigned and specialized” to meet the needs of those who venture into alpine environments. The modern ice axe represents centuries of refinement, reflecting both technological advances in materials and the evolving techniques of mountaineering itself.

The Anatomy of an Ice Axe

To understand an ice axe, one must first become familiar with its components. Each part serves specific functions and contributes to the tool’s versatility.

The Head

The head of an ice axe typically consists of two parts:

1. Pick: The toothed, pointed end of the head that can be driven into snow or ice. The pick is the primary component used in self-arrest maneuvers and can also provide secure anchor points on steeper terrain.
2. Adze: The flat, hoe-like feature on the opposite side of the pick. The adze is used for chopping steps in hard snow, cutting blocks for snow shelters, and clearing areas for belays or campsites.

Some technical ice axes replace the adze with a hammer, which is useful for driving in protection such as pitons or ice screws.

The Shaft

The shaft of an ice axe may be straight or curved, depending on its intended use:

1. Straight Shafts: Ideal for general mountaineering as they allow the axe to be used as a supportive cane on low-angle terrain and can be plunged vertically into snow for anchoring.
2. Curved Shafts: Feature a slight bend that provides clearance to keep the hand off the snow when placing the pick into steep slopes. More pronounced curves are found on technical ice-climbing tools for greater clearance and leverage.

Modern shafts are typically made of aluminum alloy or carbon fiber, though historically they were crafted from wood.

The Spike

The bottom end of the shaft features a sharp point called the spike. This component penetrates snow and ice to provide secure support when walking and makes it easier to plunge the axe into snow for belay or rescue operations.

Additional Features

Many ice axes also include:

• Carabiner Hole: Located in the head for attaching a leash or for use in anchor systems
• Grip: Rubberized or textured areas on the shaft for improved handling
• Leash: A strap system that secures the axe to the user’s wrist or harness

The Historical Evolution of the Ice Axe

From Alpenstock to Modern Tool

The ice axe has a fascinating evolutionary history that mirrors the development of mountaineering itself. The earliest ancestor of today’s ice axe was the alpenstock—a long wooden pole with an iron spike tip used by shepherds and hunters in the Alps during the Middle Ages.

As highlighted by the American Alpine Club, “The oldest ancestor of the ice axe is the alpenstock…invented sometime in the middle ages, the alpenstock was created to do the work of crampons.” These early tools were primarily used for balance and stability on snow-covered slopes.

When Mont Blanc (Western Europe’s highest peak) was first climbed in 1786, Jacques Balmat and Michel-Gabriel Paccard carried two separate tools: an alpenstock for balance and a small hatchet for cutting steps in icy slopes. According to historical records, these two implements were combined to create the first true ice axe around 1840.

The development continued as mountaineering gained popularity:

1. Early 19th Century: The first ice axes appeared, featuring vertical adzes similar to conventional axes.
2. 1860s: The adze was rotated to a horizontal position, significantly improving its utility for step-cutting.
3. Late 19th Century: Ice axes became standardized with slightly longer picks and horizontal adzes on wooden shafts approximately 120-130 cm in length.
4. Early 20th Century: Oscar Eckenstein pioneered the trend toward shorter ice axes (85-86 cm), which was initially controversial but eventually became the standard.
5. 1960s: Yvon Chouinard introduced a revolutionary ice axe design with a 55 cm shaft and dramatically curved pick, marking the beginning of modern ice axe design.
6. 1970s: Technical ice tools emerged, designed specifically for waterfall ice climbing.
7. 1980s-Present: Continued refinement has led to specialized tools for different applications, from ultralight mountaineering to competition ice climbing.

Material Evolution

The materials used in ice axe construction have evolved dramatically:

Era	Head Material	Shaft Material
Pre-1900s	Wrought Iron	Wood (oak, ash, hickory)
Early 1900s	Carbon Steel	Wood with reinforcement
Mid-1900s	Steel Alloys	Wood, then aluminum
Late 1900s	Forged Steel, Chromoly	Aluminum Alloys
2000s-Present	High-grade Steel, Titanium	Aluminum, Carbon Fiber, Composites

Types of Ice Axes and Their Applications

Modern ice axes come in various forms, each designed for specific uses. Understanding these distinctions is crucial for choosing the right tool for your adventures.

Technical Specifications and Ratings

B vs. T Ratings (Type 1 vs. Type 2)

Ice axes are certified according to standards established by organizations like the UIAA (International Climbing and Mountaineering Federation) and CEN (European Committee for Standardization).

B Rating (Basic) / Type 1:

• Designed for general mountaineering
• Subject to less stringent strength tests
• Suitable for snow slopes, glacier travel, and emergency self-arrest
• Not intended for technical climbing or belaying in demanding situations

T Rating (Technical) / Type 2:

• Undergoes more rigorous strength testing
• Can withstand greater forces and torque
• Suitable for technical climbing and belaying
• Required for mixed climbing and vertical ice

Both the shaft and the pick of an ice axe receive independent ratings. Some axes feature T-rated shafts with B-rated picks or vice versa, depending on their intended use.

As noted by Furnace Industries, “Tools that receive a ‘T’ rating have to pass 4 physical tests: .9 Kn pull at 90° to the shaft of the tool, 3.5 Kn pull at 90° on the center of the shaft, 4 Kn pull at 90° on the head of the tool, and a 182 N Pick Deflection Test.”

Size and Length Considerations

Selecting the correct ice axe length is crucial for efficiency and safety. The traditional method for determining proper axe length is as follows:

1. Stand upright in a relaxed position while wearing mountaineering boots.
2. Hold the head of the axe in your hand with the spike pointing toward the ground.
3. The spike should reach approximately to your ankle or slightly above it.

This method generally results in axes between 55-70 cm for most adults, though modern preferences tend toward shorter axes (50-60 cm) for increased versatility.

User Height	Traditional Axe Length	Modern Recommendation
Under 5’5″ (165 cm)	55-60 cm	50-55 cm
5’5″ to 5’10” (165-178 cm)	60-65 cm	50-60 cm
Over 5’10” (178 cm)	65-70 cm	55-65 cm

It’s worth noting that terrain and activity also influence length selection:

• Shorter axes (45-55 cm) are preferred for steeper terrain and technical climbing
• Medium-length axes (55-65 cm) offer the best versatility for general mountaineering
• Longer axes (65+ cm) provide better balance on low-angle terrain but can be unwieldy for self-arrest

Using an Ice Axe: Techniques and Best Practices

Walking and Balance Techniques

The Cane Position

When traversing moderate snow slopes (up to approximately 30°), the ice axe is often used in the “cane position” or “piolet canne”:

1. Hold the axe in your uphill hand with the pick facing forward.
2. Plant the spike into the snow for additional stability with each step.
3. Keep the axe shaft angled slightly behind you for optimal balance.

This technique provides a secure third point of contact with the slope, significantly enhancing stability.

The Self-Arrest Grip

On steeper terrain or when the risk of slipping increases, holding the axe in the “self-arrest position” allows for quicker response to a fall:

1. Grasp the head of the axe with your dominant hand, placing your thumb under the adze.
2. The pick should point backward, and the shaft should extend down along your arm.
3. Keep the axe ready to pivot across your body in case of a fall.

Self-Arrest Technique

Self-arrest—the technique of stopping yourself after a fall on snow—is one of the most critical skills for mountaineers to master. While this article can describe the technique, proper instruction and practice are essential.

The basic self-arrest procedure includes:

1. Initial Position: As you begin to slide, roll onto your stomach if not already there.
2. Axe Placement: Position the ice axe across your chest with one hand on the head (pick pointing away from your body) and the other on the shaft.
3. Body Position: Get into a push-up position with your feet slightly apart.
4. Application of Force: Drive the pick into the snow while pushing your weight onto it.
5. Controlled Stop: Maintain pressure until you come to a complete stop.

Different falling positions require variations of this technique:

Initial Fall Position	First Action	Secondary Action
Sliding on stomach, head-first	Plant pick while pushing upper body up	Keep legs raised slightly
Sliding on back, feet-first	Roll onto stomach	Execute standard arrest
Sliding on back, head-first	Roll onto stomach while rotating 180°	Execute standard arrest
Sliding on side	Roll onto stomach	Execute standard arrest

Self-Belay Technique

Self-belay involves using the ice axe as a preventive measure to avoid a fall in the first place:

1. Shaft Plunge: Drive the shaft of the ice axe vertically into firm snow up to the head.
2. Hand Position: Maintain a firm grip on the head of the axe.
3. Weight Management: Use the axe as support while moving your feet to a more secure position.

This technique is particularly useful on steep terrain where a fall would have serious consequences.

Step Cutting

Before the widespread adoption of crampons, cutting steps was the primary method for ascending steep snow and ice. Though less common today, step-cutting remains a valuable skill:

1. Grip: Hold the axe near the head with one hand and place the other hand lower on the shaft for leverage.
2. Swing: Use the adze to chop downward and inward into the slope.
3. Clear: Remove loose snow to create a level platform.
4. Progression: Continue upward, creating a staircase pattern.

Step cutting is energy-intensive but can be essential when crampons are unavailable or the snow conditions make them ineffective.

Safety Considerations and Best Practices

Training and Practice

No written guide can replace proper instruction and practice. Before relying on an ice axe in critical situations, consider the following:

1. Formal Instruction: Take a mountaineering course from a qualified guide or organization.
2. Practice Environment: Train self-arrest techniques on moderate slopes with safe runouts.
3. Progressive Learning: Start with basic skills before attempting more advanced techniques.
4. Regular Refreshers: Practice these skills at the beginning of each winter season.

Leash vs. Leashless Considerations

Whether to use a leash with your ice axe is a topic of ongoing debate among mountaineers:

Pros of Using a Leash:

• Prevents loss of the axe if dropped
• Can reduce fatigue when the axe is used for extended periods
• Provides security when traveling through consequential terrain

Cons of Using a Leash:

• Increases time spent switching the axe between hands when traversing
• May pose a hazard if you fall and lose control of the axe
• Limits your ability to quickly use the axe in different positions

Many mountaineers now opt for a leashless approach on moderate terrain while using tethers (connected to their harness, not wrist) for technical climbing.

Maintenance and Care

Proper maintenance ensures the longevity and reliability of your ice axe:

1. After Use Cleaning: Rinse with fresh water and dry thoroughly to prevent corrosion.
2. Storage: Store in a dry environment, away from corrosive substances.
3. Pick and Spike Maintenance: Sharpen when necessary using a fine file. Note that over-sharpening can weaken the metal.
4. Inspection: Regularly check for cracks, loose components, or deformation.
5. Protection: Use rubber protectors for the pick and spike during transport to prevent damage to other gear and for safety.
