Air Tech Evo Adze W/Slider
The new version of the famous Air Tech axe. The head, which is hot forged from a single piece of steel, has become an established alpine classic. The new shaft’s gentle curve just below the head gives greater clearance and makes anchoring easier on any sort of terrain, whilst the lower straight part of the shaft will penetrate into snow with little effort. Also available with the new Easy Slider, the new hand rest that slides to the top of the shaft when sunk in snow or to the bottom to support hand in traction. The most advanced axe technology, all in under 500 grams! Both Axe and Hammer are the same weight.

Weight (g / oz)
In grams and ounces, the weight, as stated by the manufacturer/brand.
Since the most common ice axe length is 50cm that is the main length that we reference.
When available, we list the weight for each length here.

The lightest axes available, used most for ski mountaineering, adventure racing, and other "go light" ascents. 350 grams is usually the max weight. The decreased weight means they are axes are built for snow missions, not ice.
This is the most common type of snow mountaineering axe. These axes are above 350 grams and are a great balance of weight and durability. There may be a grip and they will always have an adze head (and no matching hammer pair). These axes are great for snow and can handle chopping steps in ice, or other small ice scenarios.
These axes are for tougher conditions when the majority of climbing is on snow, but the axe needs to be able to handle a short ice wall. They generally have a bent shaft and T-rated (more technical) pick. Often these beefier axes will have a rubberized grip and they may have a matching adze and hammer version. They're basically the offspring of an ice axe and ice tool.
|Length Options (cm)
Length Options (cm)
Measured in centimeters, the best length is based on your height and ape index (arm length). Holding the axe in your hand, the spike (sharp end) of the axe should arrive around your shin. At the max size, it should go to your ankle.
Two people of the same height could need a different sized axe, based on arm length (t-rex vs monkey). If in-between sizes, our bias is towards sizing shorter.
Rule of Thumb
There are other resources online that suggest a longer axe is a plus and that you should measure below the ankle. We absolutely disagree. A longer axe means you'll be tempted to use it as a trekking pole (which will put you off balance), or you'll have to give your arm a huge workout just to lift it in and out of the snow. Ice axes are meant to be used on the uphill side, which is already much higher.
|48 cm, 53 cm, 58 cm, 66 cm|
This refers to the back of the ice axe head (opposite the pick).
For ice axes, adze's are (by far) the most common. An adze will allow you to break ice by chopping or shoveling in a specific area, and they also provide more room to hold on to the head than a hammer does. This grip helps for arresting too.
Hammers are usually only used as a pair with an adze on the other axe (hammer's are much more common in ice tools than ice axes). A hammer uses a more broad force to break ice bulges.

The certified rating of the pick and the shaft. These ratings might not match each other.
There are only 2 possible shaft ratings:
B / Type 1 / CEN-B: Basic
| Pick: |
Shaft: T / Type 2
The materials, as stated by the manufacturer / brand, of the pick, head, shaft and grip.

Head: Chromolly Steel
The main climbing gear certifications are CE and UIAA--and normally the UIAA creates the rules that the CE body also supports. When possible, we try to list all the certifications the product carries.
To sell a climbing product in Europe, the device must be CE certified. There are no official requirements to sell climbing gear in the US. The UIAA certification is a voluntary process.
For ice axes, there is a separate certification for the pick and the shaft.
This isn't super common, but sometimes the manufacturers will state a specific warranty such as "3 years against manufacturer defects"
In conclusion, the Grivel Air Tech Evolution ice axe set is a great ‘semi’ technical set of winter tools that will serve you well through many years of use and abuse. They are light, well balanced and the hot forged head is a great bonus for hooking, bullet hard ice or that super crispy neve we all dream of climbing.
Next to your climbing partner, your axe is your most trusted friend on a big mountain. The Grivel Air Tech Evolution axe will be there for you when you need it, and at only 16.1oz it won't be a burden. Unlike, for example, certain climbing partners we have all known. This axe had no problems standing up to a good two-week pounding on Denali after a season of continous use. It plunges well, has a no-slip grip and the slight bend allows it to reach over bulges like a tool. Pair it with Grivel's Dragonne Leash for protectus maximus.
