Venom Adze 2016
The ultimate hybrid axe for technical couloirs and rugged alpine terrain, the Black Diamond Venom bridges the gap between classic piolet and technical ice tool. The curved upper shaft provides added clearance during technical ice and snow sections, while the traditional spike makes for smooth plunging on the uphill. The dual-density grip and included Lockdown Leash increase security when things get dicey.
Climbs steep couloirs, plunges and self arrests.
Venom Adze comes with the Classic Pick.
Comfortable, dual-density molded grip.
Lockdown Leash included.

|Weight (g / oz)|
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.
| 523 g / 18.45 oz|
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.

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: B / Type 1|
Shaft: B / Type 1
The materials, as stated by the manufacturer / brand, of the pick, head, shaft and grip.
| Pick: Chromoly Steel|
Head: Stainless Steel
Grip: Dual-Density Molded Grip
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"
The Venom's aluminum shaft is thin, and plunges into the snow well, especially due to the no-frills spike at the end. The rubber grip never impeded the plunging action as far as I could tell, but it was sticky and easy to grab. A set of Venom tools, especially if you paired a short hammer with a longer adze tool, could tackle the majority of mountaineering challenges, whether it's building snow anchors, low-angle terrain, even steep and technical ice. The Venom hammer comes in 50 and 57 centimeter lengths; the adze gives you a choice of 50, 57 and 64 centimeters.
