The head, pick, and adze of the CAMP Corsa are all constructed with 100% aluminum and along with the CAMP Corsa Nanotech are the only such models in our review (all the other models use a steel head). Aluminum headed models are lighter weight but their picks need to be constructed wider to make up for its lack of strength and thus don't work as well in firmer conditions. With that said they work just fine if its not too icy.
My favorite thing about the Corsa is that at 7.5 ounces it is pretty dang light, half the weight of most of the ice axes in this review. The Corsa was pleasant to hold, especially in self belay (Piolet Cane position) where it was near the top of my review. In self belay position it was not nearly as nice as the Black Diamond Raven Ultra or the rest of the Raven series but better than the Snow Walker. While I wouldn't want to climb any steep ice with it, the bottom of the shaft has six machined grooves for better grip while swinging. This is a nice touch for pulling over the occasional bergschrund. As long as the snow wasn't too hard, we found this axe self-arrested relatively smoothly. Its spike is plugged up in the larger sizes to keep it from filling with snow, but is not plugged in the 50cm size.
The small aluminum adze chopped steps poorly and dug out tent platforms inadequately. It was at the bottom of the review. It worked well as a deadman but the holes in the adze and at the top of the shaft could have been designed a better to allow a larger range of carabiners to clip in. It was better than its big brother, the CAMP Neve, but not as nice as the Black Diamond Raven Ultra. Its self-arresting was rather average and not great in harder snow.
We would hesitate to pound many pickets with this ice axe for fear of damaging the aluminum head. We whacked away on a few for the review but never really tested its long-term durability. The aluminum pick doesn't penetrate nearly as well into ice as a steel or titanium pick and dulls far more quickly. It doesn't have a real spike and the 50cm version of the Corsa comes with an unplugged shaft. So the added weight of the snow packing into your ice axe is an unpleasant thought. But we learned to use it to fling snow at my partners and fellow testers.
The Corsa is most at home with ski mountaineers, early season backpackers, alpine rock climbers, adventure racers and anyone else where weight is the biggest factor. Climbers needing only basic requirements of an axe will enjoy the Corsa's nearly unnoticeable weight. Mountaineers looking for a durable axe or one that will chop steps and climb steep snow efficiently will be unhappy with the Corsa's sub-par performance in those categories. Those carrying an ice axe "just in case" will love the Corsa. Climbers with a quiver of axes will find that with it they can save an extra half pound or more on certain general mountaineering trips when conditions are right.
It isn't as versatile as many other ice axes even when compared to its ultra light competitors. So for $120, you only get an axe that excels at specific applications. If those applications are all you need the axe for, then it is not a bad deal.
