Nobody makes better ice axes than Grivel, and while I am sometimes lured away by other brands, each time I pick up a Grivel product I am impressed with its quality. This axe is no exception.
The cold-forged steel head and spike really make a difference in durability when compared to other axes. I have used this axe in plenty of situations where a lighter-weight aluminum axe would likely bend or break. Mine has chopped steps in unusually firm neve, hammered pickets, and been used as a janky belay anchor. This is a tool for mountain travel, not an expensive piece of cheap aluminum (I'm talking to you, CAMP...) However, at a little over 14 oz the AirTech isn't very heavy.
This was not my first axe, although it would make an excellent first tool if you are not yet familiar with ice axes. The ergonomics of the head and the slightly bent shaft make carrying the axe comfortable, even over long periods of time. Though some axes, like the BD Raven series, do have a slightly more comfortable hand position.
Personally, I bought it to replace my first axe (BD Raven), to use on climbs where I only needed one tool, and don't plan on climbing anything too steep with the axe. (mostly summer climbing, in the Tetons, Bugaboos, Cascades, or Sierras). I will take it when I plan on mostly walking up steepish snow and neve. In other situations I would might want something either more technical, or lighter weight, but often times the Grivel Air Tech is the right tool for the job.
In short, this mountain tool is a good balance of useful, durable, and lightweight.
