In my opinion this is a tool with a very specific use. It should not be your all around piolet or even considered a general mountaineering axe and should not be replacing your old piolets (for example BD raven). I've watched the adze and head snap off when cutting steps in moderately firm neve, seen the shaft bend, and the steel pick disintegrate when swinging into junky ice. That all being said I still really like this axe as a specific tool for certain ski or climbing missions, where I will most likely not need an axe, and if I do it will be simply for snow walking and or that one small patch of ice. This is primarily a ski mountaineering tool for skimo racing where they are required to carry one and or they do not need many of the functions of normal piolet.
Some things to keep in mind that the head and spike do not have compatible or usable clip in points, and the head is not rated (I've watched them break). The skillset of proper piolet technique and usage has somewhat been forgotten, and unfortunately this tool cannot do with any bit of confidence the majority of things even a standard BD raven can do.
That all being said, the thing is insanely light and the shorter lengths fit in a pack nicely. The grip on the shaft is just a bit of grip tape but it seems to work well, and for the very small amount of time this guy gets used it seems to get the job done.
This should be an addition to your axe quiver not a replacement to an already owned axe.
