I can add that although i usually find light axes hard to cut steps with the adze on this seems razor sharp. Great for cutting steps/ledges, less ideal when I leant over one sitting on my downmat. "Puff" and the snow hole filled with feathers
Anecdotally too I had a light person trying unsuccessfully to self arrest with a light axe on firm neve on a course and the moment I gave them my big chunky mountaineering axe they were able to stop successfully. Just another consideration but maybe not the primary one.
