I own the 65cm and the 55cm. They are great, and so, so light. I've used them to self arrest myself on multiple occasions and they dug in well, but not so aggresively that it ripped the tool form my hand. The shaft is a good diameter for a solid grip, whiel not being so beefy that you can't get your fingers around it. The adze is small, but very sharp and you have to sacrifice something for the weight. It even climbs short, near vertical alpine ice pretty well.

Perhaps this axe IS too light for all-around use, but it is a great piolet. It woked fine on Rainier for glacier travel and as a second tool for a couple pitches of ice. I did not have to drive pickets, however. The Raven would be better for driving pickets and as an all-around mountain axe. Fit and finish of the tool is stellar.

Used this mtn. axe on Baker’s N Ridge, (AI 2-3), last June and although it performed well I didn’t like for the strangest of reasons. It was to lite! Odd thing to say, yes but I felt that it required too much swing to find a good purchase in the ice. I did however like its pick and adze. The pick is design aggressive enough and the adze performed well for chopping. For basic glacier and self arrest practice it work well also but I would prefer a little larger grip. One of my partners used a Raven Pro on Mt. Washington’s Huntington’s ravines and bent the pick with one swing onto ice/rock. Pick is none serviceable.

Full service and light as a feather. I don't know what else to say. This is a great mountaineering axe. The only down side is the price, but all extra light, strong products are expensive.
