Trail Magazine just awarded it their “best for climbing” award in January 2012 issue . They reckon that this new ice axe is:
“perfectly balanced for both plunging and swinging and the trigger can be put in the perfect position depending on what technique you are employing. A flexible axe that will take on everything from winter Munros to fairly technical climbs.”
Another set of rave reviews comes from the American Alpine Institute which gave it a “guides choice” award. They say that the Petzl Sum’Tec:
“combines the qualities of a technical mountaineering ice axe – thanks to its curved shaft – and a classic mountaineering ice axe. Light and versatile, this ice axe has an adjustable hand rest and an interchangeable pick.”
Outdoor Gear Lab also really liked it. They said:
This is one of the heavier ice axes we tested and a little overkill for moderate routes. But if you climb a lot of steeper terrain, this ice axe is tough to beat.
Speaking of weight, The Petzl Sum’Tec ice axe weighs in at a respectable 485g for the 52 cm shaft. This is a T-rated shaft and comes in 52cm or 59 cm lengths (the longer one weighs in at 505 grams)
