    Petzl made the Sum'Tec Ice Axe light and versatile for mountaineering across glaciers and climbing steep terrain. Its thin Alpix pick effectively penetrates ice and is quickly and easily replaced thanks to Petzl's unique screw lock system.The stainless steel spike allows for secure piolet-canne positions over flat to moderately steep ground. The Trigrest handle can be adjusted up and down the axe for efficient use in technical passages, bergschrunds, and ice gullies. The Sum'Tec is available with either an adze for cleaning snow and ice, or a hammer for placing pitons.

    • Familiarity: I've used it several times

    I picked this axe up last minute for a trip down south ski mountaineering this summer. I have a few different axes at this point but needed something a little more solid and versatile for all the late season ice down in Patagonia but that will also perform basic functions, especially in glaciated terrain. I've previously used the hammer version in 52cm, and liked it and thought the adze would be a good all around option for this trip. The length at 52cm is ideal for steeper snow, couloir climbing, working your way around cornices, bergschrunds and for added security in tricky places. Just as the description says. Length is ideal for traveling as well because it fits into a medium sized north face duffel and the lighter weight is a big help and an added benefit for the conscious traveler. In terms of performance, the pick grips nicely, penetrates ice easily and keeps you secure. I like the shape of the shaft as I get a secure plunge when climbing steep snow. This is a versatile little tool not to be left at home and a great travel option for ski mountaineers unsure of exactly what kind of conditions they will encounter on their adventures. One drawback is the movable trigger handle, which gets in the way when I store the axe on the back of my pack or throw inside a shoulder strap. Some kind of grip tape on the bottom of the shaft would be better. I generally do not use the trigger and have pushed it pretty high up the shaft toward the spike. I suppose in certain situations of harder, more technical ice it could be useful to bring it down to add extra grip. However, I haven't used this function at all and in these situations may rather bring a more aggressive tool. All and all, I recommend this as a versatile option, especially for traveling ski mountaineers.
