Familiarity: I've put it through the wringer
I've used a pair of these for the past 7 years of ice climbing about 30 days/yr. Each year I file them down and their end might be coming to a close. They climb everything really well from WI1 scrambling to WI5 and have never had any problems as well as mild mountaineering found in New England. They fit great in Kayland Apex XT, Sportiva Nepal and Koflach boots that I have. Though an issue with all the Petzl crampons is their tiny buckle which is almost impossible to use with gloves on when you're cold and tired at the end of the day. Over time their front tip point becomes quite rounded and no matter how much I file, can't seem to get that pointy at the tip. That may be an issue with all crampon points.
