So I went into last weekend all excited to do a bunch of routes at Frankenstein. First climb of the day, I started leading up a bulge at the bottom of Pegasus, got about 15 feet up, and had some difficulty getting a secure stance to place a screw. I looked down and saw something wrong with one of the front points on my Petzl M10 crampons.
Upon down climbing and investigating further, I saw that one point was broken cleanly in half between the mounting bolts, allowing it to flop around uselessly. It even broke through my anti-bott plate. Two of the other front points had small cracks visible in the same area around a casting mark.
Needless to say, this put something of a damper on my weekend. I got these 'pons about a year ago as a replacement for my Petzl Sarkens, which were recalled. They've seen ordinary use in New Hampshire less than 10 times. No abuse, or mixed climbing, just trade routes, really.
I think that with the fractures happening in the same spot consistently, this represents a clear manufacturing defect. Anyone who's currently using a pair of M10s, or other similar Petzl crampon should take a careful look at their front points for a similar issue.
I'll be contacting Petzl and will keep this thread updated.
