Bought these about 1967 when I enrolled in the Seattle Mountaineers "Intermediate" class. They wouldn't let newbies in the "Basic" class use 12 point crampons (back then that meant front point). So I climbed with a ten point crampon for a year with no forward facing prongs, which I still have... These pictured pons are lighter than anything I can find now accept aluminum which are no good on mixed routes climbing over rock, so I just use these for memories and the practical value....they work fine. Post your old gear you still use. 1/17/15
