Disassembled Petzl Nomic
An issue well known to Petzl Nomics (and some other models of ice axe) is the tendency for the heads to loosen and develop movement over time. This is mostly due to the design – the head of the axe is held in by a single rivet. Over time the press fit between the head and the shaft gets looser. As there is only a single rivet the head can rotate around this and the overall effect is a wobbly or moving head.
