Griprest for the 2010/11 Nomic and Ergo.
It has a blade that is toothed on the lower side to improve grip when daggering (piolet-canne).
Contrary to previous advice that it does not fit previous models, we are now informed by Petzl, "Yes, I confirm that the Griprest is compatible with old Nomic ice axes."
Price is per single item, not for a pair.
Petzl code is U21 GR3.
NB Does not fit the latest 2018/9 models.
