Quick 10 minute Photoshop analysis of ice axe geometry.
This is completely unscientific and should be taken with more than just a grain of salt.
Assuming identical grip position DMM Switch seems to match Nomic almost perfectly. There is a slight difference in the upper shaft angle but pick tip is pretty much in the same place.
Apex is basically the same just with a straight grip/handle.
Ergo is of course far more curved, not even in the same league.
Make your own conclusions.
