Here are a few pictures of my way to protect the ice-axe (apologize for the poor quality). How to attach these (one for the head and one for the spike) depends on your pack. My previous one (store-bought) for which this set-up was initially made, has two straps coming down from the lid and another two straps going under the bottom. Once you see the pics, you’ll get the idea of how I did it. Every pack is different, so you’ll have to figure out how to attach the protectors to yours.
1a. Protector of the head. Forget about the strap going down (with triangle D-ring) – at the moment I’m using an MYOG pack and this strap is part of same. The strap going up (on a normal pack, this could be much shorter) is fixed to de bottom strap of my pack with a triglide.
1c. Detail (other side). Pay attention to how the strap is winded around the adze and fixed with a trident buckle. The advantage: I can reach backwards with my hand to undo the buckle and grab my ice axe without having to take my pack of.
1d. Detail. Once again; forget about the strap with de D-ring going down.
2a. Protector of the spike. The “buckle” on the left (don’t know the name) is used to fix the protector to one of the strap coming down from the lid of the pack.
2b. Close-up of spike-protector.
2c. Same without ice axe.
2d. Close-up of fixing buckle (strap coming down from lid is going through this one).
2e. Same; seen from the other side.
2f. Complete spike protector.
2g. Close-up of bottom part of spike protector without ice axe.
Hope this is clear; if not, just ask.
