A nice safe collapsible non-technical iceaxe

Snow climbing is great, but packing iceaxes and travelling with them can be a nightmare. If the Iceaxe blades could be folded down inside the body of the handle when not in use, they would become soo much safer / more portable. Care would have to be taken to ensure that the heads, when un-collapsed, were mounted strongly enough and I doubt whether a technical ice-axe could ever be collapsible.

       Wouldn't the ice/snow freeze this shut? And, when I might need such a device, I'd hate to try to get it unfolded while wearing gloves/mittens.   

       Maybe add a chemical stick inside that heats it up to melt ice and unfold easier, and at the same time, would aid in poking through ice.   

       Or, in emergency situations, add a flare at the end of the shaft to both heat & shine.

       [soph] I hadn't thought about it icing shut. However I guess that during an expedition it would be kept unfolded. If the release mechanism were activated by rotating a section of the handle, it should be fairly easy to operate with gloves etc.   

       I like the idea of the flare aswell. you could hack it in and then let off the flare :)

       Only the tip(s) need to recess into the handle for it to be safer. There could be enough exposed to grip / open easily if it ices. Spring-loaded? I'm trusting this as a clibming tool even less, but you did specify non-technical. +

       The springs would only be used on opening, once open, there would need to be another method for locking them open.

       Could the handle be hollow? If so, the axe-y bit could be stored inside the handle and screwed onto the end when required.

       That was my thought. Provide a gravity catch on each handle so the axes won't open when hung off one's belt, but only when held upright.
