Offhand, it looks like a cheap version of a mountaineering (avalanche). On a high mountain or a glacier, a good, sturdy shovel is a vital tool - not the kind of implement to go cheap on. I have used shovels a lot doing archaeology and wildland fire fighting where they are effective and versatile. If I could have just one tool on a fire line, it would be a shovel, but in those situations, weight is much less of a concern. What you need there is a stout (really stout) handle which the lifeline clearly does not possess.

For non-mountaineering situations, various military entrenching tools work rather well, and they are reasonably compact. You can put a sharp edge on any digging implement, and I do so on nearly all of mine. It improves their effectiveness remarkably
