Good man, mine arrived today.
I was initially hesitant due to the price, and because I read on one of the army forums that someone had been ordered to file the edge and use it to fell a tree as part of the exercise they were on. My BS meter hit the high note at a hinged shovel being capable of doing this. Wrong, it could easily do it, and it's good value for money.
In hand, this ain't no backpacking cat holer, it's a boot of the car shovel. It weighs at least as much, if not more than a full side garden spade. I have a snow shovel attachment on the way from a mate in Sweden, should make it a very good addition to my car boot stash of 'stuck out in the cold' gear.
Thanks for the link. As is often the way, I probably didn't need one, but I enjoyed all the research and self justification that led me to a product that's put a grin on my face.
