I think there's a difference between forecasting and being prepared.
"Forecasting" or
anticipating, is the first part of any prep. My point is simply that if you're acquiring a piece of equipment for possible situations that you've imagined could happen, then it isn't for "unforeseen" events, right?
The OP already said that he had purchased a CS shovel, so I think this thread has moved beyond recommendations for him, and to a discussion of shovels for camping & emergency use in general.
I know the OP originally asked about small camping shovels, but he also commented that the E-tool seemed under-sized, and I agree (I also own one). Which is why it's worth suggesting larger options, especially if it's for emergency vehicle use, regardless of the season. Shovels are pretty simple - bigger/longer ones are usually going to be a lot more efficient than shorter/smaller ones.
I keep an e-tool in the box of my truck, mainly because I already owned it and its really small, so why not. But if I truly need a shovel because I've driven off the road, or need to help someone else, or whatever, then the last thing I want to do is pull out that dinky little e-tool and be there moving small amounts of dirt or snow for hours. Bully makes a darn good shovel for the price (and made in the USA, unlike CS...), and it's still short enough that it will fit in the trunk of most cars. I'm not trying to be argumentative, just saying that a
good shovel is a smart thing to have and that you may as well carry the largest one you realistically can - you'll be glad you did. If you just want a little folding shovel for carrying into the backcountry, that's different. But personally, I've never found a need to take an e-tool backpacking.
