Ive got the GLOCK folding shovel and used to have an old E-Tool but must admit to not being keen on the folding feature.
Some of the folding shovels look to be a bit 'gimmicky,' not very sturdy and maybe even wobbly. Not least some in this thread (just my opinion and I may be wrong).
Does is have to be able to fold and do you need the attachments?
As mentioned I find that type of shovel gimmicky and I for example never use the stashed saw in the GLOCK shovel.
IMO its better to carry a dedicated shovel that works, when you need it instead of some wobbly thing which might not be too sturdy or which might break.
I got a titanium shovel directly from Russia (supposedly military) - well, two small titanium shovels actually - and they are pretty solid and well made. Cheap as well even with shipping.
If you want a compact solid shovel, which weighs next to nothing, maybe check out the Russian titanium shovels.
I often pack one or both in/on my ruck and never even notice, as they are both so light weight. A compact saw is strapped to the pack as well.
Heartedly recommended.
The first one has a wooden handle. The second smaller one was ordered wothout a handle. Its used for covering the fire/embers after use amongst other jobs.
A small Bacho Laplander or this Agawa is often carried as well depending on the trip and tasks. Neither weighs much and both are compact. Neither shovel nor saw would be in the way and Ive carried both on a mid-sized ATV.
