Hiking I carry an orange plastic shovel about the size of the U Dig It, not as heavy duty, but it's lighter and cheaper. In the van I keep an old wooden handle E-tool and GI Pick/Mattock. I'v picked up a couple of spare old style E-tools and 1 spare GI Pick/Mattock, as they are getting hard to find. An alternative is the East German folding E-tool. Looks much like our old wooden handle model, but has saw teeth along one edge.
There a few types floating around, not all have the saw teeth.
