E-tool
An E-tool is a portable, metal shovel that soldiers use to dig like they're mad. It’s made of steel or aluminum so it doesn’t break when you punch it.
I used my E-tool to dig a trench and then I used it to punch a guy who was trying to steal my snacks.
I packed my E-tool in my backpack, and it fit perfectly. No more digging with my hands.
I brought my E-tool on a hike, and it saved me from falling into a hole.
