That would actually be a good thing, I think. Entrenching tool should not just be “works exactly as well as a full sized shovel, but doesn’t take up as much space” because then, full-sized shovels wouldn’t be made anymore.
“Able to do everything a full sized shovel can do, but just takes a bit more effort” sounds just right, actually, which is what I assume the hunger/thirst penalty is meant to simulate?[/quote]
Entrenching tools are meant to be used when you are laying on the ground. Regular shovels are meant to be used standing.
