That looks a lot like my dad's old 'grub hoe,' but on a smaller scale.

I have a big knife somewhere between a Bowie and a kukri in my kit, but a hatchet has lots of uses, and in a survival/subsistence situation, the hoe would be invaluable.

What do you think of entrenching tools and other folding shovels? Better for digging, but not as good for garden work?
