It is a carpenters axe. This type of axe was used for hewing a board to desired shape and thickness. It is said old timers used to laugh at the the young men who used saws to bring projects to final shape and thickness. Just one man's free opinion and no doubt worth twice the price.

Correct, as others have also pointed out. And, I'm certain the handle was curved outwards also. Knuckle saving design. It can be used for camp but a small bevel must be ground onto the flat side. Only you can decide if you want to do that to an antique. I have on similar and did bevel the blade.
