Like was already said, a tool is a tool. I've had some fun taking a grinder to axe heads with no collector value and making a "bearded" pattern or other modification. That one looks like it could do with the poll being cleaned up, which you could do with a grinder OR if you've some patience you could cold hammer it back with a ball-peen and get that hand-hammered look. All in all it's a head you can play with using whatever shaping and grinding techniques you want to try out and then you get to make a cool handle as well. Now you've got a unique hatchet all your friends will be jealous of.
