I love old-timey weapons and stuff in general, to include tomahawks. I have a nice one that a good friend made for me, the same was as you OP, from a ball pein hammer.

I have other friends who are crazy about them. I have seen suggested "be ready" vehicle loadout lists that included three tomahawks.

For me they are novelty/nostalgia only. I've played around with mine quite a bit and you can get to where throwing it, you almost "can't miss" at a certain distance. But for the zombie invasion / nuclear disaster / whatever scenario, if I found one in my otherwise filled-with-necessities vehicle, I would throw it out to make room for something else. As a weapon of course it would always be better than nothing but for the size and weight something else would be better. As a camp tool it is waayy inferior to an axe. If there is no axe and only a hatchet, in my opinion the hatched is a way more useful tool and it makes a better weapon.
